　本開示は、画像評価システム、画像評価方法、加飾シートのサンプルの製造方法および加飾シートの製造方法に関する。また、本開示は、加飾シートの絵柄の変形を評価するための評価方法及び評価装置、並びに、加飾成形品の製造方法に関する。 The present disclosure relates to an image evaluation system, an image evaluation method, a decorative sheet sample manufacturing method, and a decorative sheet manufacturing method. The present disclosure also relates to an evaluation method and an evaluation device for evaluating deformation of a pattern on a decorative sheet, and a method for manufacturing a decorative molded product.
　例えばＪＰ２００５－１０３７９４Ａに開示されているように、従来、自動車の内装部品や外装部品、建材の内装材や外装材、家電筐体として、樹脂成形品の表面に加飾シートを積層させた加飾成形品が用いられている。このような加飾成形品の製造工程では、加飾シートは、樹脂成形品の表面の形状に追従するように、樹脂成形品の表面に積層される。加飾成形品の製造は、例えば、成形型を用いて行われる。 For example, as disclosed in JP2005-103794A, conventionally, as interior and exterior parts of automobiles, interior and exterior materials of building materials, home appliance housings, decorative sheets are laminated on the surface of resin molded products. Molded products are used. In the manufacturing process of such a decorative molded product, the decorative sheet is laminated on the surface of the resin molded product so as to follow the shape of the surface of the resin molded product. Manufacture of a decorative molded article is performed using a shaping|molding die, for example.
　しかしながら、加飾シートの意匠開発において、意匠を検証するために加飾シートのサンプルを製造したり、加飾成形品を製造するための成形型を製造したりすることが必要である。そのため、開発する意匠の点数に応じて、試作すべき加飾シートのサンプル及び成形型の数が増える。これにより、意匠開発にかかる負担が増えたり開発期間が長くなってしまったりする。さらに、加飾成形品の表面形状や成形型の成形面の形状によっては、加飾シートが樹脂成形品の表面に積層されるとき、加飾シートの一部の領域が著しく伸長する。この結果、成形後の加飾シートが破れたり、成形後の加飾シートの絵柄が上記一部の領域で歪むことがある。例えば、加飾成形品の表面形状や成形型の形状によっては、加飾シートの一部の領域が５０％～２００％の伸び率で伸長する。絵柄を有する加飾シートの一部の領域がこのような大きな伸び率で伸長すると、加飾シートの絵柄が顕著に歪むことがある。この結果、意図した意匠とは異なる意匠が加飾成形品に付与される場合がある。これを解決するために、加飾シートのサンプルや成形型の試作が繰り返される。迅速な意匠開発を行うために、加飾シートを作製する前に、加飾シートの意匠を評価することが求められ得る。 However, in the design development of decorative sheets, it is necessary to manufacture decorative sheet samples in order to verify the design, and to manufacture molds for manufacturing decorative molded products. Therefore, according to the number of designs to be developed, the number of decorative sheet samples and molds to be prototyped increases. This increases the burden on design development and lengthens the development period. Furthermore, depending on the surface shape of the decorative molded product and the shape of the molding surface of the molding die, when the decorative sheet is laminated on the surface of the resin molded product, a partial area of the decorative sheet is remarkably elongated. As a result, the molded decorative sheet may be torn, or the pattern of the molded decorative sheet may be distorted in the above partial area. For example, depending on the surface shape of the decorative molded product and the shape of the mold, a part of the decorative sheet is elongated at an elongation rate of 50% to 200%. When a part of the decorative sheet having a pattern is stretched at such a large elongation rate, the pattern of the decorative sheet may be significantly distorted. As a result, a design different from the intended design may be imparted to the decorative molded product. In order to solve this problem, trial production of decorative sheet samples and molds is repeated. In order to carry out rapid design development, it may be required to evaluate the design of the decorative sheet before manufacturing the decorative sheet.
　第１の開示は、以上の点を考慮してなされ、加飾成形品を作製する際の加飾シートの意匠開発を迅速に行うことが可能な、画像評価システム、画像評価方法、加飾シートのサンプルの製造方法および加飾シートの製造方法を提供することを目的とする。 The first disclosure is made in consideration of the above points, and an image evaluation system, an image evaluation method, and a decorative sheet that can quickly develop the design of a decorative sheet when producing a decorative molded product. An object of the present invention is to provide a sample manufacturing method and a decorative sheet manufacturing method.
　また、第２の開示は、以上の点を考慮してなされ、加飾成形品を作製する際の加飾シートの絵柄の変形を、成形型や加飾成形品を作製することなく評価可能にすることを目的とする。 In addition, the second disclosure is made in consideration of the above points, and the deformation of the pattern of the decorative sheet when producing the decorative molded product can be evaluated without producing a mold or a decorative molded product. intended to

　加飾成形品１は、例えば、移動体の内装部品や外装部品、建材の内装材や外装材、家電筐体として用いられる。移動体とは、例えば、自動車や鉄道車両、台車、船、飛行機、ヘリコプター、ドローン、ロボットである。図１に示すように、加飾成形品１は、成形部２と加飾シート３とを備えている。 The decorative molded product 1 is used, for example, as interior and exterior parts of moving bodies, interior and exterior materials of building materials, and home appliance housings. Mobile objects are, for example, automobiles, railroad vehicles, trucks, ships, airplanes, helicopters, drones, and robots. As shown in FIG. 1, a decorative molded product 1 includes a molded portion 2 and a decorative sheet 3. As shown in FIG.
　成形部２は、樹脂材料が成形された部品であり、例えば、後述するように、樹脂材料を射出成形することにより作製される。成形部２をなす樹脂材料は特に限定されない。成形部２をなす樹脂材料として、ポリカーボネート、ポリメタクリル酸メチル等のアクリル樹脂、ＡＢＳ（アクリロニトリル　ブタジエン　スチレン共重合体）、ポリプロピレンが例示される。成形部２は、透明でも、不透明でもよい。成形部２は、着色されていてもよい。 The molded part 2 is a part molded from a resin material, and is manufactured by, for example, injection molding a resin material as described later.

Examples of the resin material forming the molding portion 2 include polycarbonate, acrylic resin such as polymethyl methacrylate, ABS (acrylonitrile-butadiene-styrene copolymer), and polypropylene. Molded portion 2 may be transparent or opaque. Molded portion 2 may be colored.
　加飾シート３は、成形部２の表面の少なくとも一部を覆う。図示された例では、加飾シート３は、樹脂材料で作製された基材シート４に意匠層５や表面保護層６等を積層することにより作製される。基材シート４をなす樹脂材料として、ポリメタクリル酸メチル等のアクリル樹脂、ポリエチレンテレフタレート、塩化ビニル、ＡＢＳ（アクリロニトリル　ブタジエン　スチレン共重合体）、ポリカーボネート、ポリエチレンナフタレート、ポリスチレン、環状ポリオレフィン、ポリプロピレン等が例示される。例示した材料のシートを単層又は複数で用いてもよく、例えば、アクリル樹脂とＡＢＳを積層して用いてもよい。基材シート４は、透明でも不透明でもよい。基材シート４は着色されていてもよい。加飾シート３は、透明でもよく、不透明でもよい。 The decorative sheet 3 covers at least part of the surface of the molded portion 2. In the illustrated example, the decorative sheet 3 is produced by laminating a design layer 5, a surface protection layer 6, etc. on a base sheet 4 made of a resin material. Examples of the resin material forming the base sheet 4 include acrylic resin such as polymethyl methacrylate, polyethylene terephthalate, vinyl chloride, ABS (acrylonitrile-butadiene-styrene copolymer), polycarbonate, polyethylene naphthalate, polystyrene, cyclic polyolefin, and polypropylene. be done. Sheets of the exemplified materials may be used in a single layer or in multiple layers, for example, a laminate of acrylic resin and ABS may be used. The base sheet 4 may be transparent or opaque. The base sheet 4 may be colored. The decorative sheet 3 may be transparent or opaque.
　意匠層５は、例えば、色彩やパターン、図形、デザイン、絵、写真、キャラクター、マーク、ピクトグラム、文字や数字などの絵柄が形成された層、木、布、革、石、金属等の素材を表現する絵柄が形成された層や、内部に凹凸構造を有し奥行きのある立体感を呈する層である。意匠層５は、印刷によって形成されてもよいし、転写によって形成されてもよい。 The design layer 5 is, for example, a layer in which patterns such as colors, patterns, figures, designs, pictures, photographs, characters, marks, pictograms, letters and numbers are formed, and materials such as wood, cloth, leather, stone, and metal. It is a layer on which a pattern to be expressed is formed, or a layer that has a concave-convex structure inside and presents a three-dimensional effect with depth. The design layer 5 may be formed by printing or may be formed by transfer.
　表面保護層６は、加飾成形品１の最表面を形成する。表面保護層６は、耐擦傷性等を有する。表面保護層６は、例えば樹脂材料により作製される。表面保護層６をなす樹脂材料として、熱可塑性樹脂、熱硬化性樹脂、電離放射線硬化樹脂が例示される。 The surface protective layer 6 forms the outermost surface of the decorative molding 1. The surface protective layer 6 has scratch resistance and the like. The surface protective layer 6 is made of, for example, a resin material. Examples of the resin material forming the surface protective layer 6 include thermoplastic resins, thermosetting resins, and ionizing radiation curable resins.
　加飾シート３の構成は上述した例に限られない。例えば、加飾シート３は、紫外線吸収層、反射防止層、光拡散層、接着層、バッカー層、遮光パターン等の機能層を備えていてもよい。 The configuration of the decorative sheet 3 is not limited to the example described above. For example, the decorative sheet 3 may have functional layers such as an ultraviolet absorption layer, an antireflection layer, a light diffusion layer, an adhesive layer, a backer layer, and a light shielding pattern.
　このような加飾成形品１は、例えば、次のような方法で作製される。まず、図２に示すように、成形型１０を準備する。成形型１０は、加飾成形品１の形状に対応した形状を有している。成形型１０は、雌型１１および雄型１２を有している。雌型１１および雄型１２は、それぞれ、成形用のキャビティＣ（図４参照）となる空間を画定するキャビティ面１３、１４を有する。雌型１１には、キャビティＣ内の空気を排出するための吸引孔１５が設けられている。 Such a decorative molded product 1 is produced, for example, by the following method. First, as shown in FIG. 2, a mold 10 is prepared. The mold 10 has a shape corresponding to the shape of the decorative molded product 1 . Mold 10 has female mold 11 and male mold 12 . The female mold 11 and the male mold 12 respectively have cavity surfaces 13 and 14 that define a space that becomes a molding cavity C (see FIG. 4). The female die 11 is provided with a suction hole 15 for discharging the air in the cavity C. As shown in FIG.
　次に、図３に示すように、加飾シート３を雌型１１のキャビティ面１３に対面して配置し、シートクランプ１６等を用いて雌型１１に固定する。図示された例では、シートクランプ１６は平面視において枠状に形成されている。次に、ヒータ１７で加飾シート３を加熱して軟化させつつ、加飾シート３と雌型１１のキャビティ面１３との間の空気を、吸引孔１５を通じて排出する。これにより、軟化した加飾シート３が伸長して、キャビティ面１３に概ね沿った形状になる。このようにして、加飾シート３は予備成形される。 Next, as shown in FIG. 3, the decorative sheet 3 is placed facing the cavity surface 13 of the female mold 11 and fixed to the female mold 11 using a sheet clamp 16 or the like. In the illustrated example, the seat clamp 16 is formed in a frame shape in plan view. Next, while the decorative sheet 3 is heated by the heater 17 to be softened, the air between the decorative sheet 3 and the cavity surface 13 of the female mold 11 is discharged through the suction holes 15 . As a result, the softened decorative sheet 3 is elongated and formed into a shape generally along the cavity surface 13 . Thus, the decorative sheet 3 is preformed.
　次に、図４に示すように、雄型１２のキャビティ面１４を雌型１１のキャビティ面１３に対向させ、雄型１２を雌型１１に密着させ固定する。次に、雌型１１と雄型１２との間に形成されたキャビティＣに、加熱されて溶融した樹脂材料Ｒを充填する。樹脂材料Ｒは、成形部２をなす樹脂材料である。キャビティＣに加熱された樹脂材料Ｒが充填されることにより、加飾シート３は雌型１１のキャビティ面１３に対応した形状になる。このようにして、加飾シート３は成形される。同時に、成形部２も成形される。キャビティＣ内の樹脂材料Ｒが冷却して固化した後、成形型１０を開いて成形物を取り出し、必要に応じて加飾シート３の不要部分をトリミングする。以上により、加飾成形品１が作製される。以下、上記の加飾成形品の製造方法を第１の製造方法（いわゆるサーモジェクト工法）と称することがある。 Next, as shown in FIG. 4, the cavity surface 14 of the male mold 12 is opposed to the cavity surface 13 of the female mold 11, and the male mold 12 is brought into close contact with the female mold 11 and fixed. Next, the cavity C formed between the female mold 11 and the male mold 12 is filled with a resin material R that has been heated and melted. The resin material R is a resin material forming the molding portion 2 . By filling the cavity C with the heated resin material R, the decorative sheet 3 has a shape corresponding to the cavity surface 13 of the female mold 11 . Thus, the decorative sheet 3 is molded. At the same time, the molded portion 2 is also molded. After the resin material R in the cavity C is cooled and solidified, the molding die 10 is opened and the molding is taken out, and unnecessary portions of the decorative sheet 3 are trimmed as necessary. As described above, the decorative molded product 1 is produced. Hereinafter, the manufacturing method of the above-mentioned decorative molding may be referred to as the first manufacturing method (so-called Thermoject method).
　なお、加飾成形品１の製造方法は、図２乃至図４に示す方法に限られない。例えば、加飾シート３は、成形型１０に適用される前に、成形型１０とは別の予備成形型を用いて予備成形されてもよい。この場合、次のような方法で加飾成形品１を作製してもよい。すなわち、加熱した加飾シート３を予備成形型（図示せず）に沿って伸長させて、成形型１０の雌型１１のキャビティ面１３に概ね対応した形状に予備成形する。次に、予備成形された加飾シート３を、予備成形型から取り外し、図４に示すように成形型１０内に配置する。次に、キャビティＣに溶融した樹脂材料Ｒを充填する。キャビティＣ内の樹脂が冷却して固化した後、成形型１０を開いて成形物を取り出す。成形物を成形型１０で成形後あるいは成形前に、必要に応じて加飾シート３の不要部分をトリミングする。以上により、加飾成形品１が作製される。以下、上記の加飾成形品の製造方法を第２の製造方法（いわゆるフィルムインサート工法）と称することがある。なお、加飾成形品は、例示の第１の製造方法及び第２の製造方法以外の、第３の製造方法（例えばインモールド成形等の成形方法を利用した工法）を用いてもよい。 It should be noted that the method for manufacturing the decorative molded product 1 is not limited to the method shown in FIGS. For example, the decorative sheet 3 may be preformed using a preforming die different from the forming die 10 before being applied to the forming die 10 . In this case, the decorative molded product 1 may be produced by the following method. That is, the heated decorative sheet 3 is stretched along a preforming die (not shown) to preform into a shape generally corresponding to the cavity surface 13 of the female die 11 of the forming die 10 . Next, the preformed decorative sheet 3 is removed from the preforming mold and placed in the forming mold 10 as shown in FIG. Next, the cavity C is filled with a molten resin material R. After the resin in the cavity C is cooled and solidified, the molding die 10 is opened and the molding is taken out. After or before molding the molding with the molding die 10, unnecessary portions of the decorative sheet 3 are trimmed as required. As described above, the decorative molded product 1 is produced. Hereinafter, the manufacturing method of the above-mentioned decorative molding may be referred to as a second manufacturing method (so-called film insert method). The decorative molded product may be produced by a third manufacturing method (for example, a method using a molding method such as in-mold molding) other than the first manufacturing method and the second manufacturing method.
　次に、第１の実施形態による画像評価システム２０について説明する。この画像評価システム２０は、加飾成形品１を作製するための加飾シート３の画像を評価するためのシステムである。 Next, the image evaluation system 20 according to the first embodiment will be described. This image evaluation system 20 is a system for evaluating the image of the decorative sheet 3 for producing the decorative molded product 1 .
　画像評価システム
　図５Ａに示すように、画像評価システム２０は、第１端末３０と、第１端末３０から提供された複数の画像データを表示可能な第２端末５０とを備えている。また、画像評価システム２０は、画像データを加工する加工部６０を更に備えていてもよい。このうち第１端末３０は、加飾シート３の画像データを格納部４０に提供するように構成されていてもよい。また、格納部４０は、第１端末３０から提供された複数の画像データを保存するように構成されていてもよい。さらに、第２端末５０は、第１端末３０および格納部４０のうちの少なくとも一方に、加飾シート３の画像データを提供するように構成されていてもよい。 Image Evaluation System As shown in FIG. 5A, the image evaluation system 20 includes a first terminal 30 and a second terminal 50 capable of displaying a plurality of image data provided from the first terminal 30. FIG. The image evaluation system 20 may further include a processing section 60 that processes image data. Among these, the first terminal 30 may be configured to provide the image data of the decorative sheet 3 to the storage section 40 . Also, the storage unit 40 may be configured to store a plurality of image data provided from the first terminal 30 . Furthermore, the second terminal 50 may be configured to provide image data of the decorative sheet 3 to at least one of the first terminal 30 and the storage section 40 .
　ここで、第１端末３０および／または第２端末５０が提供する加飾シート３の画像データは、加飾シート３の二次元データであってもよく、加飾シート３の二次元データに加えて微細な表面構造（例えば、凹凸構造）に関するデータを含む三次元データであってもよい。例えば、第１端末３０および第２端末５０の一方が、加飾シート３の二次元データを提供し、その後、他方が表面に関するデータを提供し、格納部４０において二次元データと表面に関するデータとを統合することにより、格納部４０に三次元データが保存されるようにしてもよい。また、第１端末３０が提供する加飾シート３の画像データは、加飾シート３のサンプルをスキャナで取り込んで作成した画像データであってもよく、画像編集用のソフトウエアを用いて作成した画像データであってもよい。加飾シート３のサンプルの製造を行わず、画像編集用のソフトウエアを用いて作成された画像データを用いることにより、加飾シートの意匠開発をより迅速に行うことが可能となる。加飾シート３の画像データは、例えば、加飾成形前の加飾シートを示す画像データである。言い換えると、加飾シート３の画像データは、加飾成形による加飾シートの伸びが実質的に考慮されていない加飾シートの画像データである。 Here, the image data of the decorative sheet 3 provided by the first terminal 30 and/or the second terminal 50 may be two-dimensional data of the decorative sheet 3, and in addition to the two-dimensional data of the decorative sheet 3, It may also be three-dimensional data including data on a fine surface structure (for example, uneven structure). For example, one of the first terminal 30 and the second terminal 50 provides two-dimensional data of the decorative sheet 3, and then the other provides data about the surface. , the three-dimensional data may be stored in the storage unit 40 by integrating the . The image data of the decorative sheet 3 provided by the first terminal 30 may be image data created by scanning a sample of the decorative sheet 3 with a scanner, and may be created using image editing software. It may be image data. By using image data created using image editing software without manufacturing a sample of the decorative sheet 3, it is possible to develop the design of the decorative sheet more quickly. The image data of the decorative sheet 3 is, for example, image data representing the decorative sheet before the decorative molding. In other words, the image data of the decorative sheet 3 is the image data of the decorative sheet in which elongation of the decorative sheet due to decorative molding is not substantially considered.
　第１端末３０は、画像データの解像度の高さを変えた複数種類のデータを格納部４０に提供してもよい。これにより、意匠開発の段階に応じて解像度の異なるデータを画像データとして利用することができる。例えば、実際に加飾シート３を作製する際に使用する画像データよりも、解像度を低くした、加飾シート３の画像データ（説明の便宜上、「低解像度の画像データ」と呼ぶことがある）を格納部４０に提供し、意匠開発の初期段階では低解像度の画像データを用いてもよい。そして、実際に加飾シート３を作製する際に必要な解像度をもつ加飾シート３の画像データ（説明の便宜上、「高解像度の画像データ」と呼ぶことがある）を格納部４０に提供してもよく、意匠開発の初期段階以降では高解像度の画像データを用いてもよい。このように、意匠開発の段階に応じて画像データの解像度を変更することにより、加飾シートメーカーとその顧客との間で効率的にデジタル環境下でのコミュニケーションをすることができる。この場合、第１端末３０が格納部４０の提供する、低解像度の画像データの解像度は、例えば、１００ｄｐｉ以上３００ｄｐｉ以下であってもよく、一例として、約１５０ｄｐｉであってもよい。これにより、例えば、第２端末５０において、第２端末５０のユーザーが意匠を選択するために多数の画像データを表示させた場合であっても、第２端末５０への負荷を低減できる。また、第２端末５０のユーザーが、複数の低解像度の画像データをダウンロードしやすくなり、ユーザーの利便性が向上する。また、例えば、加飾成形品の形状に対応させるために、長さが１ｍを超えるような長尺フィルムに印刷するために画像を長尺サイズに構成した場合であっても、画像データの容量の増加が抑えられ各種機械への負荷を低減できる。 The first terminal 30 may provide the storage unit 40 with a plurality of types of data in which the resolution of the image data is changed. As a result, data with different resolutions can be used as image data according to the stage of design development. For example, image data of the decorative sheet 3 whose resolution is lower than that of the image data used when actually producing the decorative sheet 3 (for convenience of explanation, it may be referred to as “low-resolution image data”). is provided to the storage unit 40, and low-resolution image data may be used in the early stages of design development. Then, image data of the decorative sheet 3 having a resolution necessary for actually producing the decorative sheet 3 (for convenience of explanation, sometimes referred to as "high-resolution image data") is provided to the storage unit 40. High-resolution image data may be used after the initial stage of design development. In this way, by changing the resolution of the image data according to the stage of design development, it is possible to effectively communicate in a digital environment between the decorative sheet manufacturer and its customers. In this case, the resolution of the low-resolution image data provided by the storage unit 40 of the first terminal 30 may be, for example, 100 dpi or more and 300 dpi or less, and may be approximately 150 dpi, for example. As a result, for example, even when a large number of image data are displayed on the second terminal 50 in order for the user of the second terminal 50 to select a design, the load on the second terminal 50 can be reduced. In addition, it becomes easier for the user of the second terminal 50 to download a plurality of pieces of low-resolution image data, improving convenience for the user. In addition, for example, even if the image is configured in a long size in order to print on a long film with a length exceeding 1 m in order to correspond to the shape of the decorative molded product, the capacity of the image data can be suppressed and the load on various machines can be reduced.
　次に、第１端末３０、格納部４０、第２端末５０及び加工部６０について詳細に説明する。ここでは、まず、第１端末３０について説明する。 Next, the first terminal 30, storage section 40, second terminal 50 and processing section 60 will be described in detail. Here, first, the first terminal 30 will be described.
　（第１端末）
　第１端末３０は、表示部３１と、通信部３２と、記憶部３３と、処理部３４と、操作部３５とを有している。表示部３１は、画像データを表示するための構成である。これにより、第１端末３０は、画像データを表示可能である。表示部３１は、液晶ディスプレイ、プラズマディスプレイ、有機ＥＬディスプレイ等の任意のディスプレイを用いることができる。例えば、第１端末３０は、加飾シートを提供する加飾シートメーカーの端末である。 (first terminal)
The first terminal 30 has a display section 31 , a communication section 32 , a storage section 33 , a processing section 34 and an operation section 35 . The display unit 31 is configured to display image data. Thereby, the first terminal 30 can display the image data. Any display such as a liquid crystal display, a plasma display, or an organic EL display can be used as the display unit 31 . For example, the first terminal 30 is a terminal of a decorative sheet manufacturer that provides decorative sheets.
　通信部３２は、ネットワークを介して格納部４０等と第１端末３０との間で情報を送受信するためのインターフェースである。記憶部３３は、画像データ等のデータを記憶するための構成である。この記憶部３３は、例えばＲＯＭやＲＡＭなどのメモリーであってもよい。 The communication unit 32 is an interface for transmitting and receiving information between the storage unit 40 and the like and the first terminal 30 via the network. The storage unit 33 is configured to store data such as image data. The storage unit 33 may be a memory such as ROM or RAM, for example.
　処理部３４は、第１端末３０における必要な処理を実行するための構成である。この処理部３４は、例えば、所定のプログラムに基づいて動作するＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）により構成されていてもよい。 The processing unit 34 is a configuration for executing necessary processing in the first terminal 30 . The processing unit 34 may be configured by, for example, a CPU (Central Processing Unit) that operates based on a predetermined program.
　ここで、処理部３４は、シミュレーションにより、成形時に発生する加飾シート３の伸びを検証してもよい。加飾シート３を用いて作製される加飾成形品１は、高低差の大きい凹凸や貫通孔等を有する三次元形状をもっている。この高低差は、図２乃至４に示されるキャビティ面１３の高低差と捉えることができる。このため、加飾成形品１を作製した際に、三次元形状に追従する領域では加飾シート３に伸びが生じる。加飾シート３の伸びが大きい場合、加飾シート３が破けてしまう可能性がある。また、加飾シート３が破れなかった場合であっても、加飾シート３が伸びてしまうことにより、加飾シート３の絵柄が歪んでしまう可能性がある。この結果、加飾成形品１に付与される意匠と、目的とする意匠とが異なる場合がある。このような場合、加飾成形品１の表面形状や成形型の形状の設計を試行錯誤して修正することにより、加飾成形品１に付与される意匠を意図した意匠に近づけることができる。しかしながら、満足のいく加飾成形品１が作製されるまで加飾シートや成形型を作製し直すことは、加飾成形品１の作製にかかる時間およびコストの増大に繋がる。これに対して、処理部３４が、シミュレーションにより、成形時の加飾シート３の伸びを検証することにより、加飾シート３から加飾成形品１を作製できるか否かについて容易に判定することができるとともに、加飾シート３の絵柄の歪みを予め把握することができる。 Here, the processing unit 34 may verify the elongation of the decorative sheet 3 that occurs during molding by simulation. The decorative molded product 1 produced using the decorative sheet 3 has a three-dimensional shape having unevenness with a large height difference, through holes, and the like. This height difference can be regarded as the height difference of the cavity surface 13 shown in FIGS. Therefore, when the decorative molded product 1 is produced, the decorative sheet 3 is elongated in the area following the three-dimensional shape. If the decorative sheet 3 stretches too much, the decorative sheet 3 may tear. Further, even if the decorative sheet 3 is not torn, the pattern of the decorative sheet 3 may be distorted due to the stretching of the decorative sheet 3 . As a result, the design imparted to the decorative molded product 1 may differ from the desired design. In such a case, by modifying the design of the surface shape of the decorative molded product 1 and the shape of the mold through trial and error, the design imparted to the decorative molded product 1 can be brought closer to the intended design. However, remanufacturing the decorative sheet and mold until a satisfactory decorated molded product 1 is manufactured leads to an increase in the time and cost required to manufacture the decorated molded product 1 . On the other hand, the processing unit 34 can easily determine whether or not the decorative molded product 1 can be produced from the decorative sheet 3 by verifying the elongation of the decorative sheet 3 during molding by simulation. In addition, the distortion of the pattern of the decorative sheet 3 can be grasped in advance.
　この場合、第１端末３０は、加飾成形品１に関する三次元ＣＡＤデータに基づいて、成形時の加飾シート３の伸びを検証したシミュレーションデータを作成してもよい。シミュレーションデータの作成には、例えば、三次元ＣＡＤデータに基づいて生成される金型モデルのデータ、加飾シート３の物性データを用いてもよい。金型モデルのデータを用いてシミュレーションデータを作成する場合、まず、三次元ＣＡＤデータに基づいて成形に用いる金型モデルを作製する。次に、金型モデルを用いて、成形前後の加飾シート３の伸び量をシミュレーションしてシミュレーションデータを作成する。加飾シート３の伸び量に応じて加飾シート３の画像データの絵柄の成形後の位置を決定することによって、成形後の絵柄の状態をシミュレーションすることができる。そして、第１端末３０は、格納部４０を介して、シミュレーションデータを第２端末５０に提供してもよい。なお、処理部３４がシミュレーションをする際、例えば、上述した加飾成形品１の成形工法等が考慮されてもよい。加飾成形品１の成形工法によって異なる成形型が使用され得る。加飾成形品１の成形工法によって異なる加飾シート３の構成が使用され、その結果、加飾シート３の物性が変わり得る。このため、成形工法に応じた成形型や加飾シート３に基づいて、処理部３４が加飾シート３の伸びをシミュレーションしてもよい。これにより、加飾シート３の伸びをより正確に検証できる。 In this case, the first terminal 30 may create simulation data verifying the elongation of the decorative sheet 3 during molding based on the three-dimensional CAD data regarding the decorative molded product 1 . For creating simulation data, for example, mold model data generated based on three-dimensional CAD data and physical property data of the decorative sheet 3 may be used. When creating simulation data using mold model data, first, a mold model to be used for molding is created based on three-dimensional CAD data. Next, using a mold model, the elongation amount of the decorative sheet 3 before and after molding is simulated to create simulation data. By determining the post-molding position of the pattern of the image data of the decorative sheet 3 according to the amount of elongation of the decorative sheet 3, the state of the pattern after molding can be simulated. The first terminal 30 may then provide the simulation data to the second terminal 50 via the storage unit 40 . In addition, when the processing unit 34 performs the simulation, for example, the molding method of the decorative molded product 1 described above may be taken into consideration. Different molds can be used depending on the molding method of the decorative molded product 1 . Different configurations of the decorative sheet 3 are used depending on the molding method of the decorative molded product 1, and as a result, the physical properties of the decorative sheet 3 may vary. Therefore, the processing section 34 may simulate the elongation of the decorative sheet 3 based on the molding die and the decorative sheet 3 according to the molding method. Thereby, the elongation of the decorative sheet 3 can be verified more accurately.
　加飾成形品１の開発において、加飾シート３の意匠開発と加飾成形品１の開発とが並行して行われることがある。具体的には、加飾成形品１の仕様（例えば、形状）が決定する前に、加飾シート３の意匠開発が始まることがある。つまり、加飾シート３の意匠開発が進行する中で、加飾成形品１の形状が変更される場合がある。このような場合、シミュレーションデータの作成に用いる三次元ＣＡＤデータ（説明の便宜上、仮の三次元ＣＡＤデータと呼ぶことがある）と、変更された加飾成形品１の形状を表す三次元ＣＡＤデータ（説明の便宜上、修正後の三次元ＣＡＤデータと呼ぶことがある）とが異なる。加飾成形品１の開発が途上の段階においては仮の三次元ＣＡＤデータを用い、加飾成形品１の開発が完了した段階（例えば、加飾シート３のサンプルを評価する段階）においては仮の三次元ＣＡＤデータとは異なる、修正後の三次元ＣＡＤデータを用いてもよい。 In the development of the decorative molded product 1, the design development of the decorative sheet 3 and the development of the decorative molded product 1 may be carried out in parallel. Specifically, the design development of the decorative sheet 3 may begin before the specifications (for example, the shape) of the decorative molded product 1 are determined. In other words, the shape of the decorative molded product 1 may be changed as the design development of the decorative sheet 3 progresses. In such a case, three-dimensional CAD data used for creating simulation data (for convenience of explanation, it may be called temporary three-dimensional CAD data) and three-dimensional CAD data representing the changed shape of the decorative molded product 1 (for convenience of explanation, it may be referred to as corrected three-dimensional CAD data). Temporary three-dimensional CAD data is used at the stage of the development of the decorative molded product 1, and temporary You may use the three-dimensional CAD data after correction different from three-dimensional CAD data of .
　なお、加飾成形品１の三次元ＣＡＤデータは、格納部４０を介して、第２端末５０から第１端末３０に提供されてもよい。あるいは、加飾シート３を提供する側のユーザーが、加飾シート３を提供される側のユーザーに対して、加飾成形品１の形状等を提案する場合、提案する加飾成形品の三次元ＣＡＤデータが、第１端末３０の記憶部３３に予め保存されていてもよい。 The three-dimensional CAD data of the decorative molded product 1 may be provided from the second terminal 50 to the first terminal 30 via the storage unit 40. Alternatively, when the user who provides the decorative sheet 3 proposes the shape of the decorative molded product 1 to the user who receives the decorative sheet 3, the tertiary The original CAD data may be stored in the storage unit 33 of the first terminal 30 in advance.
　操作部３５は、第１端末３０のユーザーにより操作される入力装置であり、第１端末３０は、操作部３５に入力された操作に応じた処理を、処理部３４に実行させるように構成されている。 The operation unit 35 is an input device operated by the user of the first terminal 30, and the first terminal 30 is configured to cause the processing unit 34 to execute a process according to an operation input to the operation unit 35. ing.

　（格納部）
　格納部４０は、通信部４１と、記憶部４２と、処理部４３とを有している。通信部４１は、ネットワークを介して第１端末３０等と格納部４０との間で情報を送受信するためのインターフェースである。記憶部４２は、第１端末３０から提供された画像データ等を記憶するための構成である。この記憶部４２は、例えばＲＯＭやＲＡＭなどのメモリーであってもよい。 (storage unit)
The storage unit 40 has a communication unit 41 , a storage unit 42 and a processing unit 43 . The communication unit 41 is an interface for transmitting and receiving information between the first terminal 30 and the like and the storage unit 40 via a network. The storage unit 42 is configured to store image data and the like provided from the first terminal 30 . The storage unit 42 may be a memory such as ROM or RAM, for example.
　記憶部４２には、各々の画像データに関連付けされた様々な情報が１以上のデータテーブルに格納されていてもよい。この場合、格納部４０の記憶部４２には、画像データによってもたらされる意匠のコンセプトや、加飾シート３の製造条件に関するデータが格納されていてもよい。例えば、図５Ｂに示すように、各々の画像データの意匠（例えば絵柄や色）、加飾シートを用いて成形する方法（成形工法）、加飾シートの材料、加飾シートに関するカーボンフットプリント（ＣＦＰ）等に関する情報が、データテーブルに格納されていてもよい。これにより、第２端末５０を操作するユーザーが、画像データに関連付けされた情報（例えば、成形時に採用可能な成形工法）に基づいて、画像データを検索できるようになっていてもよい。なお、成形工法としては、例えば、インサート成形法、サーモジェクト成形法またはインモールド成形法が挙げられる。また、図示はしないが、加飾シート３の層構成、材料または厚み等に関する情報が、データテーブルに格納されていても良い。さらに、加飾成形品１を作製する際の加飾シート３の伸びに関する情報が、データテーブルに格納されていても良い。 Various information associated with each image data may be stored in one or more data tables in the storage unit 42 . In this case, the storage unit 42 of the storage unit 40 may store design concepts brought about by image data and data related to manufacturing conditions of the decorative sheet 3 . For example, as shown in FIG. 5B, the design of each image data (for example, pattern and color), the method of molding using the decorative sheet (molding method), the material of the decorative sheet, the carbon footprint of the decorative sheet ( CFP), etc. may be stored in the data table. Thereby, the user operating the second terminal 50 may be able to search for the image data based on the information associated with the image data (for example, the molding method that can be used during molding). Examples of the molding method include an insert molding method, a thermoject molding method, and an in-mold molding method. Although not shown, information about the layer structure, material, thickness, etc. of the decorative sheet 3 may be stored in a data table. Further, information regarding the elongation of the decorative sheet 3 when manufacturing the decorative molded product 1 may be stored in the data table.
　製造条件に関するデータを利用した一例として、例えば、成形工法ごとに、製造可能な加飾シートの仕様、加飾シートの製造数、加飾シートの製造納期、又は製造可能な加飾成形品１の形状等に関する情報が、データテーブルに格納されていてもよい。なお、「製造可能な加飾シートの仕様」としては、例えば、加飾シート３の層構成、絵柄、色、又は光沢感（グロス感若しくはマット感）といった質感等の情報が記載されていてもよい。また、「製造可能な加飾成形品１の形状」としては、成形時に加飾シートが伸びて破れることがないような加飾成形品１の高さＨ（図１参照）等の情報が記載されていてもよい。 As an example of using data on manufacturing conditions, for example, for each molding method, specifications of decorative sheets that can be manufactured, the number of decorative sheets to be manufactured, the manufacturing delivery date of decorative sheets, or the number of decorative molded products 1 that can be manufactured Information about the shape and the like may be stored in the data table.

Other examples of pattern-adjusted image data include image data in which patterns used for design expression are dark in color and image data in which patterns are light in color. Further examples of pattern-adjusted image data include image data with fine pattern definition and image data with coarse pattern definition used for design expression. Still another example of pattern-adjusted image data is image data with different patterns used for design expression. The first terminal 30 provides the image data selected by the user of the second terminal 50 and the pattern adjusted image data to the second terminal 50 . Thereby, as shown in FIG. 5F, a plurality of image data represented by manufacturable patterns are displayed on the second terminal 50 . The second terminal 50 may be configured to display a list of all image data having manufacturable structures. In addition, in FIG. 5F, illustration of the difference in definition is omitted for clarity of the drawing.

　製造条件に関するデータを利用した他の例として、例えば、図５Ｇに示すように、各画像データの意匠及び／又は成形工法ごとに、所定の領域ごとに表現できるパターン（例えば、細線の幅の大小、色の濃淡、精細度、パターンの種類）が、データテーブルに格納されていてもよい。なお、図５Ｇに示す例においては、画像データ番号１における組合せのみを図示している。図５Ｇの「Ａ部」は、任意の領域（例えば、後述する図５Ｈ及び図５ＩのＡ部）であってもよく、「その他」は、Ａ部以外の領域であってもよい。この場合、第２端末５０のユーザーは、特定の意匠に関する画像データ番号（例えば、「１番」）を選択する。そうすると、第１端末３０のユーザーは、記憶部４２に格納されたデータテーブルを参照する。次に、第１端末３０のユーザーは、上述したように、第１端末３０によって、画像データ番号「１番」のパターンの一部を製造可能な範囲で調整した、複数の画像データ（説明の便宜上、パターン調整された画像データと呼ぶことがある）を作成する。この場合、図５Ｈに示すように、画像データ番号「１番」の細分化「１ａ」のパターンでは、Ａ部の線幅が大きい画像データが作成される。一方、図５Ｉに示すように、画像データ番号「１番」の細分化「１ｃ」のパターンでは、Ａ部の線幅が小さい画像データが作成される。そして、第１端末３０は、第２端末５０のユーザーが選択した画像データ及びパターン調整された画像データを第２端末５０に提供する。これにより、第２端末５０上には、製造可能なパターンで表現された複数の画像データが表示される。第２端末５０は、製造可能な構造を有する全画像データを一覧表示できるように構成されていてもよい。そして、第２端末５０のユーザーは、表示された複数の画像データを閲覧しながら、製造可能な条件を満たしたパターンの画像データを選択できる。任意であるが、第２端末５０のユーザーは、製造可能なパターンで表現された画像データを参照する過程で、インサート成形法、サーモジェクト成形法またはインモールド成形法から、所望の成形法（例えば、インサート成形法）を選択してもよい。 As another example of using data related to manufacturing conditions, for example, as shown in FIG. , color intensity, definition, pattern type) may be stored in a data table.

In this case, the user of the second terminal 50 selects the image data number (for example, "No. 1") relating to the specific design. Then, the user of the first terminal 30 refers to the data table stored in the storage section 42 . Next, as described above, the user of the first terminal 30 uses the first terminal 30 to adjust a part of the pattern of the image data number "1" within a manufacturable range, and then a plurality of image data ( For the sake of convenience, this may be referred to as pattern-adjusted image data). In this case, as shown in FIG. 5H, in the subdivision pattern "1a" of the image data number "1", image data with a large line width in the A portion is created. On the other hand, as shown in FIG. 5I, in the subdivision pattern "1c" of the image data number "1", image data with a small line width in the A portion is created. The first terminal 30 then provides the image data selected by the user of the second terminal 50 and the pattern-adjusted image data to the second terminal 50 . As a result, a plurality of image data represented by manufacturable patterns are displayed on the second terminal 50 .

The texture information includes the size (two-dimensional size), height, sparseness and density of unevenness, glossiness (glossiness or matteness), and the like. In this case, the user of the second terminal 50 selects the image data number (for example, "No. 1"). Then, the user of the first terminal 30 refers to the data table stored in the storage section 42 . Next, the user of the first terminal 30 selects a plurality of image data (for convenience of explanation, texture (sometimes referred to as adjusted image data). The first terminal 30 provides the second terminal 50 with the image data selected by the user of the second terminal 50 and the texture-adjusted image data. As a result, as shown in FIG. 5K, image data expressed with manufacturable textures is displayed on the second terminal 50 . Note that the second terminal 50 may be configured to display a list of all image data having manufacturable structures. Then, the user of the second terminal 50 can select the image data of the pattern that satisfies the manufacturable conditions while viewing the displayed plurality of image data.

　（第２端末）
　第２端末５０は、表示部５１と、通信部５２と、記憶部５３と、処理部５４と、操作部５５とを有している。表示部５１は、画像データを表示するための構成である。表示部５１は、液晶ディスプレイ、プラズマディスプレイ、有機ＥＬディスプレイ等の任意の表示部を用いることができる。例えば、第２端末５０は、加飾シート３を提供されるユーザーの端末、又は加飾成形品１を提供されるユーザーの端末である。 (second terminal)
The second terminal 50 has a display section 51 , a communication section 52 , a storage section 53 , a processing section 54 and an operation section 55 . The display unit 51 is configured to display image data. Any display unit such as a liquid crystal display, a plasma display, an organic EL display, or the like can be used as the display unit 51 . For example, the second terminal 50 is the terminal of the user who is provided with the decorative sheet 3 or the terminal of the user who is provided with the decorative molding 1 .
　第２端末５０が画像データを表示する際の表示条件は、第１端末３０が画像データを表示する際の表示条件に基づいて決定されていることが好ましい。ここで、表示条件とは、画像データを表示するディスプレイの精細度、色および明るさを意味する。この場合、例えば、第１端末３０の表示部３１が液晶ディスプレイである場合、第２端末５０の表示部５１は、表示部３１と同一の液晶ディスプレイであってもよい。これにより、表示部５１に表示される画像データの表示態様を、表示部３１によって表示される画像データの表示態様に近づけることができる。このため、例えば画像データを加工する際に、加飾シート３を提供される側のユーザーが求める修正点を、加飾シート３を提供する側のユーザーに対して正確に伝えることができる。この結果、加飾シート３を提供される側のユーザーが、所望の画像データを容易に得ることができる。また、例えば、第１端末３０の表示部３１が液晶ディスプレイである場合、第２端末５０の表示部５１は、表示部３１と同一規格の色域に対応できる液晶ディスプレイであってもよい。 The display conditions when the second terminal 50 displays the image data are preferably determined based on the display conditions when the first terminal 30 displays the image data. Here, the display conditions mean the definition, color and brightness of the display that displays the image data. In this case, for example, when the display unit 31 of the first terminal 30 is a liquid crystal display, the display unit 51 of the second terminal 50 may be the same liquid crystal display as the display unit 31 . Thereby, the display mode of the image data displayed on the display unit 51 can be brought closer to the display mode of the image data displayed by the display unit 31 . Therefore, when processing image data, for example, correction points requested by the user who is provided with the decorative sheet 3 can be accurately communicated to the user who is provided with the decorative sheet 3 . As a result, the user who receives the decorative sheet 3 can easily obtain desired image data. Further, for example, when the display unit 31 of the first terminal 30 is a liquid crystal display, the display unit 51 of the second terminal 50 may be a liquid crystal display that can support the same standard color gamut as the display unit 31 .

　処理部５４は、第２端末５０における必要な処理を実行するための構成である。この処理部５４は、例えば、所定のプログラムに基づいて動作するＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）により構成されていてもよい。 The processing unit 54 is a configuration for executing necessary processing in the second terminal 50 . The processing unit 54 may be configured by, for example, a CPU (Central Processing Unit) that operates based on a predetermined program.
　操作部５５は、第２端末５０のユーザーにより操作される入力装置であり、第２端末５０は、操作部５５に入力された操作に応じた処理を、処理部５４に実行させるようになっている。 The operation unit 55 is an input device operated by the user of the second terminal 50, and the second terminal 50 causes the processing unit 54 to execute processing according to the operation input to the operation unit 55. there is

　（加工部）
　加工部６０は、画像データに対して、所定の加工処理を施すための構成である。加工部６０は、第１端末３０及び／又は第２端末５０からの信号に基づいて、製造条件を満たすように、画像データの絵柄、色及び質感のうち少なくとも１つを変更してもよい。例えば、加工部６０は、第１端末３０及び／又は第２端末５０からの信号に基づいて、画像データの絵柄、色又は光沢感（グロス感若しくはマット感）等を変更できるようになっていてもよい。また、画像データが三次元データである場合、加工部６０は、第１端末３０及び／又は第２端末５０からの信号に基づいて、加飾シート３の表面に形成された凹凸の高さ等を変更できるように構成されていてもよい。この加工部６０は、例えば、所定のプログラムに基づいて動作するＣＰＵにより構成されていてもよい。 (process section)
The processing unit 60 is configured to perform predetermined processing on image data. Based on the signal from the first terminal 30 and/or the second terminal 50, the processing section 60 may change at least one of the pattern, color and texture of the image data so as to satisfy the manufacturing conditions. For example, the processing unit 60 can change the pattern, color, or glossiness (glossiness or matteness) of the image data based on signals from the first terminal 30 and/or the second terminal 50. good too.

　なお、加工部６０は、第１端末３０と一体化していてもよい。この場合、第１端末３０を操作するユーザーが、画像データを変更することができる。すなわち、加飾シート３を提供する側のユーザーが、第１端末３０上で画像データを変更できる。また、加工部６０は、第２端末５０と一体化していてもよい。この場合、第２端末５０を操作するユーザーが、画像データを変更することができる。すなわち、加飾シート３を提供される側のユーザーが、第２端末５０上で画像データを変更できる。この場合、加飾シート３を提供される側のユーザーが画像データを変更できるため、加飾シート３を提供される側のユーザーが、所望の画像データを容易に得ることができる。あるいは、加飾シート３を提供する側のユーザーおよび加飾シート３を提供される側のユーザーが、それぞれ加工部６０にアクセス可能になっていてもよい。 Note that the processing unit 60 may be integrated with the first terminal 30. In this case, the user operating the first terminal 30 can change the image data. That is, the user who provides the decorative sheet 3 can change the image data on the first terminal 30 . Moreover, the processing unit 60 may be integrated with the second terminal 50 . In this case, the user operating the second terminal 50 can change the image data. That is, the user who receives the decorative sheet 3 can change the image data on the second terminal 50 . In this case, since the user who receives the decorative sheet 3 can change the image data, the user who receives the decorative sheet 3 can easily obtain the desired image data. Alternatively, the user who provides the decorative sheet 3 and the user who receives the decorative sheet 3 may each access the processing unit 60 .

　画像評価方法
　次に、第１の実施形態による作用について説明する。ここでは、まず、加飾シート３から加飾成形品１を作製する前に、加飾シート３の画像を評価する画像評価方法について、図６により説明する。 Image Evaluation Method Next, the operation of the first embodiment will be described. Here, first, an image evaluation method for evaluating the image of the decorative sheet 3 before producing the decorative molded product 1 from the decorative sheet 3 will be described with reference to FIG.
　まず、格納部４０が、加飾シート３の画像データを第１端末３０から取得する（図６のステップＳ１）。この際、第１端末３０の記憶部３３に保存された画像データが、格納部４０に提供される（図６のステップＳ１１）。そして、当該画像データが、格納部４０の記憶部４２に保存される。このとき、格納部４０の記憶部４２は、第１端末３０から提供された複数の画像データを、所定の特徴毎にグループ化して保存していてもよい。また、格納部４０には、各々の画像データに関連付けされた様々な情報が１以上のデータテーブルに格納されてもよい（図５Ｂ等参照）。この場合、格納部４０の記憶部４２には、加飾シート３の製造条件に関するデータが格納されてもよい。 First, the storage unit 40 acquires the image data of the decorative sheet 3 from the first terminal 30 (step S1 in FIG. 6). At this time, the image data stored in the storage unit 33 of the first terminal 30 is provided to the storage unit 40 (step S11 in FIG. 6). Then, the image data is stored in the storage section 42 of the storage section 40 . At this time, the storage unit 42 of the storage unit 40 may group and store the plurality of image data provided from the first terminal 30 for each predetermined feature. Various information associated with each image data may be stored in one or more data tables in the storage unit 40 (see FIG. 5B, etc.). In this case, the storage section 42 of the storage section 40 may store data relating to manufacturing conditions for the decorative sheet 3 .
　次に、格納部４０が、第２端末５０からの信号に基づいて、画像データを第２端末５０に提供する（図６のステップＳ２）。この際、まず、第２端末５０を操作するユーザーが、第２端末５０の操作部５５を操作することにより、所望の条件を入力する。例えば、第２端末５０を操作するユーザーが、例えば、「スポーティー」といったコンセプトに対応する画像データを第２端末５０に表示させたい場合、第２端末５０の操作部５５を操作することにより、当該条件を入力する。これにより、第２端末５０から信号が送信され、格納部４０の処理部４３が、当該コンセプトに対応する画像データを第２端末５０に送信する。なお、この際、複数の画像データが、第２端末５０に送信されてもよい。このようにして、第２端末５０が、格納部４０から画像データを取得する（図６のステップＳ２１）。第２端末５０を操作するユーザーが、画像データの絵柄、色、コンセプト、対応工法、材料、又はカーボンフットプリント（ＣＦＰ）等に関する条件を入力することにより、画像データを検索してもよい。また、格納部４０に格納された加飾シート３の製造条件等に関するデータテーブルが参照されることにより、第２端末５０のユーザーは、画像データを取得してもよい。この場合、第２端末５０のユーザーは、特定の意匠に関する画像データ番号（例えば、図５Ｂに示す「１番」等）を選択する。そうすると、第１端末３０のユーザーは、記憶部４２に格納されたデータテーブルを参照する。次に、第１端末３０のユーザーは、第１端末３０によって、画像データ番号「１番」の色等を製造可能な範囲で調整した、複数の画像データを作成する。そして、第１端末３０は、第２端末５０のユーザーが選択した画像データ及び色調整された画像データ等を第２端末５０に提供する。このようにして、第２端末５０上に、製造可能なパターンで表現された複数の画像データが表示されてもよい。このように、第２端末５０のユーザーは、コンセプトに合う画像データを選択し、その後、派生した絵柄をもつ画像データ、色が変更された画像データ、質感が調整された画像データを閲覧する。これにより、第２端末５０のユーザーの作業効率を高めることができる。デジタル環境下では画像データの絵柄、色、質感等が自由に変更できてしまう一方で、実際には印刷によって再現できない画像データが作成されてしまうことがある。これに対して、製造条件に関する情報を利用して製造可能な条件を満たす、絵柄、色および質感をもつ画像データを提供することにより、画像データを提供する者と画像データを評価する者との間で行われる意匠開発をより迅速かつ効率的に行うことが可能となる。 Next, the storage unit 40 provides image data to the second terminal 50 based on the signal from the second terminal 50 (step S2 in FIG. 6). At this time, first, the user who operates the second terminal 50 inputs desired conditions by operating the operation unit 55 of the second terminal 50 . For example, when the user operating the second terminal 50 wants to display image data corresponding to a concept such as "sporty" on the second terminal 50, the user operates the operation unit 55 of the second terminal 50 to display the Enter your conditions. A signal is thereby transmitted from the second terminal 50 , and the processing unit 43 of the storage unit 40 transmits image data corresponding to the concept to the second terminal 50 . At this time, multiple pieces of image data may be transmitted to the second terminal 50 . In this manner, the second terminal 50 acquires image data from the storage unit 40 (step S21 in FIG. 6). A user who operates the second terminal 50 may search for image data by inputting conditions related to the pattern, color, concept, corresponding construction method, material, or carbon footprint (CFP) of the image data. Further, the user of the second terminal 50 may obtain image data by referring to a data table regarding manufacturing conditions of the decorative sheet 3 stored in the storage unit 40 . In this case, the user of the second terminal 50 selects an image data number related to a specific design (for example, "No. 1" shown in FIG. 5B). Then, the user of the first terminal 30 refers to the data table stored in the storage section 42 . Next, the user of the first terminal 30 uses the first terminal 30 to create a plurality of image data in which the color of the image data number “1” is adjusted within a manufacturable range. Then, the first terminal 30 provides the second terminal 50 with the image data selected by the user of the second terminal 50, the color-adjusted image data, and the like. In this manner, a plurality of image data represented by manufacturable patterns may be displayed on the second terminal 50 . In this way, the user of the second terminal 50 selects image data that matches the concept, and then browses image data with derived patterns, image data with changed colors, and image data with textures adjusted. Thereby, the work efficiency of the user of the second terminal 50 can be improved. In a digital environment, the pattern, color, texture, etc. of image data can be freely changed, but image data that cannot actually be reproduced by printing may be created. On the other hand, by providing image data having patterns, colors and textures that satisfy the manufacturable conditions using the information on the manufacturing conditions, the person who provides the image data and the person who evaluates the image data can meet each other. Design development between companies can be done more quickly and efficiently.
　第２端末５０が、格納部４０から画像データを取得する工程（図６のステップＳ２１）の前後で、画像データの解像度を変更してもよい。例えば、第２端末５０に提供する画像データの解像度が、第２端末５０に提供する後述する第１加工データの解像度よりも低くてもよい。言い換えれば、第２端末５０が格納部４０から画像データを取得する前、つまり、第２端末５０のユーザーが多数の絵柄の中から特定の絵柄を選択する段階では、上述のように低解像度の画像データを用いてもよい。第２端末５０が格納部４０から画像データを取得した後、つまり、第２端末５０のユーザーが特定の絵柄を評価する段階では、上述のように高解像度の画像データを用いてもよい。さらに、製造条件に関する情報を利用して製造可能な条件を満たす、絵柄、色および質感をもつ画像データを提供する場合にも、高解像度の画像データを用いてもよい。このように、意匠開発の段階に応じて画像データの解像度を変更することにより、加飾シートメーカーとその顧客との間で効率的にデジタル環境下でのコミュニケーションをすることができる。 The second terminal 50 may change the resolution of the image data before and after the step of acquiring the image data from the storage unit 40 (step S21 in FIG. 6). For example, the resolution of the image data provided to the second terminal 50 may be lower than the resolution of first processed data provided to the second terminal 50, which will be described later. In other words, before the second terminal 50 acquires the image data from the storage unit 40, that is, at the stage where the user of the second terminal 50 selects a specific pattern from a large number of patterns, the low-resolution image data is displayed as described above. Image data may also be used. After the second terminal 50 acquires the image data from the storage unit 40, that is, at the stage where the user of the second terminal 50 evaluates a specific pattern, high-resolution image data may be used as described above. Furthermore, high-resolution image data may be used when providing image data with patterns, colors, and textures that satisfy manufacturing conditions using information on manufacturing conditions. In this way, by changing the resolution of the image data according to the stage of design development, it is possible to effectively communicate in a digital environment between the decorative sheet manufacturer and its customers.
　次いで、格納部４０が、画像データの評価結果を第２端末５０から取得する（図６のステップＳ３）。この際、まず、第２端末５０を操作するユーザーが、第２端末５０に提供された画像データを閲覧するとともに、当該画像データを評価する。そして、画像データを閲覧したユーザーが、第２端末５０の操作部５５を操作することにより、画像データの評価結果を入力する（図６のステップＳ２２）。 Next, the storage unit 40 acquires the image data evaluation result from the second terminal 50 (step S3 in FIG. 6). At this time, first, the user operating the second terminal 50 views the image data provided to the second terminal 50 and evaluates the image data. Then, the user who browsed the image data inputs the evaluation result of the image data by operating the operation unit 55 of the second terminal 50 (step S22 in FIG. 6).
　第２端末５０を操作するユーザーは、画像データを閲覧した際に、当該画像データの絵柄が満足のいく絵柄であるか否かを判定してもよい。画像データの絵柄が満足のいく絵柄である場合、画像データを閲覧したユーザーは、第２端末５０の操作部５５を操作することにより、評価結果として、画像データの絵柄が満足のいく絵柄である旨を入力してもよい。 The user who operates the second terminal 50 may determine whether or not the design of the image data is satisfactory when viewing the image data. When the picture of the image data is a satisfactory picture, the user who browsed the image data operates the operation unit 55 of the second terminal 50 to obtain an evaluation result indicating that the picture of the image data is a satisfactory picture. You can enter a statement.
　一方、画像データの絵柄が満足のいく絵柄でない場合、画像データを閲覧したユーザーは、第２端末５０の操作部５５を操作することにより、評価結果として、例えば、画像データの絵柄の色や形状等の変更を希望する旨を入力してもよい。なお、評価された画像データが、加飾シート３の絵柄だけでなく表面の凹凸に関する情報をもつ三次元データである場合、凹凸の高さ等の変更を希望する旨を入力してもよい。このようにして、第２端末５０から信号が送信され、格納部４０に評価結果が送信される。そして、格納部４０が、第２端末５０から評価結果を取得する（図６のステップＳ３）。 On the other hand, if the pattern of the image data is not satisfactory, the user who browsed the image data operates the operation unit 55 of the second terminal 50 to obtain, for example, the color and shape of the pattern of the image data as an evaluation result. You may also enter a request for changes such as If the evaluated image data is three-dimensional data containing not only the pattern of the decorative sheet 3 but also information about surface irregularities, it is possible to input a request to change the height of the irregularities. Thus, a signal is transmitted from the second terminal 50 and an evaluation result is transmitted to the storage unit 40 . Then, the storage unit 40 acquires the evaluation result from the second terminal 50 (step S3 in FIG. 6).
　次に、格納部４０から第１端末３０に評価結果が送信され（図６のステップＳ４）、第１端末３０が、評価結果を取得する（図６のステップＳ１２）。 Next, the evaluation result is transmitted from the storage unit 40 to the first terminal 30 (step S4 in FIG. 6), and the first terminal 30 acquires the evaluation result (step S12 in FIG. 6).
　ここで、画像データの評価結果に基づいて、加工部６０によって画像データを加工することにより、第１加工データを作成してもよい。すなわち、第２端末５０を操作するユーザーの判定が、画像データの絵柄が満足のいく絵柄でないといった判定であった場合（図６のステップＳ１３のＮＯ）、加工部６０によって画像データを加工することにより、第１加工データを作成してもよい（図６のステップＳ３１）。この場合、例えば第１端末３０を操作するユーザーが加工部６０を操作することにより、画像データの絵柄の色や形状を加工してもよい。このとき、加工部６０は、第２端末からの信号に基づいて、加飾シート３の製造条件を満たすように、画像データの絵柄、色及び質感のうち少なくとも１つを変更してもよい。なお、上述した画像データの絵柄が満足のいく絵柄であった場合（図６のステップＳ１３のＹＥＳ）、当該画像データをもつ加飾シート３を、加飾成形品１を作製する際に使用する加飾シート３として仮決定してもよい。 Here, the first processed data may be created by processing the image data by the processing unit 60 based on the evaluation result of the image data. That is, if the judgment of the user operating the second terminal 50 is that the pattern of the image data is not satisfactory (NO in step S13 of FIG. 6), the processing unit 60 processes the image data. (Step S31 in FIG. 6). In this case, for example, the user who operates the first terminal 30 may operate the processing unit 60 to process the color and shape of the pattern of the image data. At this time, the processing unit 60 may change at least one of the pattern, color, and texture of the image data based on the signal from the second terminal so as to satisfy the manufacturing conditions for the decorative sheet 3 . In addition, when the pattern of the image data described above is a satisfactory pattern (YES in step S13 of FIG. 6), the decorative sheet 3 having the image data is used when producing the decorative molded product 1. The decorative sheet 3 may be tentatively determined.
　加工部６０によって第１加工データを作成した場合、格納部４０が、作成された第１加工データを加工部６０から取得する（図６のステップＳ５）。この際、加工部６０が作成した第１加工データが、格納部４０に提供される（図６のステップＳ３２）。そして、当該第１加工データが、格納部４０の記憶部４２に保存される。 When the processing unit 60 creates the first processed data, the storage unit 40 acquires the created first processed data from the processing unit 60 (step S5 in FIG. 6). At this time, the first processed data created by the processing unit 60 is provided to the storage unit 40 (step S32 in FIG. 6). Then, the first processed data is stored in the storage section 42 of the storage section 40 .
　次に、格納部４０が、第１加工データを第２端末５０に提供する（図６のステップＳ６）。この際、格納部４０の処理部４３が、第１加工データを第２端末５０に送信する。このようにして、第２端末５０が、格納部４０から第１加工データを取得する（図６のステップＳ２３）。 Next, the storage unit 40 provides the first processed data to the second terminal 50 (step S6 in FIG. 6). At this time, the processing unit 43 of the storage unit 40 transmits the first processed data to the second terminal 50 . Thus, the second terminal 50 acquires the first processed data from the storage unit 40 (step S23 in FIG. 6).
　次いで、格納部４０が、第１加工データの評価結果を第２端末５０から取得する（図６のステップＳ７）。この際、まず、第２端末５０を操作するユーザーが、画像データを評価した場合と同様に、第２端末５０に提供された第１加工データを閲覧するとともに、当該第１加工データを評価する。そして、第１加工データを閲覧したユーザーが、第２端末５０の操作部５５を操作することにより、第１加工データの評価結果を入力する（図６のステップＳ２４）。そして、格納部４０が、第２端末５０から評価結果を取得する（図６のステップＳ７）。 Next, the storage unit 40 acquires the evaluation result of the first processed data from the second terminal 50 (step S7 in FIG. 6). At this time, first, the user operating the second terminal 50 browses the first processed data provided to the second terminal 50 and evaluates the first processed data in the same manner as when evaluating the image data. . Then, the user who browsed the first processed data inputs the evaluation result of the first processed data by operating the operation unit 55 of the second terminal 50 (step S24 in FIG. 6). Then, the storage unit 40 acquires the evaluation result from the second terminal 50 (step S7 in FIG. 6).
　次に、格納部４０から第１端末３０に評価結果が送信され（図６のステップＳ８）、画像データの評価結果を取得した場合と同様に、第１端末３０が、評価結果を取得する（図６のステップＳ１２）。 Next, the evaluation result is transmitted from the storage unit 40 to the first terminal 30 (step S8 in FIG. 6), and the first terminal 30 acquires the evaluation result ( Step S12 in FIG. 6).
　その後、第２端末５０を操作するユーザーの判定が、第１加工データの絵柄が満足のいく絵柄であるといった判定になるまで、上述した図６のステップＳ１３、Ｓ３１、Ｓ３２、Ｓ５、Ｓ６、Ｓ２３、Ｓ２４、Ｓ７、Ｓ８、Ｓ１２に示す工程が繰り返される。なお、第２端末５０を操作するユーザーの判定が、第１加工データの絵柄が満足のいく絵柄であるといった判定にならない場合には、上述した図６のステップＳ２からの工程を繰り返し、新たな画像データの絵柄を評価してもよい。 Thereafter, steps S13, S31, S32, S5, S6, and S23 in FIG. , S24, S7, S8 and S12 are repeated. It should be noted that if the determination by the user who operates the second terminal 50 does not result in the determination that the pattern of the first processed data is a satisfactory pattern, the steps from step S2 in FIG. You may evaluate the pattern of image data.
　そして、加飾成形品１を作製する際に使用する加飾シート３が仮決定される。 Then, the decorative sheet 3 to be used when manufacturing the decorative molded product 1 is tentatively determined.
　次に、加飾シート３の画像を、加飾成形品１の状態で評価する画像評価方法について、図７により説明する。 Next, an image evaluation method for evaluating the image of the decorative sheet 3 in the state of the decorative molded product 1 will be described with reference to FIG.
　この際、まず、図６に示す方法により、加飾成形品１を作製する際に使用する加飾シート３を決定する。 At this time, first, the decorative sheet 3 to be used when manufacturing the decorative molded product 1 is determined by the method shown in FIG.
　また、格納部４０が、加飾シート３を用いて作製される加飾成形品１に関する三次元ＣＡＤデータを第２端末５０から取得する（図７のステップＳ５１）。この際、第２端末５０の記憶部５３に保存された三次元ＣＡＤデータが、格納部４０に送信される（図７のステップＳ７１）。そして、当該三次元ＣＡＤデータが、格納部４０の記憶部４２に保存される。第２端末５０から取得する三次元ＣＡＤデータは、仮の三次元ＣＡＤデータであってもよいし、修正後の三次元ＣＡＤデータであってもよい。なお、三次元ＣＡＤデータが仮の三次元ＣＡＤデータである場合、後の工程の中（例えば、図７のステップＳ６５以降）で第２端末５０から改めて修正後の三次元ＣＡＤデータを取得してもよい。これにより、加飾シート３の意匠開発と加飾成形品１の開発とを並行して行うことができる。 Also, the storage unit 40 acquires the three-dimensional CAD data regarding the decorative molded product 1 produced using the decorative sheet 3 from the second terminal 50 (step S51 in FIG. 7). At this time, the three-dimensional CAD data stored in the storage unit 53 of the second terminal 50 is transmitted to the storage unit 40 (step S71 in FIG. 7). Then, the three-dimensional CAD data is stored in the storage section 42 of the storage section 40 . The three-dimensional CAD data acquired from the second terminal 50 may be provisional three-dimensional CAD data or corrected three-dimensional CAD data. If the three-dimensional CAD data is provisional three-dimensional CAD data, the corrected three-dimensional CAD data is acquired again from the second terminal 50 in a later process (for example, after step S65 in FIG. 7). good too. Thereby, design development of the decorative sheet 3 and development of the decorative molding 1 can be performed in parallel.

　次いで、第１端末３０によって、三次元ＣＡＤデータに基づいて成形時の加飾シート３の伸びを検証したシミュレーションデータを作成する（図７のステップＳ６２）。この際、まず、三次元ＣＡＤデータに基づいて成形型１０を決定し、決定された成形型１０の三次元形状を表す成形型データを生成する。次に、成形型データに基づいて、加飾シート３を成形した場合におけるシミュレーションデータを作成する。そして、作成されたシミュレーションデータは、第１端末３０の記憶部３３に保存される。なお、加飾シート３を提供する側のユーザーが、加飾シート３を提供される側のユーザーに対して、加飾成形品１の形状等を提案する場合もある。この場合、上述した図７のステップＳ７１、Ｓ５１、Ｓ５２、Ｓ６１に示す工程が行われることなく、第１端末３０が、記憶部３３に予め保存された三次元ＣＡＤデータに基づいて、加飾シート３の伸びを検証したシミュレーションデータを作成してもよい。 Next, the first terminal 30 creates simulation data verifying the elongation of the decorative sheet 3 during molding based on the three-dimensional CAD data (step S62 in FIG. 7). At this time, first, the molding die 10 is determined based on the three-dimensional CAD data, and molding die data representing the three-dimensional shape of the determined molding die 10 is generated. Next, based on the mold data, simulation data for molding the decorative sheet 3 is created. The created simulation data is stored in the storage unit 33 of the first terminal 30 . In some cases, the user who provides the decorative sheet 3 proposes the shape of the decorative molded product 1 to the user who receives the decorative sheet 3 . In this case, the processes shown in steps S71, S51, S52, and S61 of FIG. You may create the simulation data which verified the extension of 3.
　次に、格納部４０が、作成されたシミュレーションデータを第１端末３０から取得する（図７のステップＳ５３）。この際、第１端末３０の記憶部３３に保存されたシミュレーションデータが、格納部４０に提供される（図７のステップＳ６３）。そして、当該シミュレーションデータが、格納部４０の記憶部４２に保存される。 Next, the storage unit 40 acquires the created simulation data from the first terminal 30 (step S53 in FIG. 7). At this time, the simulation data stored in the storage unit 33 of the first terminal 30 is provided to the storage unit 40 (step S63 in FIG. 7). Then, the simulation data is stored in the storage section 42 of the storage section 40 .
　次いで、格納部４０が、シミュレーションデータを第２端末５０に提供する（図７のステップＳ５４）。この際、格納部４０の処理部４３が、シミュレーションデータを第２端末５０に送信する。このようにして、第２端末５０が、格納部４０からシミュレーションデータを取得する（図７のステップＳ７２）。 Next, the storage unit 40 provides the simulation data to the second terminal 50 (step S54 in FIG. 7).

At this time, first, the user operating the second terminal 50 views the simulation data provided to the second terminal 50 and evaluates the simulation data. Then, the user who browsed the simulation data inputs the evaluation result of the simulation data by operating the operation unit 55 of the second terminal 50 (step S73 in FIG. 7).
　第２端末５０を操作するユーザーは、シミュレーションデータを閲覧した際に、当該シミュレーションデータの絵柄が満足のいく絵柄であるか否かを判定してもよい。シミュレーションデータの絵柄が満足のいく絵柄である場合、シミュレーションデータを閲覧したユーザーは、第２端末５０の操作部５５を操作することにより、評価結果として、シミュレーションデータの絵柄が満足のいく絵柄である旨を入力してもよい。 The user operating the second terminal 50 may determine whether or not the design of the simulation data is satisfactory when viewing the simulation data. When the pattern of the simulation data is a satisfactory pattern, the user who browsed the simulation data operates the operation unit 55 of the second terminal 50 to obtain an evaluation result that the pattern of the simulation data is a satisfactory pattern. You can enter a statement.
　一方、シミュレーションデータの絵柄が満足のいく絵柄でない場合、シミュレーションデータを閲覧したユーザーは、第２端末５０の操作部５５を操作することにより、評価結果として、例えば、シミュレーションデータの絵柄の色や形状等の変更を希望する旨を入力してもよい。なお、上述した画像データが、加飾シート３の絵柄だけでなく表面の凹凸に関する情報をもつ三次元データである場合、シミュレーションデータを評価する際に、評価結果として、凹凸の高さ等の変更を希望する旨を入力してもよい。このようにして、第２端末５０から信号が送信され、格納部４０に評価結果が送信される。そして、格納部４０が、第２端末５０から評価結果を取得する（図７のステップＳ５５）。 On the other hand, if the pattern of the simulation data is not a satisfactory pattern, the user who browsed the simulation data operates the operation unit 55 of the second terminal 50 to obtain, for example, the color and shape of the pattern of the simulation data as an evaluation result. You may also enter a request for changes such as If the image data described above is three-dimensional data having information about not only the pattern of the decorative sheet 3 but also the unevenness of the surface, when evaluating the simulation data, changes in the height of the unevenness, etc. You may enter that you would like to Thus, a signal is transmitted from the second terminal 50 and an evaluation result is transmitted to the storage unit 40 . Then, the storage unit 40 acquires the evaluation result from the second terminal 50 (step S55 in FIG. 7).
　次に、格納部４０から第１端末３０に評価結果が送信され（図７のステップＳ５６）、第１端末３０が、評価結果を取得する（図７のステップＳ６４）。 Next, the evaluation result is transmitted from the storage unit 40 to the first terminal 30 (step S56 in FIG. 7), and the first terminal 30 acquires the evaluation result (step S64 in FIG. 7).
　ここで、シミュレーションデータの評価結果に基づいて、加工部６０によって画像データを加工することにより、第２加工データを作成してもよい。すなわち、第２端末５０を操作するユーザーの判定が、シミュレーションデータの絵柄が満足のいく絵柄でないといった判定であった場合（図７のステップＳ６５のＮＯ）、加工部６０によって画像データを加工することにより、第２加工データを作成してもよい（図７のステップＳ８１）。この場合、例えば第１端末３０を操作するユーザーが加工部６０を操作することにより、画像データの絵柄の色や形状を加工してもよい。加工された絵柄の決定において、シミュレーションデータが利用され得る。これにより、再びシミュレーションデータを作成することを省くことができ、意匠開発を迅速に行うことができる。なお、上述したシミュレーションデータの絵柄が満足のいく絵柄であった場合（図７のステップＳ６５のＹＥＳ）、当該画像データをもつ加飾シート３を、加飾成形品１を作製する際に使用する加飾シート３として最終決定してもよい。 Here, the second processed data may be created by processing the image data by the processing unit 60 based on the evaluation result of the simulation data. That is, if the judgment of the user operating the second terminal 50 is that the pattern of the simulation data is not a satisfactory pattern (NO in step S65 of FIG. 7), the processing unit 60 processes the image data. (step S81 in FIG. 7). In this case, for example, the user who operates the first terminal 30 may operate the processing unit 60 to process the color and shape of the pattern of the image data. Simulation data may be used in determining the processed pattern. As a result, it is possible to omit creating simulation data again, and it is possible to quickly develop a design. In addition, when the pattern of the simulation data described above is a satisfactory pattern (YES in step S65 of FIG. 7), the decorative sheet 3 having the image data is used when producing the decorative molded product 1. A final decision may be made as the decorative sheet 3 .
　加工部６０によって第２加工データを作成した場合、格納部４０が、作成された第２加工データを加工部６０から取得する（図７のステップＳ５７）。この際、加工部６０が作成した第２加工データが、格納部４０に提供される（図７のステップＳ８２）。そして、当該第２加工データが、格納部４０の記憶部４２に保存される。 When the processing unit 60 creates the second processed data, the storage unit 40 acquires the created second processed data from the processing unit 60 (step S57 in FIG. 7). At this time, the second processed data created by the processing unit 60 is provided to the storage unit 40 (step S82 in FIG. 7). Then, the second processed data is stored in the storage section 42 of the storage section 40 .
　次に、格納部４０が、第２加工データを第２端末５０に提供する（図７のステップＳ５８）。この際、格納部４０の処理部４３が、第２加工データを第２端末５０に送信する。このようにして、第２端末５０が、格納部４０から第２加工データを取得する（図７のステップＳ７４）。 Next, the storage unit 40 provides the second processed data to the second terminal 50 (step S58 in FIG. 7). At this time, the processing unit 43 of the storage unit 40 transmits the second processed data to the second terminal 50 . Thus, the second terminal 50 acquires the second processed data from the storage unit 40 (step S74 in FIG. 7).
　次いで、格納部４０が、第２加工データの評価結果を第２端末５０から取得する（図７のステップＳ５９）。この際、まず、第２端末５０を操作するユーザーが、シミュレーションデータを評価した場合と同様に、第２端末５０に提供された第２加工データを閲覧するとともに、当該第２加工データを評価する。そして、第２加工データを閲覧したユーザーが、第２端末５０の操作部５５を操作することにより、第２加工データの評価結果を入力する（図７のステップＳ７５）。そして、格納部４０が、第２端末５０から評価結果を取得する（図７のステップＳ５９）。 Next, the storage unit 40 acquires the evaluation result of the second processed data from the second terminal 50 (step S59 in FIG. 7). At this time, first, the user operating the second terminal 50 browses the second processed data provided to the second terminal 50 and evaluates the second processed data in the same manner as when evaluating the simulation data. . Then, the user who browsed the second processed data inputs the evaluation result of the second processed data by operating the operation unit 55 of the second terminal 50 (step S75 in FIG. 7). Then, the storage unit 40 acquires the evaluation result from the second terminal 50 (step S59 in FIG. 7).

　その後、第２端末５０を操作するユーザーの判定が、第２加工データの絵柄が満足のいく絵柄であるといった判定になるまで、上述した図７のステップＳ６５、Ｓ８１、Ｓ８２、Ｓ５７、Ｓ５８、Ｓ７４、Ｓ７５、Ｓ５９、Ｓ６０、Ｓ６４に示す工程が繰り返される。 Thereafter, steps S65, S81, S82, S57, S58, and S74 in FIG. , S75, S59, S60 and S64 are repeated.
　そして、加飾成形品１を作製する際に使用する加飾シート３が最終決定される。 Then, the decorative sheet 3 to be used when producing the decorative molded product 1 is finally determined.
　ところで、使用する加飾シート３が最終決定された場合、例えば、グラビア印刷によって、加飾シート３が量産される。この際、グラビア印刷に使用するシリンダーを作製する必要がある。一方、加飾シート３を量産した後に、加飾シート３の意匠が意図した意匠とは異なっていたことが判明する場合もある。このため、使用する加飾シート３が最終決定された場合であっても、加飾シート３を量産する前に、当該加飾シート３のサンプルを作製することが好ましい。この場合、加飾シート３のサンプルおよび加飾シート３は、以下のようにして製造することができる。 By the way, when the decorative sheet 3 to be used is finally decided, the decorative sheet 3 is mass-produced, for example, by gravure printing. At this time, it is necessary to produce a cylinder to be used for gravure printing. On the other hand, it may be found that the design of the decorative sheet 3 is different from the intended design after the decorative sheet 3 is mass-produced. Therefore, even when the decorative sheet 3 to be used is finally decided, it is preferable to prepare a sample of the decorative sheet 3 before mass-producing the decorative sheet 3 . In this case, the sample of the decorative sheet 3 and the decorative sheet 3 can be manufactured as follows.
　加飾シートのサンプルおよび加飾シートの製造方法
　まず、図６および図７に示す画像評価方法によって、画像データを評価する（図８のステップＳ９１）。 Decoration Sheet Sample and Decoration Sheet Manufacturing Method First, image data is evaluated by the image evaluation method shown in FIGS. 6 and 7 (step S91 in FIG. 8).
　次に、評価された画像データから、サンプル用印刷データを作成する（図８のステップＳ９２）。すなわち、最終決定された加飾シート３の画像データをサンプル用印刷データとする。 Next, sample print data is created from the evaluated image data (step S92 in FIG. 8). That is, the finally determined image data of the decorative sheet 3 is used as sample print data.
　次いで、サンプル用印刷データに基づいて、加飾シート３のサンプルを作製する（図８のステップＳ９３）。このようにして、加飾シート３のサンプルを得ることができる。なお、評価された画像データが、加飾シート３の絵柄だけでなく表面の凹凸に関する情報をもつ三次元データである場合、当該三次元データに基づいて加飾シート３の表面に凹凸構造を付与してもよい。例えば、３次元プリンタや２．５次元プリンタを用いて加飾シート３の表面に凹凸構造を再現することができる。 Next, a sample of the decorative sheet 3 is produced based on the sample print data (step S93 in FIG. 8). Thus, a sample of the decorative sheet 3 can be obtained. If the evaluated image data is three-dimensional data containing not only the pattern of the decorative sheet 3 but also information about the unevenness of the surface, an uneven structure is given to the surface of the decorative sheet 3 based on the three-dimensional data. You may For example, the uneven structure can be reproduced on the surface of the decorative sheet 3 using a three-dimensional printer or a 2.5-dimensional printer.
　ここで、加飾シート３のサンプルの絵柄は、インクジェット方式または熱溶融型熱転写方式による印刷法により印刷されてもよい。なかでも、加飾シート３のサンプルの絵柄は、溶融型熱転写方式によって印刷されることが好ましい。上述したように、加飾シート３は、例えばグラビア印刷によって量産される。ここで、加飾シート３のサンプルの絵柄をインクジェット方式によって印刷する場合、ノズルの目詰まりを防止するために、グラビア印刷によって加飾シート３を量産する場合に使用するインキと同一のインキを用いることができない可能性がある。一方、加飾シート３のサンプルの絵柄を溶融型熱転写方式によって印刷する場合、グラビア印刷によって加飾シート３を量産する場合に使用するインキと同一のインキを用いることができる。また、加飾シート３のサンプルの絵柄を溶融型熱転写方式によって印刷する場合、シリンダーを作製することなく、加飾シート３のサンプルを作製することもできる。このため、加飾シート３のサンプルの意匠を、量産される加飾シート３の意匠に限りなく近づけることができるとともに、サンプルの製造コストを低減できる。 Here, the pattern of the sample of the decorative sheet 3 may be printed by a printing method using an inkjet method or a hot-melt thermal transfer method. Above all, it is preferable that the design of the sample of the decorative sheet 3 is printed by a fusion-type thermal transfer method. As described above, the decorative sheet 3 is mass-produced, for example, by gravure printing. Here, when the pattern of the sample of the decorative sheet 3 is printed by the inkjet method, the same ink as that used when mass-producing the decorative sheet 3 by gravure printing is used in order to prevent clogging of the nozzles. may not be possible. On the other hand, when the design of the sample of the decorative sheet 3 is printed by the melt-type thermal transfer method, the same ink as that used when mass-producing the decorative sheet 3 by gravure printing can be used. Moreover, when printing a pattern of a sample of the decorative sheet 3 by a fusion-type thermal transfer method, the sample of the decorative sheet 3 can be produced without producing a cylinder. For this reason, the design of the sample of the decorative sheet 3 can be made infinitely close to the design of the mass-produced decorative sheet 3, and the manufacturing cost of the sample can be reduced.
　次に、作製されたサンプルを評価する（図８のステップＳ９４）。この際、例えば、加飾シート３を提供される側のユーザーが、サンプルを実際に視認することにより、サンプルの絵柄を評価してもよい。なお、加飾シート３を提供される側のユーザーは、第２端末５０に表示されたサンプルの絵柄を評価してもよい。サンプルの絵柄が満足のいく絵柄でない場合、最終決定された加飾シート３の画像データを更に加工することにより、サンプル用印刷データを修正することができる。このように、サンプルを作製した時点でサンプル用印刷データを修正することにより、グラビア印刷用のシリンダーを作製することなく、印刷用のデータに修正を加えることができる。このため、サンプルを作製した時点でサンプル用印刷データを修正することにより、加飾シート３を量産した後に印刷用のデータに修正を加える場合と比較して、加飾シート３の製造コストを低減できる。 Next, the manufactured sample is evaluated (step S94 in FIG. 8). At this time, for example, the user who is provided with the decorative sheet 3 may evaluate the design of the sample by actually visually recognizing the sample. The user who receives the decorative sheet 3 may evaluate the sample pattern displayed on the second terminal 50 . If the sample pattern is not satisfactory, the sample print data can be corrected by further processing the finally determined image data of the decorative sheet 3 . In this way, by correcting the sample print data at the time the sample is produced, the print data can be corrected without producing a gravure cylinder. Therefore, by correcting the print data for the sample when the sample is produced, the manufacturing cost of the decorative sheet 3 can be reduced compared to the case where the printing data is corrected after the decorative sheet 3 is mass-produced. can.
　一方、サンプルの絵柄が満足のいく絵柄であった場合、評価されたサンプルのサンプル用印刷データから、加飾シート用印刷データを作成する（図８のステップＳ９５）。すなわち、サンプル用印刷データを加飾シート用印刷データとする。 On the other hand, if the pattern of the sample is satisfactory, print data for the decorative sheet is created from the sample print data of the evaluated sample (step S95 in FIG. 8). That is, the sample print data is used as the decorative sheet print data.
　サンプルを評価する工程では、実際にサンプルを用いて評価用の加飾成形品を作製してもよい。評価用の加飾成形品は、射出成形装置や３Ｄプリンタを用いて成形部２を作成し、当該成形部２の表面にサンプルを適用することによって作製できる。サンプルは、例えば、成形部２の表面に貼り付けられてもよい。評価用の加飾成形品を用いることで、サンプルの意匠を三次元形状に適用された状態として確認することができる。３Ｄプリンタを用いて成形部２を作製することにより、より簡便にサンプルの評価を行うことができる。さらに、加飾シート３の意匠決定時の三次元ＣＡＤデータと、加飾シート３のサンプルを用いて加飾成形品を成形する際の三次元ＣＡＤデータが異なっていてもよい。具体的には、加飾シート３の意匠決定時の三次元ＣＡＤデータが、仮の三次元ＣＡＤデータであって、試作品の形状を表す三次元ＣＡＤデータであってもよい。一方、加飾シート３のサンプルを用いて加飾成形品を成形する際の三次元ＣＡＤデータが、修正後の三次元ＣＡＤデータであって、量産品の形状を表す三次元ＣＡＤデータであってもよい。これにより、加飾シート３の意匠開発と、加飾成形品１の意匠開発とが並行して進行する場合、加飾成形品１の意匠開発の期間を短縮できる。 In the process of evaluating the sample, the sample may actually be used to produce a decorative molded product for evaluation. A decorative molded product for evaluation can be produced by using an injection molding device or a 3D printer to create a molded part 2 and applying a sample to the surface of the molded part 2 . The sample may be attached to the surface of the molding portion 2, for example. By using the decorative molded product for evaluation, the design of the sample can be confirmed as being applied to a three-dimensional shape. By producing the molding part 2 using a 3D printer, the sample can be evaluated more easily. Furthermore, the three-dimensional CAD data when determining the design of the decorative sheet 3 and the three-dimensional CAD data when molding the decorative molded product using the sample of the decorative sheet 3 may be different. Specifically, the three-dimensional CAD data at the time of determining the design of the decorative sheet 3 may be provisional three-dimensional CAD data, and may be three-dimensional CAD data representing the shape of the prototype. On the other hand, the three-dimensional CAD data for molding the decorative molded product using the sample of the decorative sheet 3 is the corrected three-dimensional CAD data and the three-dimensional CAD data representing the shape of the mass-produced product. good too. As a result, when the design development of the decorative sheet 3 and the design development of the decorative molded product 1 proceed in parallel, the design development period of the decorative molded product 1 can be shortened.
　次に、加飾シート用印刷データに基づいて、加飾シート３を作製する（図８のステップＳ９６）。この際、例えば、まず、加飾シート用印刷データに基づいて、グラビア印刷用のシリンダーを作製する。そして、当該シリンダーを用いて、加飾シート３を量産する。なお、例えば、加飾シート３の生産数が少ない場合等には、グラビア印刷用のシリンダーを作製することなく、サンプルの絵柄を印刷した場合と同様に、溶融型熱転写方式によって加飾シート３の絵柄を印刷してもよい。この場合、加飾シート３の製造コストを更に低減できる。 Next, the decorative sheet 3 is produced based on the printing data for the decorative sheet (step S96 in FIG. 8). At this time, for example, first, a cylinder for gravure printing is produced based on the printing data for the decorative sheet. Then, using the cylinder, the decorative sheet 3 is mass-produced. In addition, for example, when the number of production of the decorative sheet 3 is small, the decorative sheet 3 is printed by a fusion type thermal transfer method in the same manner as in the case of printing a sample pattern without preparing a cylinder for gravure printing. You can print the pattern. In this case, the manufacturing cost of the decorative sheet 3 can be further reduced.
　ここで、加飾シート３の絵柄は、メタリック顔料又はパール顔料を含むインキを用いて印刷されても良い。例えば、加飾シート３の絵柄は、サンプルを作製した際に使用したインキを用いて印刷されることが好ましい。これにより、加飾シート３の意匠を、サンプルの意匠に限りなく近づけることができる。このため、加飾シート３の意匠が、意図した意匠から異なってしまうことを抑制できる。なお、評価された画像データが、加飾シート３の絵柄だけでなく表面の凹凸構造に関する情報をもつ三次元データである場合、当該三次元データに基づいて加飾シート３の表面に凹凸構造を付与してもよい。例えば、３次元プリンタや２．５次元プリンタを用いて加飾シート３の表面に凹凸構造を再現することができる。 Here, the pattern of the decorative sheet 3 may be printed using ink containing metallic pigments or pearl pigments. For example, the pattern of the decorative sheet 3 is preferably printed using the ink used when the sample was produced. Thereby, the design of the decorative sheet 3 can be made infinitely close to the design of the sample. Therefore, it is possible to prevent the design of the decorative sheet 3 from being different from the intended design. If the evaluated image data is three-dimensional data containing not only the pattern of the decorative sheet 3 but also information about the uneven structure of the surface, the uneven structure is formed on the surface of the decorative sheet 3 based on the three-dimensional data. may be given. For example, the uneven structure can be reproduced on the surface of the decorative sheet 3 using a three-dimensional printer or a 2.5-dimensional printer.

A sample of the decorative sheet 3 may be produced by a printing method using an inkjet method or a hot-melt thermal transfer method. The advantage of making samples by printing methods using an inkjet method or a hot-melt thermal transfer method is that there is no limitation due to the cylinder conditions (cylinder circumference or width) as in gravure printing, for example, it is longer than the cylinder circumference in gravure printing. It is possible to produce a long sample.

＜第２の実施形態＞
　以下、図面を参照して本開示の第２の実施形態について説明する。 <Second embodiment>
A second embodiment of the present disclosure will be described below with reference to the drawings.
　第２の実施形態の加飾成形品の構成及び製造方法は、図１乃至図４を参照して説明した第１の実施形態の加飾成形品の構成及び製造方法と同様である。このため、第２の実施形態では、図１に示す加飾成形品と同様の部分には同一符号を付して、加飾成形品の構成及び製造方法についての詳細な説明は省略する。 The configuration and manufacturing method of the decorative molded product of the second embodiment are the same as the configuration and manufacturing method of the decorative molded product of the first embodiment described with reference to FIGS. Therefore, in the second embodiment, the same reference numerals are assigned to the same parts as those of the decorative molded product shown in FIG. 1, and detailed description of the configuration and manufacturing method of the decorative molded product will be omitted.
　ところで、加飾シートを成形すると、加飾成形品の表面形状や成形型の形状によっては、加飾シートの一部の領域が著しく伸長する。当該一部の領域の伸び率は、例えば５０％～２００％になる。この場合、当該一部の領域は、成形前と比較して１．５～３倍に伸長する。加飾シートの一部の領域がこのように大きな伸び率で伸長すると、加飾シートの絵柄が顕著に歪むことあり、この結果、意図した意匠とは異なる意匠が加飾成形品に付与される場合がある。例えば、図１に示すように、加飾成形品１が、第１の面１ａと、第１の面１ａに対する傾斜角度θが４５°以上である第２の面１ｂと、第１の面１ａ及び第２の面１ｂが接続する接続領域１ｃとを含み、第１の面１ａから第２の面１ｂに亘って加飾シート３が適用される場合、接続領域１ｃにおいて、加飾シート３は著しく伸長する傾向にある。このような接続領域１ｃは、例えば、加飾成形品１の角部や隅部に含まれる。このように加飾シート３が著しく伸長する領域を加飾成形品１が含む場合、伸長による加飾シート３の絵柄の変形を予測することは難しい。このような接続領域１ｃでは加飾シート３が複数の方向に伸長されることもあり、その場合、伸長による加飾シート３の絵柄の変形を予測することは、さらに困難になる。また、このような接続領域１ｃは、観察者の注意を引きやすく、当該領域１ｃの加飾シート３の絵柄が加飾成形品１全体の意匠に与える影響も大きい。なお、第１の面１ａに対する第２の面１ｂの傾斜角度は、５０°以上、５５°以上、又は、６０°以上であってもよい。傾斜角度θの上限に制限はないが、例えば、９０°未満であってよい。 By the way, when the decorative sheet is molded, a part of the decorative sheet is remarkably elongated depending on the surface shape of the decorative molded product and the shape of the molding die. The elongation rate of the partial area is, for example, 50% to 200%. In this case, the partial region is stretched 1.5 to 3 times as compared to before molding. When a part of the decorative sheet is elongated at such a large elongation rate, the pattern of the decorative sheet is significantly distorted, and as a result, a design different from the intended design is imparted to the decorative molded product. Sometimes. For example, as shown in FIG. 1, a decorative molded product 1 has a first surface 1a, a second surface 1b having an inclination angle θ of 45° or more with respect to the first surface 1a, and a first surface 1a. and a connection area 1c to which the second surface 1b connects, and when the decorative sheet 3 is applied from the first surface 1a to the second surface 1b, in the connection area 1c, the decorative sheet 3 is It tends to grow significantly. Such connection regions 1c are included, for example, in corners and corners of the decorative molded product 1. As shown in FIG. When the decorative molded product 1 includes a region where the decorative sheet 3 is remarkably elongated, it is difficult to predict the deformation of the design of the decorative sheet 3 due to the expansion. In such a connection area 1c, the decorative sheet 3 may be stretched in a plurality of directions, and in such a case, it becomes more difficult to predict the deformation of the pattern of the decorative sheet 3 due to the stretching. Moreover, such a connection area 1c tends to attract the attention of an observer, and the pattern of the decorative sheet 3 in the area 1c has a great influence on the design of the entire decorative molded product 1. As shown in FIG. The inclination angle of the second surface 1b with respect to the first surface 1a may be 50° or more, 55° or more, or 60° or more. Although there is no upper limit to the inclination angle θ, it may be less than 90°, for example.
　加飾シートの著しい伸長によって加飾シートの絵柄が歪む場合、加飾成形品の表面形状や成形型の形状を修正することにより、絵柄の歪みを抑制することも考えられる。これにより、加飾成形品に付与される意匠を意図した意匠に近づけることができる。しかしながら、満足のいく加飾成形品が作製されるまで成形型を何度も作製し直すことは、加飾成形品の完成にかかる時間及びコストの増大に繋がる。 If the pattern on the decorative sheet is distorted due to the significant elongation of the decorative sheet, it is possible to suppress the distortion of the pattern by modifying the surface shape of the decorative molded product and the shape of the mold. As a result, the design imparted to the decorative molded product can be brought closer to the intended design. However, repeatedly remaking the mold until a satisfactory decorated molded product is produced increases the time and cost required to complete the decorated molded product.
　また、成形による加飾シートの各部の伸びを予測するだけでは、加飾シートの絵柄の変形を予測することはできない。同じ成形型で成形された加飾シートであっても、加飾シートの絵柄によって、観察者によって把握される成形前の加飾シートに対する成形後の加飾シートの絵柄の変形の程度が異なるからである。 In addition, it is not possible to predict the deformation of the pattern of the decorative sheet just by predicting the elongation of each part of the decorative sheet due to molding. Even if the decorative sheet is molded with the same mold, the degree of deformation of the pattern of the decorative sheet after molding as perceived by an observer differs depending on the pattern of the decorative sheet before molding. is.
　例えば、成形前の加飾シートが網目模様のように規則的な二次元配列パターンで構成される絵柄を有する場合、成形によって加飾シートの一部の領域が著しく伸長すれば、観察者は成形前の加飾シートに対する成形後の加飾シートの絵柄の変形に容易に気づく傾向にある。一方で、成形前の加飾シートが木目模様のような一見しただけでは規則性を把握しづらい絵柄を有する場合、成形によって加飾シートの一部の領域が著しく伸長しても、観察者は成形前の加飾シートに対する成形後の加飾シートの絵柄の変形に気づきにくい傾向にある。 For example, when a decorative sheet before molding has a pattern composed of a regular two-dimensional arrangement pattern such as a mesh pattern, if a part of the decorative sheet is significantly stretched by molding, the observer will not be able to see the molding. There is a tendency to easily notice the deformation of the pattern of the decorative sheet after molding with respect to the preceding decorative sheet. On the other hand, if the decorative sheet before molding has a pattern such as a wood grain pattern that is difficult to grasp the regularity of, even if a part of the decorative sheet is significantly stretched by molding, the observer will not be able to see it. It tends to be difficult to notice the deformation of the pattern of the decorative sheet after molding with respect to the decorative sheet before molding.
　また、同じ成形型で成形された加飾シートであっても、加飾シートを成形する際の加飾シートの絵柄と成形型との位置関係によって、観察者によって把握される成形前の加飾シートに対する成形後の加飾シートの絵柄の変形の程度は異なり得る。例えば、加飾シートの絵柄が複数の線で構成される縞模様である場合について考える。この場合、縞模様を構成する線が加飾シートの著しく伸長している領域上を伸びていれば、観察者は成形前の加飾シートに対する成形後の加飾シートの絵柄の変形に容易に気づく傾向にある。一方で、縞模様を構成する線が加飾シートの著しく伸長している領域上を伸びていなければ、観察者は成形前の加飾シートに対する成形後の加飾シートの絵柄の変形に気づきにくい傾向にある。 In addition, even if the decorative sheet is formed by the same mold, the positional relationship between the design of the decorative sheet and the mold when molding the decorative sheet can be perceived by an observer before molding. The degree of deformation of the pattern of the decorative sheet after molding on the sheet may differ. For example, consider the case where the pattern of the decorative sheet is a striped pattern composed of a plurality of lines. In this case, if the lines forming the striped pattern extend over the significantly elongated region of the decorative sheet, an observer can easily see the deformation of the pattern of the decorative sheet after molding compared to that of the decorative sheet before molding. tend to notice. On the other hand, if the lines forming the striped pattern do not extend over the significantly elongated region of the decorative sheet, the observer is less likely to notice the deformation of the pattern of the decorative sheet after molding with respect to that of the decorative sheet before molding. There is a tendency.
　加飾シートの絵柄の変形を評価するために、一つの成形型に対して異なる絵柄の加飾シートを用いて何度も加飾成形品を試作したり、一つの成形型につき絵柄と成形型との位置関係を変更して何度も加飾成形品を試作することも考えられるが、このような方法は、加飾成形品の完成にかかる時間及びコストの増大に繋がる。 In order to evaluate the deformation of the pattern of the decorative sheet, we used decorative sheets with different patterns on one molding die to make many prototypes of decorative molded products. Although it is conceivable to make prototypes of the decorated molded product many times by changing the positional relationship with the , such a method leads to an increase in the time and cost required to complete the decorated molded product.
　第２の実施形態による加飾成形品の製造方法には、加飾成形品を作製する際の加飾シートの絵柄の変形を、成形型を作製したり加飾成形品を作製することなく評価可能とするための工夫が成されている。 In the manufacturing method of the decorative molded product according to the second embodiment, the deformation of the pattern of the decorative sheet when manufacturing the decorative molded product is evaluated without manufacturing a mold or manufacturing the decorative molded product. Efforts have been made to make it possible.
　図示された例では、加飾成形品１の製造方法は、図１０に示す評価装置１２０を用いることにより、加飾成形品１を作製する際の加飾シート３の絵柄の変形を、成形型１０を作製したり加飾成形品１を作製することなく評価可能である。図１０に示す評価装置１２０は、記憶部１２１と、成形型データ生成部１２２と、演算部１２３と、伸び表示画像データ生成部１２４と、第２画像データ生成部１２５と、第３画像データ生成部１２６と、表示部１２７とを備えている。 In the illustrated example, the method for manufacturing the decorative molded product 1 uses the evaluation device 120 shown in FIG. It is possible to evaluate without producing 10 or producing the decorative molded product 1. The evaluation device 120 shown in FIG. 10 includes a storage unit 121, a molding die data generation unit 122, a calculation unit 123, a stretching display image data generation unit 124, a second image data generation unit 125, and a third image data generation unit. A portion 126 and a display portion 127 are provided.
　記憶部１２１には、加飾成形品１の三次元形状を表す成形品データが格納されている。成形品データは、例えば、三次元ＣＡＤデータである。成形品データは、例えば、加飾成形品の設計用ＣＡＤデータ、加飾成形品の外観形状を表す模型や画像データに基づいて生成される。成形品データは、加飾シート３の絵柄の変形の評価を行う者が生成してもよいし、当該評価を行う者以外の者（例えば、加飾成形品１の作製を依頼する顧客）から取得してもよい。 The storage unit 121 stores molded product data representing the three-dimensional shape of the decorative molded product 1. The molded product data is, for example, three-dimensional CAD data. The molded article data is generated based on, for example, CAD data for designing the decorated molded article, a model representing the external shape of the decorated molded article, and image data. The molded product data may be generated by a person who evaluates the deformation of the pattern of the decorative sheet 3, or may be generated by a person other than the person who performs the evaluation (for example, a customer who requests the production of the decorative molded product 1). may be obtained.
　また、記憶部１２１には、成形型１０を用いて成形される前の加飾シート３を表す画像データ（以下では、「第１画像データ」とも称する。）が格納されている。第１画像データが表す加飾シート３は、絵柄を有している。第１画像データは、例えば、加飾シート３の見本に基づいて生成される。第１画像データは、加飾シート３の意匠を含む二次元の画像データであってもよいし、加飾シート３の意匠と表面の構造とを含む三次元の画像データであってもよい。第１画像データは、加飾シート３の絵柄の変形の評価を行う者が生成してもよいし、当該評価を行う者以外の者（例えば、加飾シート３のサプライヤー）から取得してもよい。 The storage unit 121 also stores image data representing the decorative sheet 3 before being molded using the molding die 10 (hereinafter also referred to as "first image data"). The decorative sheet 3 represented by the first image data has a pattern. The first image data is generated based on a sample of the decorative sheet 3, for example. The first image data may be two-dimensional image data including the design of the decorative sheet 3 or three-dimensional image data including the design and surface structure of the decorative sheet 3 . The first image data may be generated by a person who evaluates the deformation of the pattern of the decorative sheet 3, or may be obtained from a person other than the person who evaluates (for example, the supplier of the decorative sheet 3). good.
　成形型データ生成部１２２は、記憶部１２１に格納された成形品データに基づいて、加飾シート３の成形に用いられる成形型１０として仮決定された成形型の三次元形状を表す成形型データを生成する。例えば、成形品データが図１１に示すような三次元形状を表す場合、当該成形品データに基づいて図１２に示す成形型データが生成される。図１２に示す例では、成形型データは、加飾成形品に対応する領域（後述する「第１領域１３１」に対応する領域）に関するデータと、その他の領域（後述する「第２領域１３２」に対応する領域）に関するデータとを含んでいる。成形型データが加飾成形品に対応する領域以外の領域に関するデータを含むことにより、当該成形型データが表す成形型で成形した場合における加飾シート３の各部の伸びを、より精度良く評価することができる。成形型データは、例えば、三次元ＣＡＤデータである。なお、成形型１０の仮決定には、例えば、上述した加飾成形品１の作製方法等が考慮されてもよい。言い換えると、加飾成形品１の作製方法として上述した第１の製造方法及び第２の製造方法の一方が用いられる場合と他方が用いられる場合とで、異なる成形型が、加飾シート３の成形に用いられる成形型１０として仮決定されてよい。また、第１の製造方法、第２の製造方法及びその他の製造方法のうち一つの方法が用いられる場合と別の方法が用いられる場合とで、異なる成形型が、加飾シート３の成形に用いられる成形型１０として仮決定されてもよい。 Mold data generation unit 122 generates mold data representing the three-dimensional shape of a mold temporarily determined as mold 10 to be used for molding decorative sheet 3 based on molded product data stored in storage unit 121. to generate For example, when molded product data represents a three-dimensional shape as shown in FIG. 11, mold data shown in FIG. 12 is generated based on the molded product data. In the example shown in FIG. 12, the molding die data includes data relating to the area corresponding to the decorative molded product (area corresponding to the "first area 131" described later) and other areas ("second area 132" described later). and data on the area corresponding to the Since the mold data includes data related to areas other than the area corresponding to the decorative molded product, the elongation of each part of the decorative sheet 3 when molded with the mold represented by the mold data can be evaluated more accurately. be able to. Mold data is, for example, three-dimensional CAD data. It should be noted that the provisional determination of the mold 10 may take into account, for example, the method of manufacturing the above-described decorative molded product 1 . In other words, depending on whether one of the above-described first manufacturing method and second manufacturing method is used as the method for manufacturing the decorative molded product 1 and the other method, different molds are used to manufacture the decorative sheet 3. It may be tentatively determined as the mold 10 used for molding. In addition, different molds are used for molding the decorative sheet 3 depending on whether one of the first manufacturing method, the second manufacturing method, and other manufacturing methods is used and when another method is used. The mold 10 to be used may be tentatively determined.
　演算部１２３は、加飾シート３を仮決定された成形型１０で成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを、成形型データに基づいて算出する。 The calculation unit 123 calculates the elongation of each part of the decorative sheet 3 after molding with respect to the decorative sheet 3 before molding when molding the decorative sheet 3 with the molding die 10 that has been temporarily determined, based on the molding die data. calculate.
　伸び表示画像データ生成部１２４は、仮決定された成形型１０で成形後の加飾シート３の各部と算出した加飾シート３の各部の伸びとの対応関係を視覚的に示す画像データ（以下、「伸び表示画像データ」とも称する。）を生成する。図１３及び図１４は伸び表示画像データの例であり、図１２に示す成形型データに基づいて算出した加飾シート３の各部の伸びを示している。図１３に示す伸び表示画像データは、算出した加飾シート３の各部の伸びを、当該伸びの大きさに応じた色で示している。図１３に示す例では、伸び表示画像データは、伸びの大きさと色の対応関係を示すチャート１３０を含んでいる。図１３に示すチャート１３０では、加飾シート３の伸びがない状態（伸び率が０％の状態）を「１」と設定しており、例えば伸びがない状態から２０％伸びた状態（伸び率が２０％の状態）を「１．２」と設定しているが、あくまで例示であり、伸びの大きさの表現方法はこの表現方法に限定されるものではない。また、図１４に示す伸び表示画像データは、算出した加飾シート３の各部の伸びを、当該伸びの大きさに応じた線の歪みで示している。図１４に示す伸び表示画像データは、方眼を形成する線の歪みにより、算出した加飾シート３の各部の伸びを表現しているが、これに限定されない。このような伸び表示画像データにより、成形後の加飾シート３の各部と算出した加飾シート３の各部の伸びとの対応関係を、容易に把握することができる。 The elongation display image data generation unit 124 generates image data (hereinafter referred to as , also referred to as “stretched display image data”). 13 and 14 are examples of stretch display image data, showing the stretch of each part of the decorative sheet 3 calculated based on the mold data shown in FIG. The elongation display image data shown in FIG. 13 indicates the calculated elongation of each part of the decorative sheet 3 in a color corresponding to the magnitude of the elongation. In the example shown in FIG. 13, the stretch display image data includes a chart 130 showing the correspondence between the magnitude of stretch and the color. In the chart 130 shown in FIG. 13, the state in which the decorative sheet 3 is not stretched (elongation rate is 0%) is set to "1". is 20%) is set to "1.2", but this is merely an example, and the expression method of the magnitude of elongation is not limited to this expression method. The stretch display image data shown in FIG. 14 indicates the calculated stretch of each part of the decorative sheet 3 by distorting the line according to the magnitude of the stretch. The elongation display image data shown in FIG. 14 expresses the calculated elongation of each part of the decorative sheet 3 by the distortion of the lines forming the grid, but is not limited to this. From such elongation display image data, it is possible to easily grasp the correspondence relationship between each part of the decorative sheet 3 after molding and the calculated elongation of each part of the decorative sheet 3 .
　第２画像データ生成部１２５は、仮決定された成形型１０で成形後の加飾シート３を表す画像データ（以下、「第２画像データ」とも称する。）を生成する。第２画像データは、演算部１２３で算出した加飾シート３の各部の伸びと、記憶部１２１に格納された第１画像データとに基づいて生成される。このような第２画像データにより、仮決定された成形型１０で成形した加飾シート３の絵柄の変形を容易に把握することができ、変形後の絵柄によって表される意匠を容易に把握することができる。 The second image data generation unit 125 generates image data (hereinafter also referred to as "second image data") representing the decorative sheet 3 after molding with the tentatively determined molding die 10. The second image data is generated based on the elongation of each portion of the decorative sheet 3 calculated by the calculation unit 123 and the first image data stored in the storage unit 121 . With such second image data, the deformation of the pattern of the decorative sheet 3 formed by the temporarily determined forming die 10 can be easily grasped, and the design represented by the pattern after deformation can be easily grasped. be able to.
　具体的には、第２画像データ生成部１２５は、第１画像データが表す成形前の加飾シート３の絵柄を、演算部１２３で算出した加飾シート３の各部の伸びに応じて変形させることにより、第２画像データを生成する。また、第１画像データが表す加飾シート３が着色されている場合、第２画像データ生成部１２５は、第１画像データが示す成形前の加飾シート３の各部の色を、演算部１２３で算出した加飾シート３の各部の伸びに応じた色に変更することにより（例えば、加飾シート３のうち伸びの大きい領域の色を、第１画像データが表す加飾シート３の色よりも淡い色に変更することにより）、第２画像データを生成してもよい。 Specifically, the second image data generation unit 125 deforms the pattern of the decorative sheet 3 before molding represented by the first image data according to the elongation of each part of the decorative sheet 3 calculated by the calculation unit 123. Thereby, the second image data is generated. Further, when the decorative sheet 3 represented by the first image data is colored, the second image data generation unit 125 calculates the color of each part of the unmolded decorative sheet 3 represented by the first image data. (for example, the color of the area of the decorative sheet 3 with large stretch is changed from the color of the decorative sheet 3 represented by the first image data by changing the color to a lighter color) to generate the second image data.
　例えば、第１画像データが図１５に示すような縞模様の絵柄を有する加飾シートを表す場合であって、演算部１２３で算出された加飾シート３の各部の伸びが図１３又は図１４に示す伸び表示画像データで表される場合について考える。この場合、第２画像データ生成部１２５で生成される第２画像データによって表される成形後の加飾シート３は、概ね図１６に示すような加飾シートである。図１６に示す加飾シート３の縞模様は、加飾シート３のうち演算部１２３で算出された伸びが大きい領域で、大きく歪んでいる。なお、図１６に示す加飾シート３は、加飾成形品１の一部として用いられる第１領域１３１と、第１領域１３１以外の領域である第２領域１３２とを含んでいる。 For example, when the first image data represents a decorative sheet having a striped pattern as shown in FIG. Consider the case represented by the stretched display image data shown in . In this case, the molded decorative sheet 3 represented by the second image data generated by the second image data generation unit 125 is generally a decorative sheet as shown in FIG. The striped pattern of the decorative sheet 3 shown in FIG. 16 is greatly distorted in the region of the decorative sheet 3 where the elongation calculated by the calculation unit 123 is large. The decorative sheet 3 shown in FIG. 16 includes a first region 131 used as part of the decorative molded product 1 and a second region 132 other than the first region 131 .
　第３画像データ生成部１２６は、第２画像データに基づいて、上記第１領域１３１のみを表す第３画像データを生成する。すなわち、第３画像データは、第２画像データが表す成形後の加飾シート３から加飾成形品１に不要な領域である第２領域１３２をトリミングした加飾シート３を表す。例えば、第２画像データが表す加飾シートが図１６に示す加飾シート３である場合、第３画像データが表す加飾シートは、図１７に示す加飾シート３である。このような第３画像データにより、加飾シート３によって加飾成形品１に付与される意匠を、容易に把握することができる。なお、本明細書において「第１領域のみを表す」という表現は、主として第１領域１３１を表すことを意味し、第１領域１３１と共に第２領域１３２の一部を表していてもよいことを意味する。 The third image data generator 126 generates third image data representing only the first region 131 based on the second image data. That is, the third image data represents the decorative sheet 3 obtained by trimming the second region 132, which is an unnecessary region for the decorative molded product 1, from the molded decorative sheet 3 represented by the second image data. For example, when the decorative sheet represented by the second image data is the decorative sheet 3 shown in FIG. 16, the decorative sheet represented by the third image data is the decorative sheet 3 shown in FIG. With such third image data, the design imparted to the decorative molded product 1 by the decorative sheet 3 can be easily grasped. In this specification, the expression “representing only the first region” means mainly representing the first region 131, and may represent part of the second region 132 together with the first region 131. means.
　表示部１２７は、伸び表示画像データ生成部１２４からの入力を受けて、伸び表示画像データを表示する。また、図示された例では、表示部１２７は、第３画像データ生成部１２６からの入力を受けて、第３画像データを表示する。表示部１２７は、第２画像データ生成部１２５からの入力を受けて第２画像データを表示するものであってもよい。 The display unit 127 receives the input from the stretch display image data generation unit 124 and displays the stretch display image data. Also, in the illustrated example, the display unit 127 receives an input from the third image data generation unit 126 and displays the third image data. The display unit 127 may receive the input from the second image data generation unit 125 and display the second image data.
　なお、図１１及び図１２において、成形品データや成形型データは、加飾成形品１や成形型１０の平面視における三次元形状を表しているが、これに限られない。成形品データや成形型データは、加飾成形品１や成形型１０を任意の方向から見た場合（例えば、側方、斜め上方又は斜め下方から見た場合）における三次元形状を表してもよい。同様に、図１３、図１４、図１６及び図１７において、伸び表示画像データ、第２画像データ及び第３画像データは、成形後の加飾シート３の平面視における三次元形状を表しているが、これに限られない。 In addition, in FIGS. 11 and 12, the molded product data and the mold data represent the three-dimensional shapes of the decorative molded product 1 and the mold 10 in plan view, but are not limited to this. The molded product data and mold data may represent the three-dimensional shape when the decorative molded product 1 and mold 10 are viewed from an arbitrary direction (for example, when viewed from the side, obliquely upward, or obliquely downward). good. Similarly, in FIGS. 13, 14, 16 and 17, the stretch display image data, the second image data and the third image data represent the three-dimensional shape of the decorative sheet 3 after molding in plan view. However, it is not limited to this.
　例えば、伸び表示画像データ、第２画像データ及び第３画像データは、成形後の加飾シート３を任意の方向から見た場合（例えば、側方、斜め上方又は斜め下方から見た場合）における三次元形状を表してもよい。とりわけ、第２画像データや第３画像データが側方、斜め上方又は斜め下方から見た成形後の加飾シート３を表すことにより、上述した接続領域１ｃにおける加飾シート３の絵柄の状態を、より容易に把握することができる。また、第２画像データや第３画像データが斜め上方又は斜め下方から見た成形後の加飾シート３を表すことにより、表示部１２７に、成形品１の複数の面（上面又は下面及び側面）並びにこれらの面が接続する角部又は隅部（例えば、図１に示す第１の面１ａ及び第２の面１ｂ並びに接続領域１ｃ）を同時に表示することができる。この結果、後述する加飾シート３の全体評価を行う者は、上記複数の面及び上記角部又は隅部における加飾シート３の絵柄の状態を、同時に把握することができる。例えば、後述する図１９～図２１Ｂに示す例では、第２画像データや第３画像データは、斜め上方から見た成形後の加飾シート３を表している。このような第２画像データや第３画像データにより、表示部１２７には、加飾成形品１の上面及び側面並びにこれらの面が接続する角部又は隅部が同時に表示される。この結果、上記全体評価を行う者は、加飾成形品１の上面及び側面並びにこれらの面が接続する角部又は隅部における加飾シート３の絵柄の状態を、同時に確認することができる。 For example, the stretched display image data, the second image data, and the third image data are when the decorative sheet 3 after molding is viewed from an arbitrary direction (for example, when viewed from the side, obliquely upward, or obliquely downward). It may represent a three-dimensional shape. In particular, the second image data and the third image data represent the decorative sheet 3 after molding as viewed from the side, obliquely upward, or obliquely downward, so that the state of the pattern of the decorative sheet 3 in the connection region 1c described above can be expressed. , can be grasped more easily. Further, the second image data and the third image data represent the molded decorative sheet 3 viewed obliquely from above or from obliquely below, so that the display unit 127 displays a plurality of surfaces (upper surface or lower surface and side surfaces) of the molded product 1. ) and the corners or corners where these faces connect (eg, the first face 1a and the second face 1b and the connection area 1c shown in FIG. 1) can be displayed simultaneously. As a result, a person who performs an overall evaluation of the decorative sheet 3, which will be described later, can simultaneously grasp the states of the patterns of the decorative sheet 3 on the plurality of surfaces and the corners. For example, in the examples shown in FIGS. 19 to 21B, which will be described later, the second image data and the third image data represent the decorative sheet 3 after molding as viewed obliquely from above. With such second image data and third image data, the display unit 127 simultaneously displays the upper surface and side surfaces of the decorative molded product 1 and the corners or corners where these surfaces are connected. As a result, the person who performs the overall evaluation can simultaneously check the top and side surfaces of the decorative molded product 1 and the pattern of the decorative sheet 3 at the corners where these surfaces are connected.
　また、表示部１２７では、上記全体評価を行う者の要求に応じて（例えば、キーボードやマウス等の入力手段（図示せず）が操作されることによって）、伸び表示画像データ、第２画像データ及び第３画像データが表す加飾シート３を、並進、回転、拡大及び／縮小して表示可能であってもよい。これにより、加飾成形品１を実際に手に取って観察する場合と同様に、加飾シート３を観察することができる。 In addition, in the display unit 127, according to the request of the person who conducts the overall evaluation (for example, by operating input means (not shown) such as a keyboard or a mouse), the expanded display image data and the second image data are displayed. and the decorative sheet 3 represented by the third image data can be displayed in translation, rotation, enlargement and/or reduction. Accordingly, the decorative sheet 3 can be observed in the same manner as when the decorative molded article 1 is actually picked up and observed.
　次に、図１８を参照して、図１０に示す評価装置１２０を用いた加飾シート３の絵柄の変形の評価方法及び加飾成形品１の製造方法について説明する。 Next, referring to FIG. 18, a method for evaluating deformation of the pattern of the decorative sheet 3 and a method for manufacturing the decorative molded product 1 using the evaluation device 120 shown in FIG. 10 will be described.
　まず、成形品データ及び第１画像データを生成又は取得し、記憶部１２１に格納する（ステップＳ２０１）。次に、成形品データに基づいて成形型１０を仮決定する（ステップＳ２０２）。次に、成形型データ生成部１２２において、仮決定された成形型１０の三次元形状を表す成形型データを生成する（ステップＳ２０３）。次に、演算部１２３において、成形型データに基づいて、仮決定された成形型１０で加飾シート３を成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを算出する（ステップＳ２０４）。次に、伸び表示画像データ生成部１２４において伸び表示画像データを生成し、表示部１２７に表示する（ステップＳ２０５）。表示部１２７に表示された伸び表示画像データに基づいて、成形後の加飾シート３の伸びを評価する（ステップＳ２０６）。仮決定された成形型１０で成形後の加飾シートの各部の伸びが予め決めた閾値以下である場合（ステップＳ２０６の「Ｙｅｓ」）、第２画像データ生成部１２５において第２画像データを生成する（ステップＳ２０７）。次に、第３画像データ生成部１２６において、第２画像データから第３画像データを生成し、表示部１２７に表示する（ステップＳ２０８）。そして、表示部１２７に表示された第３画像データに基づいて、加飾シート３の第１領域１３１の全体評価を行う。全体評価は、第１領域１３１の各部における加飾シート３の絵柄の変形の評価を含む。全体評価は、ステップＳ２０６で加飾シート３の伸びの評価を行った者以外の者（例えば、加飾成形品１の作製を依頼した顧客）が行ってもよい。第３画像データで表される加飾シート３が承認された場合（ステップＳ２０９の「Ｙｅｓ」）、ステップＳ２０２で仮決定した成形型１０を、加飾成形品１の作製に用いる成形型として（すなわち、加飾シート３の成形に用いられる成形型として）決定する。そして、決定された成形型１０を作製し、作製された成形型１０と第１画像データが表す加飾シート３とを用いて加飾成形品１を製造する。 First, molded product data and first image data are generated or acquired, and stored in the storage unit 121 (step S201). Next, the molding die 10 is tentatively determined based on the molded product data (step S202). Next, the molding die data generator 122 generates molding die data representing the three-dimensional shape of the temporarily determined molding die 10 (step S203). Next, in the calculation unit 123, each part of the decorated sheet 3 after molding with respect to the decorated sheet 3 before molding when molding the decorative sheet 3 with the molding die 10 temporarily determined based on the molding die data is calculated (step S204). Next, the expanded display image data is generated by the expanded display image data generation unit 124 and displayed on the display unit 127 (step S205). The elongation of the decorative sheet 3 after molding is evaluated based on the elongation display image data displayed on the display unit 127 (step S206). When the elongation of each part of the decorative sheet after molding by the tentatively determined molding die 10 is equal to or less than the predetermined threshold ("Yes" in step S206), the second image data generator 125 generates the second image data. (step S207). Next, the third image data generation unit 126 generates third image data from the second image data, and displays it on the display unit 127 (step S208). Then, based on the third image data displayed on the display unit 127, the overall evaluation of the first region 131 of the decorative sheet 3 is performed. The overall evaluation includes evaluation of deformation of the pattern of the decorative sheet 3 in each part of the first area 131 . The overall evaluation may be performed by a person other than the person who evaluated the elongation of the decorative sheet 3 in step S206 (for example, the customer who requested the production of the decorative molded product 1). If the decorative sheet 3 represented by the third image data is approved ("Yes" in step S209), the mold 10 tentatively determined in step S202 is used as the mold used to produce the decorative molded product 1 ( That is, it is determined as a mold used for molding the decorative sheet 3 . Then, the determined mold 10 is produced, and the decorated molded product 1 is produced using the produced mold 10 and the decorative sheet 3 represented by the first image data.
　ステップＳ２０６において成形後の加飾シート３のいずれかの部分の伸びが上記閾値よりも大きい場合（ステップＳ２０６の「Ｎｏ」）、及び、ステップＳ２０９において第３画像データが承認されない場合（ステップＳ２０９の「Ｎｏ」）、ステップＳ２０２に戻り、再び成形型の仮決定を行う。具体的には、ステップＳ２０６又はステップＳ２０９を実施する前にステップＳ２０２で仮決定された成形型を変更又は修正する。その後、変更又は修正された成形型に基づいて、ステップＳ２０３以降の処理を繰り返す。 If the elongation of any portion of the decorative sheet 3 after molding is greater than the threshold in step S206 (“No” in step S206), and if the third image data is not approved in step S209 ( "No"), the process returns to step S202, and the mold is tentatively determined again. Specifically, the mold tentatively determined in step S202 is changed or corrected before performing step S206 or step S209. After that, the processing after step S203 is repeated based on the changed or corrected mold.
　なお、上述してきた一実施形態に対して様々な変更を加えることが可能である。 It should be noted that various modifications can be made to the embodiment described above.
　例えば、図１８に示す例では、ステップＳ２０９において、第３画像データに基づいて加飾シート３の第１領域１３１の全体評価を行っているが、これに限られない。ステップＳ２０９では、上記全体評価を、第２画像データに基づいて行ってもよい。上記全体評価を第２画像データに基づいて行う場合、第３画像データを生成しなくてもよい。すなわち、図１８のステップＳ２０８の処理を行わなくてもよい。 For example, in the example shown in FIG. 18, in step S209, the overall evaluation of the first region 131 of the decorative sheet 3 is performed based on the third image data, but the present invention is not limited to this. In step S209, the overall evaluation may be performed based on the second image data. When performing the overall evaluation based on the second image data, the third image data need not be generated. That is, the process of step S208 in FIG. 18 may not be performed.
　また、図１８のステップＳ２０９において第３画像データが承認されない場合（ステップＳ２０９の「Ｎｏ」）、ステップＳ２０２に戻って成形型の仮決定を再度行う代わりに、第２画像データの生成に用いられる第１画像データを変更又は修正してもよい。この場合、変更又は修正後の第１画像データに基づいて第２画像データ及び第３画像データを生成し、ステップＳ２０９において承認が得られたら、変更又は修正後の第１画像データが表す加飾シート３を用いて加飾成形品１を製造すればよい。 Also, if the third image data is not approved in step S209 of FIG. 18 (“No” in step S209), instead of returning to step S202 and re-determining the mold, it is used to generate the second image data. The first image data may be changed or modified. In this case, the second image data and the third image data are generated based on the modified or modified first image data, and if approval is obtained in step S209, the decoration represented by the modified or modified first image data The decorative molded product 1 may be manufactured using the sheet 3 .
　具体的には、ステップＳ２０７で生成される第２画像データが、図１６に示す加飾シート３を表す場合について考える。この場合、加飾シート３の縞模様を形成する線の間隔を広げることにより、歪みの少ない縞模様を加飾成形品１に付与することができる。したがって、第１画像データが表す加飾シート３の縞模様の線の間隔が広がるように第１画像データを修正し、修正後の第１画像データを用いて第２画像データ及び第３画像データを生成する。あるいは、この場合、加飾シート３の縞模様と仮決定された成形型との位置関係を変更することにより、歪みの少ない縞模様を加飾成形品１に付与することができる。したがって、第１画像データが表す加飾シート３の縞模様を構成する複数の線が当該複数の線の並ぶ方向に沿って平行移動するように第１画像データを修正し、修正後の第１画像データを用いて第２画像データ及び第３画像データを生成する。そして、ステップＳ２０９において第３画像データが承認されたら、修正後の第１画像データが表す加飾シート３を用いて加飾成形品１を製造する。これにより、歪みの少ない縞模様が付与された加飾成形品１を製造することができる。 Specifically, consider the case where the second image data generated in step S207 represents the decorative sheet 3 shown in FIG. In this case, by increasing the distance between the lines forming the striped pattern of the decorative sheet 3, the striped pattern with less distortion can be imparted to the decorative molded product 1. Therefore, the first image data is corrected so that the intervals between the lines of the striped pattern of the decorative sheet 3 represented by the first image data are widened, and the corrected first image data is used to obtain the second image data and the third image data. to generate Alternatively, in this case, by changing the positional relationship between the striped pattern of the decorative sheet 3 and the temporarily determined mold, the striped pattern with less distortion can be imparted to the decorated molded product 1 . Therefore, the first image data is corrected so that the plurality of lines forming the striped pattern of the decorative sheet 3 represented by the first image data are translated along the direction in which the plurality of lines are arranged, and the corrected first image data The image data is used to generate second image data and third image data. Then, when the third image data is approved in step S209, the decorative molded product 1 is manufactured using the decorative sheet 3 represented by the corrected first image data. As a result, it is possible to manufacture the decorative molded product 1 having a striped pattern with little distortion.
　あるいは、第１画像データを、規則的な二次元配列パターンで構成される絵柄を有する加飾シートの画像データから、一見しただけでは規則性を把握しづらい絵柄を有する加飾シートの画像データに変更する場合について考える。具体例として、ステップＳ２０１で生成又は取得される第１画像データが表す加飾シートの絵柄が規則的な二次元配列パターンで構成される網目模様であり、ステップＳ２０５で生成される伸び表示画像データが図１９に示す画像データである場合であって、これらの画像データに基づいてステップＳ２０７で生成される第２画像データが図２０Ａに示す画像データである場合について考える。図２０Ｂに、図２０Ａの第２画像データの一部を拡大して示す。この場合、図１９の伸び表示画像データと図２０Ａ及び図２０Ｂの第２画像データとを比較することにより理解されるように、加飾シート３の伸びが大きな領域では、第２画像データから上記網目模様の歪みが容易に把握される。この第２画像データから生成された第３画像データがステップＳ２０９で承認されない場合、第１画像データを、例えば、一見しただけでは規則性を把握しづらい木目模様の絵柄を有する加飾シートの画像データに変更する。これにより、ステップＳ２０７において、変更後の第１画像データと図１９の伸び表示画像データとから、図２１Ａに示すような第２画像データが生成される。図２１Ｂに、図２１Ａの第２画像データの一部を拡大して示す。この場合、図１９の伸び表示画像データと図２１Ａ及び図２１Ｂの第２画像データとを比較することにより理解されるように、加飾シート３の伸びが大きな領域においても、第２画像データから上記木目模様の歪みは容易には把握されない。そして、ステップＳ２０９において第３画像データが承認されたら、変更後の第１画像データが表す加飾シート３を用いて加飾成形品１を製造する。これにより、歪みが把握されにくい木目模様が付与された加飾成形品１を製造することができる。なお、ステップＳ２０９で複数の第３画像データ（あるいは複数の第２画像データ）を同時に比較することができるように、ステップＳ２０８（あるいはステップＳ２０７）で、表示部１２７に複数の第３画像データ（あるいは複数の第２画像データ）を表示してもよい。 Alternatively, the first image data is changed from the image data of the decorative sheet having a pattern composed of a regular two-dimensional array pattern to the image data of the decorative sheet having a pattern whose regularity is difficult to grasp at first glance. Think about when to change. As a specific example, the pattern of the decorative sheet represented by the first image data generated or acquired in step S201 is a mesh pattern formed of a regular two-dimensional array pattern, and the stretched display image data generated in step S205. is the image data shown in FIG. 19, and the second image data generated in step S207 based on these image data is the image data shown in FIG. 20A. FIG. 20B shows an enlarged portion of the second image data of FIG. 20A. In this case, as can be understood by comparing the stretch display image data of FIG. 19 with the second image data of FIGS. Distortion of the mesh pattern is easily grasped. If the third image data generated from the second image data is not approved in step S209, the first image data is replaced with, for example, an image of a decorative sheet having a wood grain pattern whose regularity is difficult to grasp at first glance. change to data. As a result, in step S207, second image data as shown in FIG. 21A is generated from the changed first image data and the expanded display image data of FIG. FIG. 21B shows an enlarged portion of the second image data of FIG. 21A. In this case, as understood by comparing the stretched display image data of FIG. 19 with the second image data of FIGS. 21A and 21B, even in the region where the decorative sheet 3 stretches greatly, The distortion of the wood grain pattern is not easily grasped. Then, when the third image data is approved in step S209, the decorated molded product 1 is manufactured using the decorated sheet 3 represented by the changed first image data. As a result, it is possible to manufacture the decorative molded product 1 provided with a wood grain pattern in which distortion is difficult to grasp. In addition, in step S208 (or step S207), a plurality of third image data (or a plurality of second image data) are displayed on the display unit 127 so that the plurality of third image data (or a plurality of second image data) can be simultaneously compared in step S209. Alternatively, a plurality of second image data) may be displayed.
　また、ある加飾シート３の伸び率が加飾成形品１の成形方法（例えば、上述した第１の製造方法、第２の製造方法及び第３の製造方法）によって異なる場合には、当該加飾シート３を表す第１画像データに基づいて生成される伸び表示画像データも、加飾成形品１の成形方法によって異なってよい。言い換えると、１つの加飾シート３と互いに異なる複数の成形方法とに基づいて、互いに異なる複数の伸び表示画像データが生成されてよい。この場合、ステップＳ２０６で加飾成形品１の成形方法の違いによる加飾シート３の伸びの違いを比較可能なよう、ステップＳ２０５で、互いに異なる複数の成形方法に基づいて生成された互いに異なる複数の伸び表示画像データを、表示部１２７に表示してもよい。例えば、上記第１の製造方法に基づいて生成された伸び表示画像データ、上記第２の製造方法に基づいて生成された伸び表示画像データ、及び上記第３の製造方法に基づいて生成された伸び表示画像データのうち、２以上の伸び表示画像データを、表示部１２７に表示してもよい。 In addition, when the elongation rate of a certain decorative sheet 3 differs depending on the molding method of the decorative molded product 1 (for example, the first manufacturing method, the second manufacturing method, and the third manufacturing method described above), the The stretched display image data generated based on the first image data representing the decorative sheet 3 may also differ depending on the molding method of the decorative molded product 1 . In other words, a plurality of different stretched display image data may be generated based on one decorative sheet 3 and a plurality of different forming methods. In this case, in step S205, a plurality of different elongations generated based on a plurality of different molding methods are performed so that the difference in elongation of the decorative sheet 3 due to the difference in the molding method of the decorative molded product 1 can be compared in step S206. may be displayed on the display unit 127 . For example, elongation display image data generated based on the first manufacturing method, elongation display image data generated based on the second manufacturing method, and elongation generated based on the third manufacturing method Of the display image data, two or more expanded display image data may be displayed on the display unit 127 .
　このように、図１８に示す例では、ステップＳ２０２において成形型データ生成部１２２が１つの第１画像データに基づいて１つの成形型データを生成し、ステップＳ２０７において第２画像データ生成部１２５が１つの成形型データ及び１つの第１画像データに基づいて１つの第２画像データを生成する場合について説明したが、これに限られない。 Thus, in the example shown in FIG. 18, in step S202 the molding die data generation unit 122 generates one molding die data based on one piece of first image data, and in step S207 the second image data generation unit 125 Although a case has been described in which one piece of second image data is generated based on one piece of molding die data and one piece of first image data, the present invention is not limited to this.
　例えば、第２画像データ生成部１２５は、複数の第１画像データに基づいて、複数の第２画像データを生成してもよい。また、第３画像データ生成部１２６は、複数の第２画像データに基づいて、複数の第３画像データを生成してもよい。この場合、複数の第２画像データ及び／又は複数の第３画像データから一の第２画像データ及び／又は一の第３画像データを選択することにより、加飾成形品１の作製に用いる加飾シート３を決定してもよい。 For example, the second image data generator 125 may generate a plurality of second image data based on a plurality of first image data. Further, the third image data generator 126 may generate a plurality of third image data based on a plurality of second image data. In this case, by selecting one second image data and/or one third image data from a plurality of second image data and/or a plurality of third image data, the decoration used for producing the decorative molded product 1 A decorative sheet 3 may be determined.
　また、成形型データ生成部１２２は、仮決定された複数の成形型に基づいて、複数の成形型データを生成してもよい。この場合、伸び表示画像データ生成部１２４及び第２画像データ生成部１２５は、複数の成形型データに基づいて、複数の伸び表示画像データ及び複数の第２画像データを生成してもよい。また、第３画像データ生成部１２６は、複数の第２画像データに基づいて、複数の第３画像データを生成してもよい。そして、複数の第２画像データ及び／又は複数の第３画像データから一の第２画像データ及び／又は一の第３画像データを選択することにより、加飾成形品１の作製に用いる成形型を決定してもよい。 Further, the molding die data generation unit 122 may generate a plurality of molding die data based on the plurality of tentatively determined molding dies. In this case, the stretched display image data generator 124 and the second image data generator 125 may generate a plurality of stretched display image data and a plurality of second image data based on a plurality of molding die data. Further, the third image data generator 126 may generate a plurality of third image data based on a plurality of second image data. Then, by selecting one second image data and/or one third image data from a plurality of second image data and/or a plurality of third image data, a molding die used for producing the decorative molded product 1 may be determined.
　また、伸び表示画像データ生成部１２４は複数の成形型データに基づいて複数の伸び表示画像データを生成し、第２画像データ生成部１２５は、複数の成形型データ及び複数の第１画像データに基づいて複数の第２画像データを生成してもよい。また、第３画像データ生成部１２６は、複数の第２画像データに基づいて複数の第３画像データを生成してもよい。この場合、複数の第２画像データ及び／又は複数の第３画像データから一の第２画像データ及び／又は一の第３画像データを選択することにより、加飾成形品１の作製に用いる加飾シート３及び成形型１０を決定してもよい。 Further, the stretch display image data generation unit 124 generates a plurality of stretch display image data based on a plurality of molding die data, and the second image data generation unit 125 generates a plurality of molding die data and a plurality of first image data. A plurality of second image data may be generated based on. Further, the third image data generator 126 may generate a plurality of third image data based on a plurality of second image data. In this case, by selecting one second image data and/or one third image data from a plurality of second image data and/or a plurality of third image data, the decoration used for producing the decorative molded product 1 The decorative sheet 3 and the mold 10 may be determined.
　図２２は、一つの成形型データ及び複数の第１画像データに基づいて生成された複数の第３画像データから一の第３画像データを選択することにより、加飾成形品１の作製に用いる加飾シート３及び成形型１０を決定する、加飾成形品１の製造方法を示すフローチャートである。 FIG. 22 shows that one third image data is selected from a plurality of third image data generated based on one molding die data and a plurality of first image data, and is used for producing the decorative molded product 1. 3 is a flow chart showing a method for manufacturing a decorative molded product 1, in which a decorative sheet 3 and a mold 10 are determined.
　図２２に示す製造方法では、まず、成形品データ並びに一の第１画像データ及び他の第１画像データを生成又は取得し、記憶部１２１に格納する（ステップＳ２１１）。一の第１画像データが表す加飾シート３の絵柄と他の第１画像データが表す加飾シート３の絵柄は、互いに異なる。次に、成形品データに基づいて１つの成形型１０を仮決定する（ステップＳ２１２）。次に、成形型データ生成部１２２において、仮決定された成形型１０の三次元形状を表す成形型データを１つ生成する（ステップＳ２１３）。次に、演算部１２３において、成形型データに基づいて、仮決定された成形型１０で加飾シート３を成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを算出する（ステップＳ２１４）。次に、伸び表示画像データ生成部１２４において伸び表示画像データを生成し、表示部１２７に表示する（ステップＳ２１５）。表示部１２７に表示された伸び表示画像データに基づいて、成形後の加飾シート３の伸びを評価する（ステップＳ２１６）。仮決定された成形型１０で成形後の加飾シート３の各部の伸びが予め決めた閾値以下である場合（ステップＳ２１６の「Ｙｅｓ」）、第２画像データ生成部１２５において、一の第２画像データ及び他の第２画像データを生成する（ステップＳ２１７）。一の第２画像データは、成形型データ及び一の第１画像データに基づいて生成された第２画像データである。また、他の第２画像データは、成形型データ及び他の第１画像データに基づいて生成された第２画像データである。次に、第３画像データ生成部１２６において、一の第２画像データから一の第３画像データを生成し、また、他の第２画像データから他の第３画像データを生成する。一の第３画像データは、一の第２画像データが表す加飾シート３のうち、第１領域１３１のみを表す画像データである。また、他の第３画像データは、他の第２画像データが表す加飾シート３のうち、第１領域１３１のみを表す画像データである。そして、一の第３画像データ及び他の第３画像データを表示部１２７に表示する（ステップＳ２１８）。表示部１２７に表示された第３画像データに基づいて、一の第３画像データ及び他の第３画像データが表す加飾シート３の第１領域１３１の全体評価を行い、一の第３画像データ及び他の第３画像データのいずれかを選択する。選択した第３画像データに基づいて、加飾成形品１の作製に用いる加飾シート３及び成形型１０を決定する（ステップＳ２１９）。その後、ステップＳ２１９で決定された成形型１０を作製し、作製された成形型１０とステップＳ２１９で決定された加飾シート３とを用いて加飾成形品１を製造する。 In the manufacturing method shown in FIG. 22, first, molded product data, one first image data, and other first image data are generated or acquired, and stored in the storage unit 121 (step S211). The pattern of the decorative sheet 3 represented by one first image data and the pattern of the decorative sheet 3 represented by the other first image data are different from each other. Next, one molding die 10 is tentatively determined based on the molded product data (step S212). Next, the molding die data generator 122 generates one piece of molding die data representing the three-dimensional shape of the tentatively determined molding die 10 (step S213). Next, in the calculation unit 123, each part of the decorated sheet 3 after molding with respect to the decorated sheet 3 before molding when molding the decorative sheet 3 with the molding die 10 temporarily determined based on the molding die data is calculated (step S214). Next, the expanded display image data is generated in the expanded display image data generation unit 124 and displayed on the display unit 127 (step S215). The elongation of the decorative sheet 3 after molding is evaluated based on the elongation display image data displayed on the display unit 127 (step S216). When the elongation of each part of the decorative sheet 3 after molding by the temporarily determined molding die 10 is equal to or less than the predetermined threshold value ("Yes" in step S216), the second image data generation unit 125 generates one second Image data and other second image data are generated (step S217). The piece of second image data is second image data generated based on the molding die data and the piece of first image data. Further, the other second image data is the second image data generated based on the molding die data and the other first image data. Next, in the third image data generator 126, one third image data is generated from one second image data, and other third image data is generated from other second image data. One third image data is image data representing only the first region 131 of the decorative sheet 3 represented by one second image data. Further, the other third image data is image data representing only the first region 131 of the decorative sheet 3 represented by the other second image data. Then, the one third image data and the other third image data are displayed on the display unit 127 (step S218). Based on the third image data displayed on the display unit 127, the overall evaluation of the first region 131 of the decorative sheet 3 represented by the one third image data and the other third image data is performed, and the one third image is evaluated. data and other third image data. Based on the selected third image data, the decorative sheet 3 and mold 10 to be used for manufacturing the decorative molded product 1 are determined (step S219). After that, the molding die 10 determined in step S219 is produced, and the decorated molding 1 is manufactured using the molding die 10 thus produced and the decorative sheet 3 determined in step S219.
　ステップＳ２１６において成形後の加飾シート３のいずれかの部分の伸びが上記閾値よりも大きい場合（ステップＳ２１６の「Ｎｏ」）、ステップＳ２１２に戻り、再び成形型の仮決定を行う。具体的には、ステップＳ２１６を実施する前にステップＳ２１２で仮決定された成形型を変更又は修正する。その後、変更又は修正された成形型に基づいて、ステップＳ２１３以降の処理を繰り返す。 In step S216, if the elongation of any portion of the decorative sheet 3 after molding is greater than the threshold value ("No" in step S216), the process returns to step S212, and the mold is tentatively determined again. Specifically, the mold tentatively determined in step S212 is changed or corrected before performing step S216. After that, the processing after step S213 is repeated based on the changed or corrected mold.
　なお、図２２に示す例では、ステップＳ２１９において、第３画像データに基づいて加飾シート３の第１領域１３１の全体評価を行っているが、これに限られない。ステップＳ２１９では、上記全体評価を、第２画像データに基づいて行ってもよい。上記全体評価を第２画像データに基づいて行う場合、第３画像データを生成しなくてもよい。すなわち、図２２のステップＳ２１８の処理を行わなくてもよい。 In the example shown in FIG. 22, in step S219, the overall evaluation of the first area 131 of the decorative sheet 3 is performed based on the third image data, but the present invention is not limited to this. In step S219, the overall evaluation may be performed based on the second image data. When performing the overall evaluation based on the second image data, the third image data need not be generated. That is, the process of step S218 in FIG. 22 may not be performed.
　図２３は、複数の成形型データ及び複数の第１画像データに基づいて生成された複数の第３画像データから一の第３画像データを選択することにより、加飾成形品１の作製に用いる加飾シート３及び成形型１０を決定する、加飾成形品１の製造方法を示すフローチャートである。 FIG. 23 shows that one third image data is selected from a plurality of third image data generated based on a plurality of molding die data and a plurality of first image data, and used for producing the decorative molded product 1. 3 is a flow chart showing a method for manufacturing a decorative molded product 1, in which a decorative sheet 3 and a mold 10 are determined.
　図２３に示す製造方法では、まず、成形品データ並びに一の第１画像データ及び他の第１画像データを生成又は取得し、記憶部１２１に格納する（ステップＳ２２１）。一の第１画像データが表す加飾シート３の意匠と他の第１画像データが表す加飾シート３の意匠は、互いに異なる。 In the manufacturing method shown in FIG. 23, first, molded product data, one first image data, and other first image data are generated or acquired, and stored in the storage unit 121 (step S221). The design of the decorative sheet 3 represented by one first image data and the design of the decorative sheet 3 represented by the other first image data are different from each other.
　次に、一の第１画像データが表す加飾シート３用に、成形品データに基づいて一の成形型１０を仮決定する（ステップＳ２２２）。次に、成形型データ生成部１２２において、仮決定された一の成形型１０の三次元形状を表す一の成形型データを生成する（ステップＳ２２３）。次に、演算部１２３において、一の成形型データに基づいて、仮決定された一の成形型１０で加飾シート３を成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを算出する（ステップＳ２２４）。次に、伸び表示画像データ生成部１２４において、一の成形型データに基づいて算出された加飾シート３の各部の伸びを表す一の伸び表示画像データを生成し、表示部１２７に表示する（ステップＳ２２５）。表示部１２７に表示された一の伸び表示画像データに基づいて、成形後の加飾シート３の伸びを評価する（ステップＳ２２６）。仮決定された一の成形型１０で成形後の加飾シートの各部の伸びが予め決めた閾値以下である場合（ステップＳ２２６の「Ｙｅｓ」）、第２画像データ生成部１２５において、一の成形型データ及び一の第１画像データに基づいて、一の第２画像データを生成する（ステップＳ２２７）。次に、第３画像データ生成部１２６において、一の第２画像データから一の第３画像データを生成し、表示部１２７に表示する（ステップＳ２２８）。 Next, one molding die 10 is tentatively determined based on the molded product data for the decorative sheet 3 represented by one first image data (step S222). Next, the molding die data generator 122 generates one molding die data representing the three-dimensional shape of the tentatively determined one molding die 10 (step S223). Next, in the calculation unit 123, when the decorative sheet 3 is molded with the temporarily determined one molding die 10 based on the one molding die data, the post-molding decoration of the pre-molding decoration sheet 3 is performed. The elongation of each portion of the seat 3 is calculated (step S224). Next, the elongation display image data generation unit 124 generates one elongation display image data representing the elongation of each part of the decorative sheet 3 calculated based on one molding die data, and displays it on the display unit 127 ( step S225). The elongation of the decorative sheet 3 after molding is evaluated based on the one elongation display image data displayed on the display unit 127 (step S226). If the elongation of each part of the decorative sheet after being molded by the temporarily determined one molding die 10 is equal to or less than the predetermined threshold value (“Yes” in step S226), the second image data generation unit 125 performs one molding A piece of second image data is generated based on the type data and the piece of first image data (step S227). Next, the third image data generation unit 126 generates one third image data from the one second image data and displays it on the display unit 127 (step S228).
　ステップＳ２２６において成形後の加飾シート３のいずれかの部分の伸びが上記閾値よりも大きい場合（ステップＳ２２６の「Ｎｏ」）、ステップＳ２２２に戻り、再び一の成形型の仮決定を行う。具体的には、ステップＳ２２６を実施する前にステップＳ２２２で仮決定された一の成形型を変更又は修正する。その後、変更又は修正された一の成形型に基づいて、ステップＳ２２３～Ｓ２２６の処理を繰り返す。 In step S226, if the elongation of any part of the decorative sheet 3 after molding is greater than the threshold value ("No" in step S226), the process returns to step S222 to tentatively determine one molding die again. Specifically, the one molding die provisionally determined in step S222 is changed or corrected before performing step S226. After that, the processing of steps S223 to S226 is repeated based on the changed or modified single mold.
　また、他の第１画像データが表す加飾シート３用に、成形品データに基づいて、一の成形型１０とは異なる他の成形型１０を仮決定する（ステップＳ２３２）。次に、成形型データ生成部１２２において、仮決定された他の成形型１０の三次元形状を表す他の成形型データを生成する（ステップＳ２３３）。次に、演算部１２３において、他の成形型データに基づいて、仮決定された他の成形型１０で加飾シート３を成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを算出する（ステップＳ２３４）。次に、伸び表示画像データ生成部１２４において、他の成形型データに基づいて算出された加飾シート３の各部の伸びを表す他の伸び表示画像データを生成し、表示部１２７に表示する（ステップＳ２３５）。表示部１２７に表示された他の伸び表示画像データに基づいて、成形後の加飾シート３の伸びを評価する（ステップＳ２３６）。仮決定された他の成形型１０で成形後の加飾シートの各部の伸びが予め決めた閾値以下である場合（ステップＳ２３６の「Ｙｅｓ」）、第２画像データ生成部１２５において、他の成形型データ及び他の第１画像データに基づいて、他の第２画像データを生成する（ステップＳ２３７）。次に、第３画像データ生成部１２６において、他の第２画像データから他の第３画像データを生成し、表示部１２７に表示する（ステップＳ２３８）。 Also, for the decorative sheet 3 represented by the other first image data, another molding die 10 different from the one molding die 10 is tentatively determined based on the molding data (step S232). Next, the molding die data generation unit 122 generates other molding die data representing the three-dimensional shape of the tentatively determined other molding die 10 (step S233). Next, in the calculation unit 123, based on the other molding die data, when the decorative sheet 3 is molded with the other molding die 10 temporarily determined, the post-molding decoration for the pre-molding decoration sheet 3 is calculated. The elongation of each portion of the seat 3 is calculated (step S234). Next, the elongation display image data generation unit 124 generates other elongation display image data representing the elongation of each part of the decorative sheet 3 calculated based on other molding die data, and displays it on the display unit 127 ( step S235). Based on other elongation display image data displayed on the display unit 127, the elongation of the decorative sheet 3 after molding is evaluated (step S236). If the elongation of each part of the decorative sheet after being molded by the tentatively determined other mold 10 is equal to or less than the predetermined threshold value ("Yes" in step S236), the second image data generation unit 125 performs another molding. Other second image data is generated based on the type data and other first image data (step S237). Next, the third image data generation unit 126 generates another third image data from the other second image data, and displays it on the display unit 127 (step S238).
　ステップＳ２３６において成形後の加飾シート３のいずれかの部分の伸びが上記閾値よりも大きい場合（ステップＳ２３６の「Ｎｏ」）、ステップＳ２３２に戻り、再び他の成形型の仮決定を行う。具体的には、ステップＳ２３６を実施する前にステップＳ２３２で仮決定された他の成形型を変更又は修正する。その後、変更又は修正された他の成形型に基づいて、ステップＳ２３３～Ｓ２３６の処理を繰り返す。 In step S236, if the elongation of any part of the decorative sheet 3 after molding is greater than the threshold value ("No" in step S236), the process returns to step S232 to tentatively determine another molding die. Specifically, the other mold tentatively determined in step S232 is changed or corrected before performing step S236. After that, the processing of steps S233 to S236 is repeated based on other changed or modified molds.
　次に、表示部１２７に表示された一の第３画像データ及び他の第３画像データに基づいて、一の第３画像データ及び他の第３画像データが表す加飾シート３の第１領域１３１の全体評価を行い、一の第３画像データ及び他の第３画像データのいずれかを選択する。選択した第３画像データに基づいて、加飾成形品１の作製に用いる加飾シート３及び成形型１０を決定する（ステップＳ２２９）。その後、ステップＳ２２９で決定された成形型１０を作製し、作製された成形型１０とステップＳ２２９で決定された加飾シート３とを用いて加飾成形品１を製造する。 Next, based on the one third image data and the other third image data displayed on the display unit 127, the first region of the decorative sheet 3 represented by the one third image data and the other third image data is displayed. 131 global evaluations are performed to select between one third image data and another third image data. Based on the selected third image data, the decorative sheet 3 and mold 10 to be used for manufacturing the decorative molded product 1 are determined (step S229). After that, the mold 10 determined in step S229 is manufactured, and the decorated molded product 1 is manufactured using the manufactured mold 10 and the decorative sheet 3 determined in step S229.
　なお、図２３に示す例では、ステップＳ２２９において、第３画像データに基づいて加飾シート３の第１領域１３１の全体評価を行っているが、これに限られない。ステップＳ２２９では、上記全体評価を、第２画像データに基づいて行ってもよい。上記全体評価を第２画像データに基づいて行う場合、第３画像データを生成しなくてもよい。すなわち、図２３のステップＳ２２８及びＳ２３８の処理を行わなくてもよい。 Note that in the example shown in FIG. 23, in step S229, the overall evaluation of the first area 131 of the decorative sheet 3 is performed based on the third image data, but the present invention is not limited to this. In step S229, the overall evaluation may be performed based on the second image data. When performing the overall evaluation based on the second image data, the third image data need not be generated. That is, the processing of steps S228 and S238 in FIG. 23 may not be performed.
　上述してきた第２の実施形態に対する更に他の変更として、例えば、第１画像データが表す加飾シート３が、その表面にエンボス加工が施されていてマットな質感を有する場合、あるいは、加飾シート３が、その表面の艶を低下させる材料（例えば、マットな質感を有する材料）で作製されている場合、第２画像データ生成部１２５は、加飾シート３のうち、伸びの大きい領域が伸びの小さい領域よりも高い艶を出しているように見えるよう、第２画像データを生成してもよい。 As still another modification to the above-described second embodiment, for example, the decorative sheet 3 represented by the first image data may be embossed on its surface to have a matte texture, or When the sheet 3 is made of a material that reduces the luster of the surface (for example, a material having a matte texture), the second image data generation unit 125 determines that the area of the decorative sheet 3 that is highly stretched is The second image data may be generated such that areas of low elongation appear to have a higher gloss.
　また、別の見方によれば、加飾シート３の各部が伸びる事象は、加飾シート３の膜厚が薄くなる事象であると捉えることもできる。これによれば、例えば、第１画像データが表す加飾シート３が光を透過させる材料で作製されている場合、第２画像データ生成部１２５は、加飾シート３のうち、伸びの大きい領域が伸びの小さい領域よりも明るく見えるよう、第２画像データを生成してもよい。 Also, from another point of view, the phenomenon that each part of the decorative sheet 3 is stretched can be regarded as the phenomenon that the film thickness of the decorative sheet 3 is reduced. According to this, for example, when the decorative sheet 3 represented by the first image data is made of a material that allows light to pass through, the second image data generation unit 125 generates a region of the decorative sheet 3 with a large elongation. The second image data may be generated such that the region appears brighter than the less stretched region.
　さらに、例えば、第１画像データが表す加飾シートに、光の透過を促進させる複数の透過孔が、加飾シート３の平面視において均一な密度で形成されている場合について考える。この場合、加飾シート３のうち、伸びの大きい領域の透過孔の開口面積が伸びの小さい領域の透過孔の開口面積よりも大きくなると考えられるときは、第２画像データ生成部１２５は、加飾シート３のうち、伸びの大きい領域が伸びの小さい領域よりも明るく見えるよう、第２画像データを生成してもよい。一方、加飾シート３のうち、伸びの大きい領域の透過孔の密度が伸びの小さい領域の透過孔の密度よりも低くなると考えられるときは、第２画像データ生成部１２５は、加飾シート３のうち、伸びの大きい領域が伸びの小さい領域よりも暗く見えるよう、第２画像データを生成してもよい。 Further, for example, consider a case where the decorative sheet represented by the first image data is formed with a plurality of transmission holes that promote the transmission of light with a uniform density in plan view of the decorative sheet 3 . In this case, when it is considered that the opening area of the transmission holes in the region of the decorative sheet 3 with high elongation is larger than the opening area of the transmission holes in the region of low elongation, the second image data generation unit 125 The second image data may be generated so that the areas of the decorative sheet 3 that are stretched more appear brighter than the areas that are stretched less. On the other hand, when it is considered that the density of the transmission holes in the region of the decorative sheet 3 with high elongation is lower than the density of the transmission holes in the region of the low elongation, the second image data generation unit 125 The second image data may be generated so that the region with the larger stretch appears darker than the region with the smaller stretch.
　以上に説明してきた第２の実施形態による評価方法は、成形された加飾シート３を含む加飾成形品１を作製する際の、成形前の加飾シート３に対する成形後の加飾シート３の絵柄の変形を評価する方法である。第２の実施形態による評価方法は、加飾成形品１の三次元形状を表す成形品データを生成又は取得する工程と、成形品データに基づいて加飾シート３の成形に用いられる成形型１０を仮決定する工程と、仮決定された成形型１０の三次元形状を表す成形型データを生成する工程と、成形前の加飾シート３を表す第１画像データを生成又は取得する工程と、加飾シート３を仮決定された成形型１０で成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを、成形型データに基づいて算出する工程と、算出した加飾シート３の各部の伸びと第１画像データとに基づいて、仮決定された成形型で成形後の加飾シート３を表す第２画像データを生成する工程と、を備えている。第１画像データは、絵柄を有する加飾シート３を表す。第２画像データは、第１画像データが表す成形前の加飾シート３の絵柄を、算出した加飾シート３の各部の伸びに応じて変形させることにより生成される。第２の実施形態の評価方法によれば、加飾成形品１を作製する際の加飾シート３の絵柄の変形を、成形型１０や加飾成形品１を作製することなく評価することができる。これにより、実際に作製される加飾成形品１に意図した意匠と異なる意匠が付与される虞を抑制しつつ、加飾成形品１の作製にかかる時間及びコストを低減させることができる。 In the evaluation method according to the second embodiment described above, when the decorative molded product 1 including the molded decorative sheet 3 is produced, the decorative sheet 3 after molding is compared with the decorative sheet 3 before molding. This is a method of evaluating the deformation of the pattern of The evaluation method according to the second embodiment includes a step of generating or acquiring molded product data representing the three-dimensional shape of the decorative molded product 1, and a molding die 10 used for molding the decorative sheet 3 based on the molded product data. a step of tentatively determining, a step of generating molding die data representing the three-dimensional shape of the tentatively determined molding die 10, a step of generating or acquiring first image data representing the decorative sheet 3 before molding, a step of calculating the elongation of each part of the decorated sheet 3 after molding with respect to the decorated sheet 3 before molding based on molding die data when molding the decorative sheet 3 with the molding die 10 that has been temporarily determined; and generating second image data representing the decorative sheet 3 after molding with the temporarily determined mold based on the calculated elongation of each part of the decorative sheet 3 and the first image data. . The first image data represents the decorative sheet 3 having a pattern. The second image data is generated by deforming the pattern of the decorating sheet 3 before molding represented by the first image data according to the calculated elongation of each part of the decorating sheet 3 . According to the evaluation method of the second embodiment, the deformation of the pattern of the decorative sheet 3 when producing the decorative molded product 1 can be evaluated without producing the molding die 10 and the decorative molded product 1. can. As a result, it is possible to reduce the time and cost required to manufacture the decorative molded product 1 while suppressing the possibility that a design different from the intended design is imparted to the actually manufactured decorative molded product 1 .
　また、以上に説明してきた第２の実施形態の評価方法は、仮決定された成形型１０で成形後の加飾シート３の各部と算出した加飾シート３の各部の伸びとの対応関係を視覚的に表す伸び表示画像データを生成する工程を更に備えている。例えば、伸び表示画像データは、算出した加飾シート３の各部の伸びを、当該伸びの大きさに応じた色で表す。或いは、伸び表示画像データは、算出した加飾シート３の各部の伸びを、当該伸びの大きさに応じた線の歪みで表す。これにより、仮決定された成形型１０で成形した加飾シート３の各部と算出した加飾シート３の各部の伸びとの対応関係を、容易に把握することができる。 In addition, the evaluation method of the second embodiment described above determines the correspondence relationship between each part of the decorative sheet 3 after molding with the temporarily determined mold 10 and the calculated elongation of each part of the decorative sheet 3. The step of generating stretched display image data that is visually represented is further provided. For example, the elongation display image data represents the calculated elongation of each part of the decorative sheet 3 in a color corresponding to the magnitude of the elongation. Alternatively, the elongation display image data represents the calculated elongation of each part of the decorative sheet 3 by a distortion of a line corresponding to the magnitude of the elongation. Accordingly, it is possible to easily grasp the correspondence relationship between each part of the decorative sheet 3 formed by the temporarily determined molding die 10 and the calculated elongation of each part of the decorative sheet 3 .
　また、以上に説明してきた第２の実施形態において、加飾成形品１は、互いに対する傾斜角度θが４５°以上である２つの面１ａ，１ｂが接続する接続領域１ｃを含む。このような加飾成形品１において一方の面１ａから他方の面１ｂに亘って加飾シート３適用される場合、接続領域１ｃにおいて、加飾シート３は著しく伸長する傾向にある。このように加飾シート３が著しく伸長する領域を加飾成形品１が含む場合、伸長による加飾シート３の絵柄の変形を予測することは難しい。しかしながら、第２の実施形態の評価方法によれば、加飾成形品１を作製する際の加飾シート３の絵柄の変形を、成形型１０や加飾成形品１を作製することなく評価することができる。この場合、第２の実施形態による評価方法は、第２画像データを表示部１２７に表示する工程を更に備えていてもよく、表示部１２７において、第２画像データは、加飾シート３の上記２つの面１ａ，１ｂ及び接続領域１ｃに適用される領域を表してよい。これにより、接続領域１ｃにおける加飾シート３の絵柄の変形を、容易に把握することができる。 In addition, in the second embodiment described above, the decorative molded product 1 includes a connection region 1c where two surfaces 1a and 1b having an inclination angle θ of 45° or more with respect to each other are connected. When the decorative sheet 3 is applied from one surface 1a to the other surface 1b of such a decorative molded product 1, the decorative sheet 3 tends to stretch significantly in the connection region 1c. When the decorative molded product 1 includes a region where the decorative sheet 3 is remarkably elongated, it is difficult to predict the deformation of the design of the decorative sheet 3 due to the expansion. However, according to the evaluation method of the second embodiment, the deformation of the pattern of the decorative sheet 3 when producing the decorative molded product 1 is evaluated without producing the mold 10 and the decorative molded product 1. be able to. In this case, the evaluation method according to the second embodiment may further include a step of displaying the second image data on the display unit 127 . It may represent the area applied to the two faces 1a, 1b and the connection area 1c. Thereby, the deformation of the pattern of the decorative sheet 3 in the connection area 1c can be easily grasped.
　また、以上に説明してきた第２の実施形態の評価方法は、第２画像データを表示部１２７に表示する工程を更に備えている。そして、表示部１２７において、第２画像データが表す加飾シート３を並進、回転、拡大及び／又は縮小可能である。この場合、加飾成形品１を実際に手に取って観察する場合と同様に、加飾シート３を観察することができる。 In addition, the evaluation method of the second embodiment described above further includes a step of displaying the second image data on the display unit 127 . Then, on the display unit 127, the decorative sheet 3 represented by the second image data can be translated, rotated, enlarged and/or reduced. In this case, the decorative sheet 3 can be observed in the same manner as when the decorative molded article 1 is actually picked up and observed.
　また、以上に説明してきた第２の実施形態において、第１画像データが着色された加飾シート３を表す場合、第２画像データは、第１画像データが示す成形前の加飾シート３の各部の色を、算出した加飾シート３の各部の伸びに応じた色に変更することにより、生成される。これにより、仮決定された成形型１０で成形した加飾シート３によって表される意匠を、容易に把握することができる。 Further, in the second embodiment described above, when the first image data represents the colored decorative sheet 3, the second image data represents the unmolded decorative sheet 3 indicated by the first image data. It is generated by changing the color of each part to a color corresponding to the calculated elongation of each part of the decorative sheet 3 . Thereby, the design represented by the decorative sheet 3 molded with the mold 10 that has been provisionally determined can be easily grasped.
　また、以上に説明してきた第２の実施形態において、第２画像データにより表される成形後の加飾シート３は、加飾成形品１の一部として用いられる第１領域１３１と、第１領域１３１以外の第２領域１３２と、を含んでいる。第２の実施形態の評価方法は、第２画像データに基づいて、第１領域１３１のみを表す第３画像データを生成する工程を更に備えている。これにより、加飾シート３によって加飾成形品１に付与される意匠を、容易に把握することができる。 Further, in the second embodiment described above, the molded decorative sheet 3 represented by the second image data includes the first region 131 used as a part of the decorative molded product 1 and the first and a second region 132 other than the region 131 . The evaluation method of the second embodiment further comprises the step of generating third image data representing only the first region 131 based on the second image data. Thereby, the design given to the decorative molded product 1 by the decorative sheet 3 can be easily grasped.
　また、以上に説明してきた第２の実施形態の評価方法は、第３画像データを表示部１２７に表示する工程を更に備えている。また、加飾成形品１は、互いに対する傾斜角度θが４５°以上である２つの面１ａ，１ｂが接続する接続領域１ｃを含む。そして、表示部１２７において、第３画像データは、加飾シート３の２つの面１ａ，１ｂ及び接続領域１ｃに適用される領域を表す。この場合、加飾成形品１の一方の面１ａから他方の面１ｂに亘って加飾シート３適用されると、接続領域１ｃにおいて、加飾シート３は著しく伸長する傾向にある。このように加飾シート３が著しく伸長する領域を加飾成形品１が含む場合、伸長による加飾シート３の絵柄の変形を予測することは難しい。しかしながら、第２の実施形態の評価方法によれば、接続領域１ｃにおける加飾シート３の絵柄の変形を、容易に把握することができる。 In addition, the evaluation method of the second embodiment described above further includes a step of displaying the third image data on the display unit 127 . The decorative molded product 1 also includes a connection region 1c where two surfaces 1a and 1b having an inclination angle θ of 45° or more with respect to each other are connected. In the display section 127, the third image data represents areas applied to the two surfaces 1a and 1b of the decorative sheet 3 and the connection area 1c. In this case, when the decorative sheet 3 is applied from one side 1a to the other side 1b of the decorative molded product 1, the decorative sheet 3 tends to stretch significantly in the connection region 1c. When the decorative molded product 1 includes a region where the decorative sheet 3 is remarkably elongated, it is difficult to predict the deformation of the design of the decorative sheet 3 due to the expansion. However, according to the evaluation method of the second embodiment, it is possible to easily grasp the deformation of the pattern of the decorative sheet 3 in the connection area 1c.
　また、以上に説明してきた第２の実施形態の評価方法は、第３画像データを表示部１２７に表示する工程を更に備えている。そして、表示部１２７において、第３画像データが表す加飾シート３を並進、回転、拡大及び／又は縮小可能である。この場合、加飾成形品１を実際に手に取って観察する場合と同様に、加飾シート３を観察することができる。 In addition, the evaluation method of the second embodiment described above further includes a step of displaying the third image data on the display unit 127 . Then, on the display unit 127, the decorative sheet 3 represented by the third image data can be translated, rotated, enlarged and/or reduced. In this case, the decorative sheet 3 can be observed in the same manner as when the decorative molded article 1 is actually picked up and observed.
　また、以上に説明してきた第２の実施形態による評価装置１２０は、成形された加飾シート３を含む加飾成形品１を作製する際の、成形前の加飾シート３に対する成形後の加飾シート３の絵柄の変形を評価する装置である。第２の実施形態の評価装置１２０は、加飾成形品１の三次元形状を表す成形品データ及び成形前の加飾シート３を表す第１画像データを格納する記憶部１２１と、成形品データに基づいて加飾シート３の成形に用いられる成形型として仮決定された成形型１０の三次元形状を表す成形型データを生成する成形型データ生成部１２２と、加飾シート３を仮決定された成形型１０で成形する場合における、成形前の加飾シート３に対する成形後の加飾シート３の各部の伸びを、成形型データに基づいて算出する演算部１２３と、算出した加飾シート３の各部の伸びと第１画像データとに基づいて、仮決定された成形型で成形後の加飾シート３を表す第２画像データを生成する第２画像データ生成部１２５と、を備えている。第２の実施形態の評価装置１２０によれば、加飾成形品１を作製する際の加飾シート３の絵柄の変形を、成形型１０や加飾成形品１を作製することなく評価することができる。これにより、実際に作製される加飾成形品１に意図した意匠と異なる意匠が付与される虞を抑制しつつ、加飾成形品１の作製にかかる時間及びコストを低減させることができる。 Further, the evaluation device 120 according to the second embodiment described above can be used for post-molding processing of the pre-molded decorative sheet 3 when producing the decorative molded product 1 including the molded decorative sheet 3 . This is a device for evaluating the deformation of the pattern of the decorative sheet 3 .
