Description

本発明は、偽造防止効果を必要とするセキュリティ印刷物である銀行券、パスポート、有価証券、身分証明書、カード、通行券等の個別識別を必要とする貴重印刷物の分野において、改ざんや偽造を防止するための立体模様印刷物及び立体模様印刷物の作製方法に関する。 The present invention prevents falsification and counterfeiting in the field of valuable printed materials that require individual identification such as banknotes, passports, securities, identification cards, cards, and pass tickets, which are security printed materials that require anti-counterfeiting effects. The present invention relates to a three-dimensional patterned printed matter and a method for producing the three-dimensional patterned printed matter.

従来、銀行券、株券、有価証券、通行券、カード等の偽造、変造を防止する必要性のある貴重印刷物においては、視覚的な偽造防止効果を与えるため、券面の背景画像等の一部又は複数の箇所に偽造防止用のレリーフ模様を付与することが多い。このレリーフ模様は、立体的に何らかのモチーフを二次元平面に表現する模様である。レリーフ模様は、一般的に証券印刷物等のデザインに広く用いられている地紋、彩紋及び模様等を構成するため作成される複数の画線からなる万線パターンから形成される。そして、画線の一部を屈曲させることで、画線ピッチが狭くなる部分で模様の影（暗）を表現し、画線ピッチが広くなる部分で光（明）を表現している。 Conventionally, for valuable printed materials such as banknotes, stock certificates, securities, passes, cards, etc. that need to be prevented from being forged or altered, a part of the background image of the face of the note or Relief patterns are often added to multiple locations to prevent forgery. This relief pattern is a pattern that expresses some kind of three-dimensional motif on a two-dimensional plane. A relief pattern is generally formed from a parallel line pattern made up of a plurality of drawing lines created to constitute a background pattern, color pattern, pattern, etc., which are generally widely used in the design of securities printed materials and the like. By bending a part of the drawing lines, the shadow (darkness) of the pattern is expressed in the part where the drawing pitch is narrow, and the light (brightness) is expressed in the part where the drawing pitch is wide.

また、近年では、モチーフをより立体的に視認させることが求められている。モチーフを立体的に視認させる技術としては、例えば、特許文献１に記載されているようなものがある。特許文献１に記載された技術では、背景を形成する背景画線と模様部を形成する模様画線をなくして模様部の「明」を表現し、背景画線の端部と模様画線の端部を互いに挟み込むように配置すること模様部の「暗」を表現している。 Furthermore, in recent years, there has been a demand for making motifs more three-dimensionally visible. As a technique for making a motif visible three-dimensionally, there is, for example, the one described in Patent Document 1. In the technique described in Patent Document 1, the background drawing line forming the background and the pattern drawing line forming the pattern part are eliminated to express the "brightness" of the pattern part, and the edge of the background drawing line and the pattern drawing line are By arranging the ends so that they are sandwiched together, the "darkness" of the pattern is expressed.

しかしながら、特許文献１に記載された技術では、模様に当たる光の加減を明部と暗部の２つ階層でしか表現することができなかったため、例え球体状のようなさらなる立体感が必要なモチーフを表現することが困難であった。 However, with the technology described in Patent Document 1, it was only possible to express the amount of light hitting the pattern in two layers: bright and dark areas. It was difficult to express.

本発明の目的は、上記の問題点を考慮し、立体感が増した模様部を有する立体模様印刷物及び立体模様印刷物の作製方法を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to take the above-mentioned problems into consideration and provide a three-dimensional patterned printed matter having a pattern portion with an increased three-dimensional effect, and a method for producing a three-dimensional patterned printed matter.

A parallel line consisting of a first three-dimensional pattern forming part formed of a line pattern, and a plurality of second drawing lines overlapping the first three-dimensional pattern forming part and arranged in a direction different from the arrangement direction of the plurality of first drawing lines. a second three-dimensional pattern forming section configured of a pattern, the first three-dimensional pattern forming section has a first background section forming a background, and the first background section and the first drawing line have different phases. The second three-dimensional pattern forming section has a first pattern section that forms a pattern, and the second three-dimensional pattern forming section has at least a thickness and an interval of a second background section that forms a background, and a second drawing line that forms the second background section. a second pattern portion that forms a pattern by being different from each other, the pattern portion is formed by overlapping the first pattern portion and the second pattern portion, and the background portion is formed by the first background portion and the second background portion. are formed by overlapping at least a portion of them.

また、立体模様印刷物の作製方法は、基材に複数の第１画線で形成した万線パターンにより構成された第１背景部と、第１背景部と第１画線の位相を異ならせて構成された第１模様部により、第１立体模様形成部を形成する工程と、第１背景部に少なくとも一部を重ね合わせて、第１画線と異なる配列方向の複数の第２画線で形成した万線パターンにより構成された第２背景部を形成し、第１模様部に重ね合わせて、第２背景部と第２画線の太さ及び間隔の少なくとも一つを異ならせて、第１模様部と同じ模様が構成された第２模様部を形成することで、第２立体模様形成部を形成する工程と、を有し、第１立体模様形成部と第２立体模様形成部が重なり合うことで、立体模様部が形成する。 In addition, a method for producing a three-dimensional pattern printed matter includes a first background portion constituted by a parallel line pattern formed of a plurality of first drawing lines on a base material, and a phase difference between the first background portion and the first drawing lines. a step of forming a first three-dimensional pattern forming portion using the configured first pattern portion; and a step of forming a first three-dimensional pattern forming portion by overlapping at least a portion of the first background portion with a plurality of second drawing lines in an arrangement direction different from the first drawing line. A second background part configured by the formed parallel line pattern is formed, is superimposed on the first pattern part, and at least one of the thickness and the interval between the second background part and the second drawing line is made different, and forming a second three-dimensional pattern forming part by forming a second pattern part having the same pattern as the first pattern part, the first three-dimensional pattern forming part and the second three-dimensional pattern forming part forming a second pattern forming part; By overlapping, a three-dimensional pattern is formed.

上記構成の立体模様印刷物及び立体模様印刷物の作製方法によれば、レリーフ模様である立体模様の明暗を画線のピッチ、太さ、配列方向といったが異なる構成の画線を重ね合わせることで、複数の段階で表現することが可能となる。よって、一つも模様内で明暗を細かく表現することができることから、従来より立体感が増した模様を提供することができ、例えば、球体状の模様を奥行き感があるように表現することができる。 According to the three-dimensional patterned printed matter and the method for producing three-dimensional patterned printed matter having the above configuration, the brightness and darkness of the three-dimensional pattern, which is a relief pattern, can be adjusted by overlapping a plurality of drawing lines with different configurations such as pitch, thickness, and arrangement direction. It becomes possible to express it at the stage of Therefore, since it is possible to precisely express the brightness and darkness within a single pattern, it is possible to provide a pattern with an increased sense of three-dimensionality than before, and for example, it is possible to express a spherical pattern with a sense of depth. .

１．実施の形態例
まず、実施の形態例（以下、「本例」という。）にかかる立体模様印刷物の構成について、図１及び図２を参照して説明する。
図１は、本例の立体模様印刷物を示す図である。 1. Embodiment Example First, the configuration of a three-dimensional pattern printed matter according to an embodiment example (hereinafter referred to as "this example") will be described with reference to FIGS. 1 and 2.

As shown in FIG. 1, the three-dimensional pattern printed matter 100 includes a base material 1 and a three-dimensional pattern section 10 that is a relief pattern formed on at least a portion of the base material 1. The three-dimensional pattern section 10 of this example uses a star shape and the alphabet "ABCD" as motifs. Note that the motif of the three-dimensional pattern portion 10 may be various other shapes such as a circle, a flower shape, a triangle shape, a spherical shape, etc., hiragana, katakana, Chinese numerals, symbols, etc.

次に、図２Ａから図２Ｃを参照して立体模様部１０の詳細な構成について説明する。
図２Ａは、立体模様部１０を構成する第１立体模様形成部２０を示す図であり、図２Ｂは、立体模様部１０を構成する第２立体模様形成部３０を示す図であり、図２Ｃは、立体模様部１０を示す図である。 Next, the detailed configuration of the three-dimensional pattern section 10 will be described with reference to FIGS. 2A to 2C.
FIG. 2A is a diagram showing the first three-dimensional pattern forming section 20 forming the three-dimensional pattern section 10, FIG. 2B is a view showing the second three-dimensional pattern forming section 30 forming the three-dimensional pattern section 10, and FIG. 2C is a drawing showing the second three-dimensional pattern forming section 30 forming the three-dimensional pattern section 10. 1 is a diagram showing a three-dimensional pattern section 10. FIG.

図２Ａから図２Ｃに示す立体模様部１０は、第１版面と第２版面の２つの版面を用いた合成模様（重合版）により構成されている。第１版面には、図２Ａに示す第１立体模様形成部２０が形成されており、第２版面には、図２Ｂに示す第２立体模様形成部３０が形成されている。そして、図２Ｃに示す立体模様部１０は、図２Ａに示す第１立体模様形成部２０と、図２Ｂに示す第２立体模様形成部３０を重ね合わせることで形成される。 The three-dimensional pattern section 10 shown in FIGS. 2A to 2C is composed of a composite pattern (polymerized plate) using two printing plates, a first printing plate and a second printing plate. A first three-dimensional pattern forming part 20 shown in FIG. 2A is formed on the first printing plate, and a second three-dimensional pattern forming part 30 shown in FIG. 2B is formed on the second printing plate. The three-dimensional pattern section 10 shown in FIG. 2C is formed by overlapping the first three-dimensional pattern forming section 20 shown in FIG. 2A and the second three-dimensional pattern forming section 30 shown in FIG. 2B.

図２Ａに示すように、第１立体模様形成部２０は、複数の直線状の画線である第１画線Ｌ２０で形成した万線パターンにより構成されている。第１立体模様形成部２０を構成する第１画線Ｌ２０は、配列方向である第１の方向Ｖ１に複数配置されている。 As shown in FIG. 2A, the first three-dimensional pattern forming section 20 is configured by a line pattern formed by first drawing lines L20 that are a plurality of linear drawing lines. A plurality of first drawing lines L20 constituting the first three-dimensional pattern forming section 20 are arranged in a first direction V1, which is an arrangement direction.

第１立体模様形成部２０は、背景を形成する第１背景部２１と、模様を形成する第１模様部２２とを有している。第１立体模様形成部２０は、第１背景部２１に対して第１画線Ｌ２０の位相を異なる位相にすることで第１模様部２２を表現しており、図２Ａでは星形状の模様とその周囲の背景を形成している。すなわち、第１立体模様形成部２０は、画線ピッチが広くなるところで「明」を表現し、画線ピッチが狭くなるところで「暗」を表現している。 The first three-dimensional pattern forming section 20 has a first background section 21 that forms a background, and a first pattern section 22 that forms a pattern. The first three-dimensional pattern forming part 20 expresses the first pattern part 22 by making the phase of the first drawing line L20 different from the first background part 21, and in FIG. 2A, a star-shaped pattern and It forms the background around it. That is, the first three-dimensional pattern forming unit 20 expresses "bright" where the line pitch becomes wide, and expresses "dark" where the line pitch becomes narrow.

なお、第１立体模様形成部２０の「明」と「暗」を強調するために、第１背景部２１と第１模様部２２の境界の第１画線Ｌ２０を一部太くしてもよい。例えば、図２Ａでは、第１背景部２１と第１模様部２２の境界において、第１背景部２１の右側に位置する第１画線Ｅ１１の一部を太くすることで、模様の影（暗）を強調する表現している。さらに、強調させる表現として、第１模様部２２の輪郭に画線を配置してもよい。例えば、図２Ａでは、第１模様部２２である４文字のアルファベットにおける１文字ごとに一部に輪郭を形成する画線Ｅ１２が形成されている。 Note that in order to emphasize the "brightness" and "darkness" of the first three-dimensional pattern forming part 20, the first drawing line L20 at the boundary between the first background part 21 and the first pattern part 22 may be partially thickened. . For example, in FIG. 2A, by thickening a part of the first drawing line E11 located on the right side of the first background part 21 at the boundary between the first background part 21 and the first pattern part 22, the shadow of the pattern (dark ) is expressed to emphasize. Furthermore, a drawing line may be placed on the outline of the first pattern portion 22 as an expression for emphasis. For example, in FIG. 2A, a drawing line E12 forming an outline is formed for each letter of the four-letter alphabet that is the first pattern portion 22.

図２Ｂに示すように、第２立体模様形成部３０は、第１立体模様形成部２０と同様に、複数の直線状の画線である第２画線Ｌ３０で形成した万線パターンにより構成されている。第２立体模様形成部３０を構成する第２画線Ｌ３０は、配列方向である第２の方向Ｖ２に複数配置されている。また、第２の方向Ｖ２は、第１の方向Ｖ１とは異なる方向を向いている。そのため、第２立体模様形成部３０を構成する第２画線Ｌ３０の配列方向は、第１立体模様形成部２０を構成する第１画線Ｌ２０の配列方向と異なる。 As shown in FIG. 2B, the second three-dimensional pattern forming section 30, like the first three-dimensional pattern forming section 20, is configured by a parallel line pattern formed by second drawing lines L30, which are a plurality of linear drawing lines. ing. A plurality of second drawing lines L30 constituting the second three-dimensional pattern forming section 30 are arranged in the second direction V2, which is the arrangement direction. Further, the second direction V2 faces a direction different from the first direction V1. Therefore, the arrangement direction of the second drawing lines L30 forming the second three-dimensional pattern forming section 30 is different from the arrangement direction of the first drawing lines L20 forming the first three-dimensional pattern forming section 20.

さらに、第２立体模様形成部３０を構成する第２画線Ｌ３０の色は特に限定はなく、第１立体模様形成部２０を構成する第２画線Ｌ２０の色と同じ色でも異なる色でもよい。なお、図２Ｂでは一例として異なる色に設定されている。 Further, the color of the second drawing line L30 constituting the second three-dimensional pattern forming section 30 is not particularly limited, and may be the same color as or a different color from the color of the second drawing line L20 constituting the first three-dimensional pattern forming section 20. . Note that in FIG. 2B, different colors are set as an example.

第２立体模様形成部３０は、背景を形成する第２背景部３１と、模様を形成する第２模様部３２とを有している。第２背景部３１を形成する第２画線Ｌ３０の太さ及びピッチの間隔は、第１背景部２１を形成する第１画線Ｌ２０の太さ及びピッチの間隔と同一である。なお、第１背景部２１を形成する第１画線Ｌ２０と第２背景部３１を形成する第２画線Ｌ３０を、互いに異なる太さやピッチの間隔にしてもよい。 The second three-dimensional pattern forming section 30 has a second background section 31 that forms a background, and a second pattern section 32 that forms a pattern. The thickness and pitch of the second drawing lines L30 forming the second background portion 31 are the same as the thickness and pitch of the first drawing lines L20 forming the first background portion 21. Note that the first drawing line L20 forming the first background portion 21 and the second drawing line L30 forming the second background portion 31 may have different thicknesses and pitches.

第２模様部３２は、第１模様部２２と同一の絵柄であり、図２Ｂでは一例として星形状としている。そして、第１立体模様形成部２０と第２立体模様形成部３０を重ね合わせた際に、第２模様部３２は、第１模様部２２と重なり合う位置に形成されている。 The second pattern portion 32 has the same pattern as the first pattern portion 22, and is in a star shape as an example in FIG. 2B. When the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30 are overlapped, the second pattern section 32 is formed at a position overlapping the first pattern section 22.

第２背景部３１は、第１背景部２１と図２Ｂでは同一の絵柄としているが、これに限らず異なる絵柄でもよい。同じ絵柄とした場合は、第１立体模様形成部２０と第２立体模様形成部３０を重ね合わせた際に、第２背景部３１は、第１背景部２１と重なり合う位置に形成されている。また、異なる絵柄とした場合は、第１立体模様形成部２０と第２立体模様形成部３０を重ね合わせた際に、第２背景部３１は、第１背景部２１と一部重なり合う位置に形成されている。 Although the second background portion 31 has the same pattern as the first background portion 21 in FIG. 2B, the pattern is not limited to this and may be a different pattern. In the case of the same pattern, when the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30 are overlapped, the second background section 31 is formed at a position overlapping with the first background section 21. In addition, when different patterns are used, when the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30 are overlapped, the second background section 31 is formed at a position where it partially overlaps the first background section 21. has been done.

また、第２立体模様形成部３０は、第２模様部３２の第２画線Ｌ３０の太さを、第２背景部３１の第２画線Ｌ３０の太さと異なる太さにすることで第２模様部３２を表現している。すなわち、第２立体模様形成部３０は、第２画線Ｌ３０が第２背景部３１よりも細くなるところで「明」を表現し、第２画線Ｌ３０が第２背景部３１よりも太くなるところで「暗」を表現している。 Further, the second three-dimensional pattern forming section 30 makes the thickness of the second drawing line L30 of the second pattern section 32 different from the thickness of the second drawing line L30 of the second background section 31. The pattern portion 32 is expressed. That is, the second three-dimensional pattern forming section 30 expresses "brightness" where the second drawing line L30 becomes thinner than the second background section 31, and where the second drawing line L30 becomes thicker than the second background section 31. It expresses "darkness".

なお、第２立体模様形成部３０は、第１立体模様形成部２０と同様に、「明」と「暗」を強調するために、第２背景部３１と第２模様部３２の境界の第２画線Ｌ３０を一部太くしてもよい。例えば、図２Ｂでは、第２背景部３１と第２模様部３２の境界において、第２背景部３１の右側に位置する第２画線Ｅ２１の一部を太くすることで、模様の影（暗）を強調する表現している。さらに、強調させる表現として、第２模様部３２の輪郭に画線を配置してもよい。 Note that, similarly to the first three-dimensional pattern forming section 20, the second three-dimensional pattern forming section 30 is arranged to Part of the two drawing lines L30 may be made thicker. For example, in FIG. 2B, by thickening a part of the second drawing line E21 located on the right side of the second background part 31 at the boundary between the second background part 31 and the second pattern part 32, the shadow of the pattern (dark ) is expressed to emphasize. Furthermore, drawing lines may be placed on the outline of the second pattern portion 32 to emphasize it.

上述した第１立体模様形成部２０と第２立体模様形成部３０を重ね合わせる工程を行うことで、図２Ｃに示すような、立体模様部１０が形成される。立体模様部１０は、背景部１１と、模様部１２とを有している。背景部１１は、図２Ａに示す第１背景部２１と、図２Ｂに示す第２背景部３１が重なり合うことで形成され、模様部１２は、図２Ａに示す第１模様部２２と、図２Ｂに示す第２模様部３２が重なり合うことで形成される。なお、図２Ａに示す第１立体模様形成部２０と第２立体模様形成部２０を重ね合わせる順番に特に限定はなく、どちらを上下に配置してもよい。 By performing the step of overlapping the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30 described above, the three-dimensional pattern section 10 as shown in FIG. 2C is formed. The three-dimensional pattern section 10 has a background section 11 and a pattern section 12. The background part 11 is formed by overlapping the first background part 21 shown in FIG. 2A and the second background part 31 shown in FIG. 2B, and the pattern part 12 is formed by overlapping the first background part 21 shown in FIG. 2A and the second background part 31 shown in FIG. 2B. It is formed by overlapping the second pattern portions 32 shown in FIG. Note that there is no particular limitation on the order in which the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 20 shown in FIG. 2A are overlapped, and either one may be arranged above or below.

上述したように、図２Ａに示す第１立体模様形成部２０を構成する第１画線Ｌ２０の配列方向と、図２Ｂに示す第２立体模様形成部３０を構成する第２画線Ｌ３０の配列方向は、互いに異なるため、図２Ｃに示すように、第１立体模様形成部２０の第１画線Ｌ２０と第２立体模様形成部３０の第２画線Ｌ３０は、交差する。 As described above, the arrangement direction of the first drawing lines L20 forming the first three-dimensional pattern forming section 20 shown in FIG. 2A and the arrangement direction of the second drawing lines L30 forming the second three-dimensional pattern forming section 30 shown in FIG. 2B are different from each other. Since the directions are different from each other, the first drawing line L20 of the first three-dimensional pattern forming section 20 and the second drawing line L30 of the second three-dimensional pattern forming section 30 intersect, as shown in FIG. 2C.

図２Ｃに示すように、模様部１２には、陰影部となる暗部１４と、光が当たる箇所となる明部１３が形成されている。図２Ａに示す第１立体模様形成部２０の「暗」を形成する領域と、図２Ｂに示す第２立体模様形成部３０の「暗」を形成する領域が重なり合うことで、図２Ａに示す第１立体模様形成部２０の「暗」及び図２Ｂに示す第２立体模様形成部３０の「暗」よりも暗い最暗部が、図２Ｃに形成される。 As shown in FIG. 2C, the pattern portion 12 is formed with a dark portion 14 serving as a shadow portion and a bright portion 13 serving as a portion exposed to light. The region forming the "dark" region of the first three-dimensional pattern forming section 20 shown in FIG. 2A and the region forming the "dark" region of the second three-dimensional pattern forming section 30 shown in FIG. 2B overlap, so that the region forming the "dark" region shown in FIG. The darkest part that is darker than the "dark" part of the first three-dimensional pattern forming part 20 and the "dark part" of the second three-dimensional pattern forming part 30 shown in FIG. 2B is formed in FIG. 2C.

また、図２Ａに示す第１立体模様形成部２０の「暗」を形成する領域と、図２Ｂに示す第２立体模様形成部３０の第２背景部３１や「明」を形成する領域が重なり合うことで、図２Ｃに暗部より明るい暗部が形成される。 Further, the area forming the "dark" area of the first three-dimensional pattern forming section 20 shown in FIG. 2A and the area forming the second background section 31 or "bright" of the second three-dimensional pattern forming section 30 shown in FIG. 2B overlap. As a result, a dark area that is brighter than the dark area is formed in FIG. 2C.

さらに、図２Ａに示す第１立体模様形成部２０の第１背景部２１や「明」を形成する領域と、図２Ｂに示す第２立体模様形成部３０の「暗」を形成する領域が重なり合うことで、図２Ｃに最暗部より明るい暗部が形成される。 Further, the first background portion 21 or the area forming the "bright" area of the first three-dimensional pattern forming section 20 shown in FIG. 2A overlaps with the area forming the "dark" area of the second three-dimensional pattern forming section 30 shown in FIG. 2B. As a result, a dark area that is brighter than the darkest area is formed in FIG. 2C.

さらに、図２Ａに示す第１立体模様形成部２０の「明」を形成する領域と、図２Ｂに示す第２立体模様形成部３０の「明」を形成する領域が重なり合うことで、図２Ｃに最明部が形成される。 Furthermore, the area forming the "light" of the first three-dimensional pattern forming section 20 shown in FIG. 2A and the area forming the "bright" of the second three-dimensional pattern forming section 30 shown in FIG. 2B overlap, so that the area shown in FIG. 2C The brightest part is formed.

また、図２Ａに示す第１立体模様形成部２０の「明」を形成する領域と、図２Ｂに示す第２立体模様形成部３０の第２背景部３１が重なり合うことで、図２Ｃに最明部より暗い明部が形成される。 Furthermore, the brightest region in FIG. 2C is caused by the overlapping of the "bright" region of the first three-dimensional pattern forming section 20 shown in FIG. 2A and the second background section 31 of the second three-dimensional pattern forming section 30 shown in FIG. 2B. A bright area that is darker than the other area is formed.

このように、本例の立体模様部１０は、暗部１４の最暗部と明部１３の最明部との明暗の差、すなわちコンストラスト差を大きくすることができる。さらに、暗部１４及び明部１３の明るさを複数段階に分けて表現することができる。これにより、模様部１２の明暗を細かく表現することができ、立体感が増した模様部１２を提供することができ、例えば、球体状の模様部を奥行き感があるように表現することができる。 In this way, the three-dimensional pattern section 10 of this example can increase the difference in brightness between the darkest part of the dark part 14 and the brightest part of the bright part 13, that is, the contrast difference. Furthermore, the brightness of the dark area 14 and the bright area 13 can be expressed in multiple stages. As a result, it is possible to express the brightness and darkness of the pattern portion 12 in detail, and it is possible to provide the pattern portion 12 with an increased three-dimensional effect.For example, it is possible to express a spherical pattern portion with a sense of depth. .

さらに、図２Ａに示す第１立体模様形成部２０と、図２Ｂに示す第２立体模様形成部３０を異なる色で形成することで、立体模様部１０における模様部１２の明暗をさらに細かく表現することができ、模様部１２の立体感を向上させることができる。なお、第１立体模様形成部２０と第２立体模様形成部３０は同じ色で形成してもよい。 Furthermore, by forming the first three-dimensional pattern forming part 20 shown in FIG. 2A and the second three-dimensional pattern forming part 30 shown in FIG. 2B in different colors, the brightness and darkness of the pattern part 12 in the three-dimensional pattern part 10 can be expressed more finely. Therefore, the three-dimensional effect of the pattern portion 12 can be improved. Note that the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30 may be formed in the same color.

また、本例の立体模様部１０を、第１版面の第１立体模様形成部２０と、第２版面の第２立体模様形成部３０の２つの版面に分割することで、印刷する際の版づまりを防止するという相乗効果も付与することが可能となる。 Furthermore, by dividing the three-dimensional pattern section 10 of this example into two printing plates, the first three-dimensional pattern forming section 20 on the first printing plate and the second three-dimensional pattern forming section 30 on the second printing plate, the printing plate It is also possible to provide a synergistic effect of preventing clogging.

なお、第１立体模様形成部２０及び第２立体模様形成部３０を形成する第１画線Ｌ２０及び第２画線Ｌ３０は、直線状に限定されるものではなく、例えば、波線状や破線等その他各種の画線が適用されるものである。なお、第２立体模様形成部３０の第２模様部３２を画線の太さで表現する例を説明したが、これに限定されるものではなく、第２模様部３２も第１模様部２２と同様に画線の位相差で表現してもよい。 Note that the first drawing line L20 and the second drawing line L30 forming the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30 are not limited to a linear shape, but may have a wavy line shape, a broken line, etc. Various other drawing lines may also be applied. Although an example has been described in which the second pattern part 32 of the second three-dimensional pattern forming part 30 is expressed by the thickness of the drawing line, the second pattern part 32 is also expressed by the thickness of the drawing line. Similarly, it may be expressed by the phase difference between the drawing lines.

さらに、上述した実施の形態例では、立体模様部１０を第１立体模様形成部２０と第２立体模様形成部３０の２版構成とする例を説明したが、立体模様部１０を３つ以上の立体模様形成部、すなわち３版以上の版面を重ね合わせて形成してもよい。版面を多くすることで、明暗をより細かく表現できるとともに最暗部と最明部のコントラスト差をより大きくすることができる。さらに、各版面を異なる色で形成してもよい。以上の結果、模様部１２の立体感をさらに向上させることができる。なお、立体模様部１０を３つ以上の立体模様形成部で形成する場合、各立体模様形成部を形成する画線の配列方向は、全て異なる方向にすることが好ましい。 Furthermore, in the embodiment described above, an example has been described in which the three-dimensional pattern section 10 has a two-dimensional configuration of the first three-dimensional pattern forming section 20 and the second three-dimensional pattern forming section 30, but three or more three-dimensional pattern sections 10 are provided. The three-dimensional pattern forming portion may be formed by overlapping three or more printing plates. By increasing the number of plates, it is possible to express brightness and darkness more precisely, and to increase the contrast difference between the darkest and brightest areas. Furthermore, each printing plate may be formed in a different color. As a result of the above, the three-dimensional effect of the pattern portion 12 can be further improved. Note that when the three-dimensional pattern section 10 is formed by three or more three-dimensional pattern forming sections, it is preferable that the drawing lines forming each three-dimensional pattern forming section are arranged in different directions.
