Description

本発明は転写方法及び転写治具に関し、詳しくは被印刷物の三次元形状の被転写面に軟質膜から塗料を転写するための転写方法及び転写治具に関するものである。   The present invention relates to a transfer method and a transfer jig, and more particularly to a transfer method and a transfer jig for transferring a paint from a soft film onto a three-dimensional transfer target surface of a printed material.

従来、曲面等を有する三次元形状の被印刷物の被転写面に絵付けする印刷方法の一つとして、特開平２−２３９９７２ 号公報（特許文献１）に示すようなパッド印刷がよく知られている。   Conventionally, pad printing as shown in JP-A-2-239972 (Patent Document 1) is well known as one of printing methods for painting on a transfer surface of a three-dimensional printed material having a curved surface or the like. Yes.

この印刷方法は、凹版を使用して転写を行うオフセット印刷の一種である。この印刷方法では、図５の（ａ）〜（ｆ）に示すように、（ａ）凹部３１を有する凹版印刷原版３０の表面に塗料３３を塗布し、凹版印刷原版３０の表面に塗られた塗料３３をヘラ状のブレード３２で取り除き、（ｂ）凹部３１のみに塗料３３を溜める。   This printing method is a kind of offset printing in which transfer is performed using an intaglio. In this printing method, as shown in (a) to (f) of FIG. 5, (a) the coating 33 is applied to the surface of the intaglio printing original plate 30 having the recesses 31 and applied to the surface of the intaglio printing original plate 30. The paint 33 is removed with a spatula blade 32, and (b) the paint 33 is stored only in the recess 31.

その後、（ｃ）曲面を有する軟質パッド３４を凹版印刷原版３０の表面のほぼ全体に押し付けてから、（ｄ）軟質パッド３４を凹版印刷原版３０の表面から剥がし、軟質パッド３４の表面に塗料３３を中間転写する。   Thereafter, (c) the soft pad 34 having a curved surface is pressed against almost the entire surface of the intaglio printing original plate 30, and (d) the soft pad 34 is peeled off from the surface of the intaglio printing original plate 30, and the coating 33 is applied to the surface of the soft pad 34. Intermediate transfer.

その後、（ｅ）塗料３３が中間転写された軟質パッド３４を被印刷物３５の被転写面に押し付けてから、（ｆ）軟質パッド３４を被印刷物３５から剥がし、被印刷物３５の被転写面に塗料３３を転写する。   Thereafter, (e) the soft pad 34 onto which the coating material 33 has been intermediately transferred is pressed against the transfer surface of the substrate 35, and (f) the soft pad 34 is peeled off from the substrate 35, and the coating surface of the substrate 35 is coated with the coating material. 33 is transferred.

以上の動作の中で、塗料３３は空気に露出している部分から乾燥し始め、塗料３３の粘性が上がる。このため、凹版印刷原版３０から軟質パッド３４に、次に軟質パッド３４から被印刷物３５へと、塗料３３が転写される。
特開平２−２３９９７２号公報 During the above operation, the paint 33 starts to dry from the portion exposed to the air, and the viscosity of the paint 33 increases. For this reason, the coating material 33 is transferred from the intaglio printing original plate 30 to the soft pad 34 and then from the soft pad 34 to the substrate 35.
JP-A-2-239972

しかしながら、図５に示した従来のパッド印刷においては、凹版印刷原版３０から一旦軟質パッド３４に中間転写した塗料３３を被印刷物３５の被転写面に転写するため、中間転写を行う分、工程が長くかかり、印刷コストが高くなっていた。   However, in the conventional pad printing shown in FIG. 5, the coating 33 once transferred from the intaglio printing original plate 30 to the soft pad 34 is transferred to the transfer surface of the printing material 35. It took a long time and the printing cost was high.

また、軟質パッド３４については、被印刷物３５の被転写面への転写に適した形状とする必要があるため、被転写面の形状毎に異なる形状の軟質パッド３４が必要になる。凹版印刷原版３０についても、絵付け模様に応じて、凹部３１の形状や配置を変えなければならない。このため、多品種の被印刷物３５に印刷する場合、凹版印刷原版３０と軟質パッド３４の準備や取り替えに多大な時間を要し、印刷コストが高くなっていた。   Further, the soft pad 34 needs to have a shape suitable for the transfer of the printing material 35 to the transfer surface, and therefore a soft pad 34 having a different shape is required for each shape of the transfer surface. Also for the intaglio printing original plate 30, the shape and arrangement of the recesses 31 must be changed according to the painting pattern. For this reason, when printing on various types of substrate 35, it takes a lot of time to prepare and replace the intaglio printing original plate 30 and the soft pad 34, and the printing cost is high.

さらに、被印刷物３５の被転写面が複雑な形状であり、突起や窪みを有しているような場合には、軟質パッド３４を被印刷物３５の被転写面に押し付ける際に、軟質パッド３４が被転写面の突起に引っかかって不均一に引き延ばされたり、被転写面の窪みの形状に変形追随しきれなくなることによって、印刷ムラが発生したり、絵柄を正確に印刷できないなどの印刷品質の低下を招くという問題もあった。   Furthermore, when the transfer surface of the substrate 35 has a complicated shape and has protrusions or depressions, the soft pad 34 is pressed when the soft pad 34 is pressed against the transfer surface of the substrate 35. Print quality such as uneven printing due to catching on protrusions on the transfer surface or non-uniform extension of the shape of the depression on the transfer surface, resulting in print irregularities and inability to print the pattern accurately There was also the problem of inviting a decline in

本発明は上記課題に鑑みてなされたものであり、中間転写工程を不要とするとともに、被印刷物毎の凹版印刷原版と軟質パッドの取り替えを不要とすることで、作業時間の短縮と印刷コストの低減を図ることができ、さらに、被印刷物が複雑な形状の場合であっても印刷品質の低下を招くことのない転写方法及び転写治具を提供することを目的とする。   The present invention has been made in view of the above problems, and eliminates the need for an intermediate transfer step and eliminates the need to replace the intaglio printing original plate and the soft pad for each substrate, thereby reducing work time and printing costs. It is another object of the present invention to provide a transfer method and a transfer jig that can be reduced, and that do not cause a decrease in print quality even when the substrate has a complicated shape.

以下、上記課題を解決するのに適した各手段につき、必要に応じて作用効果等を付記しつつ説明する。   Hereinafter, each means suitable for solving the above-described problems will be described with additional effects and the like as necessary.

本発明の転写方法は、凹部、該凹部の内面に形成された三次元形状の型面、及び該型面に開口する貫通孔を有する型と、平板状の軟質膜とを用いて、該型面と相似形状又は略相似形状の被転写面を有する被印刷物の該被転写面に該軟質膜から塗料を転写する転写方法であって、前記凹部を塞ぐように前記軟質膜を前記型に配置する軟質膜配置工程と、前記軟質膜配置工程の前工程又は後工程として、前記軟質膜に塗料を印刷する軟質膜印刷工程と、前記貫通孔から前記凹部内を真空引きして、前記軟質膜を前記型面の少なくとも一部に接触する位置まで変形させる軟質膜変形工程と、変形した前記軟質膜に前記被印刷物の前記被転写面を押し付けて、該軟質膜から該被転写面に前記塗料を転写する被印刷物押付工程と、前記塗料が転写された前記被印刷物を前記軟質膜から剥がす被印刷物取出工程と、を備えることを特徴とする。   The transfer method of the present invention uses a mold having a recess, a three-dimensional mold surface formed on the inner surface of the recess, a through-hole opening in the mold surface, and a flat soft film. A transfer method for transferring a coating material from a soft film to a transfer surface of a printed material having a transfer surface having a shape similar to or substantially similar to a surface, wherein the soft film is disposed in the mold so as to close the concave portion A soft film placement step, a soft film printing step for printing a paint on the soft film as a pre-process or a post-process of the soft film placement step, and evacuating the recess from the through-hole, A soft film deforming step for deforming the film to a position in contact with at least a part of the mold surface, pressing the transferred surface of the printed material against the deformed soft film, and applying the coating material from the soft film to the transferred surface The substrate pressing process to transfer the paint and the paint was transferred Serial, characterized in that it comprises, and the substrate removal step of peeling the printing material from the soft membrane.

このような構成によれば、軟質膜（軟質パッド）が従来のパッド印刷で用いられる立体の軟質パッドとは異なり平板状であるため、プリンタ等の印刷機により軟質膜に直接塗料を印刷することができる。これにより、従来のパッド印刷で必要としていた軟質パッドへの塗料の中間転写工程が不要となり、転写工程が簡素化されるため、作業時間の短縮と印刷コストの低減を図ることができる。なお、軟質膜への塗料の印刷は、軟質膜配置工程の前工程として行ってもよいし、後工程として行ってもよい。   According to such a configuration, the soft film (soft pad) has a flat plate shape, unlike the three-dimensional soft pad used in conventional pad printing, and therefore the paint is directly printed on the soft film by a printer such as a printer. Can do. As a result, the intermediate transfer process of the paint to the soft pad required in the conventional pad printing becomes unnecessary, and the transfer process is simplified, so that the working time can be shortened and the printing cost can be reduced. In addition, printing of the coating material to a soft film may be performed as a pre-process of a soft film arrangement | positioning process, and may be performed as a post process.

また、従来のパッド印刷で多品種の被印刷物に印刷する場合には、被印刷物の絵付け模様に応じて凹版印刷原版の制作が必要となっていたが、本発明の構成によれば、プリンタ等の印刷機により軟質膜に直接塗料を印刷することができるため、凹版印刷原版の制作は不要であり、多品種印刷に適している。また、被印刷物毎の凹版印刷原版の準備や取り替えが不要であるため、作業時間の短縮と印刷コストの低減を図ることができる。   In addition, when printing on various types of printed materials by conventional pad printing, it is necessary to produce an intaglio printing original plate according to the painting pattern of the printed material. According to the configuration of the present invention, the printer Since the paint can be directly printed on the soft film by a printing machine such as a printing press, it is not necessary to produce an intaglio printing original plate and is suitable for multi-product printing. In addition, since it is not necessary to prepare or replace the intaglio printing original plate for each substrate, it is possible to shorten the work time and the printing cost.

また、凹部の内面に形成された型を取り替えることによって、真空引き後の軟質膜の変形形状を制御することができるため、軟質膜を取り替えることなく、容易に被印刷物の被転写面の形状に対応した転写治具に組み替えることができる。したがって、本発明の転写方法は多品種印刷に適している。   In addition, by changing the mold formed on the inner surface of the recess, the deformed shape of the soft film after evacuation can be controlled, so that the shape of the transfer surface of the printed material can be easily changed without replacing the soft film. It can be rearranged to the corresponding transfer jig. Therefore, the transfer method of the present invention is suitable for multi-product printing.

また、本発明の転写方法は、被印刷物の被転写面を軟質膜に押し付ける前に、軟質膜を被印刷物の被転写面に近い形状に変形させておくことによって、被転写面を軟質膜に押し付ける際の軟質膜の変形を極力小さく抑えることができる。したがって、被印刷物の被転写面が複雑な形状の場合であっても、軟質膜が不均一に引き延ばされることがなく、被転写面と軟質膜とを十分に密着させることができる。これにより、印刷ムラや絵柄の変形を発生させることなく、良好な印刷品質を確保することができる。   Further, the transfer method of the present invention transforms the transfer surface into a soft film by deforming the soft film into a shape close to the transfer surface of the print before pressing the transfer surface of the print onto the soft film. The deformation of the soft film during pressing can be suppressed as much as possible. Therefore, even when the transfer surface of the printing material has a complicated shape, the soft film is not stretched unevenly, and the transfer surface and the soft film can be sufficiently adhered to each other. As a result, it is possible to ensure good print quality without causing printing unevenness or pattern deformation.

本発明の転写方法は、好適な態様において、前記軟質膜印刷工程において、前記軟質膜への塗料の印刷をプリンタにより行うことを特徴とする。   In a preferred aspect, the transfer method of the present invention is characterized in that, in the soft film printing step, a paint is printed on the soft film by a printer.

本発明に係る軟質膜は、従来のパッド印刷で用いられる立体の軟質パッドとは異なり平板状であるため、軟質膜への塗料の印刷方法として、凸版印刷、凹版印刷、スクリーン印刷等の様々な印刷方法を採用することが可能であるが、コンピュータからの指令に基づいて印刷を行うプリンタを用いると最も作業効率がよい。   Unlike the three-dimensional soft pad used in conventional pad printing, the soft film according to the present invention has a flat plate shape. Therefore, various methods such as letterpress printing, intaglio printing, and screen printing can be used as a method for printing a paint on the soft film. Although a printing method can be adopted, working efficiency is best when a printer that performs printing based on a command from a computer is used.

本発明の転写方法は、好適な態様において、前記被印刷物押付工程において、前記凹部内を前記貫通孔から大気に開放した状態で、前記被印刷物の前記被転写面を前記軟質膜に押し付けて、該軟質膜と前記型面とを密着させることを特徴とする。   In a preferred aspect, the transfer method of the present invention, in a preferred embodiment, in the printing material pressing step, in the state where the inside of the recess is open to the atmosphere from the through hole, the printing surface of the printing material is pressed against the soft film, The soft film and the mold surface are brought into close contact with each other.

凹部内の空気を貫通孔を通して大気に開放した状態で、被印刷物の被転写面を軟質膜に押し付けることによって、被印刷物の被転写面と軟質膜との密着性を確実にした後に、軟質膜と型の型面とを密着させることができる。この転写方法によれば、仮に型の成形精度が若干悪く、型面に多少の成形不良凹部が存在しているような場合であっても、軟質膜を型面に押し付ける前に、被印刷物の被転写面と軟質膜とを完全に密着させ、その後、被転写面を軟質膜に押し付ける押付圧によって、凹部内の空気を外部に排出しながら軟質膜と型面との密着性を高めることができる。これにより、軟質膜を型面の成形不良凹部に沿って変形させることなく、成形不良凹部の存在に左右されずに、良好な印刷品質を確保することができる。   After the air in the recess is released to the atmosphere through the through-hole, the soft film is secured after the transfer surface of the print medium is pressed against the soft film to ensure the adhesion between the transfer surface of the print medium and the soft film. And the mold surface of the mold can be brought into close contact with each other. According to this transfer method, even if the molding accuracy of the mold is somewhat poor and there are some molding defects on the mold surface, before pressing the soft film against the mold surface, The surface to be transferred and the soft film are completely brought into close contact with each other, and then the pressure between the surface to be transferred and the soft film is pressed to increase the adhesion between the soft film and the mold surface while discharging the air in the recesses to the outside. it can. Thereby, it is possible to ensure a good print quality without being influenced by the presence of the defective molding recess without deforming the soft film along the molding defective recess on the mold surface.

本発明の転写方法は、好適な態様において、前記被印刷物取出工程において、前記貫通孔から前記凹部に向かって空気を供給しながら、前記塗料が転写された前記被印刷物を前記軟質膜から剥がすことを特徴とする。   In a preferred aspect, in the transfer method of the present invention, in the printing material take-out step, the printing material to which the coating material has been transferred is peeled off from the soft film while supplying air from the through hole toward the concave portion. It is characterized by.

被印刷物の被転写面と軟質膜とは密着しているため、被印刷物を軟質膜から剥がす際には、被印刷物の被転写面と軟質膜との接触面に負圧が発生する。この状態で、無理に被印刷物を剥がすと、絵柄の変形等の印刷品質の低下を招く場合がある。本発明の転写方法は、貫通孔から凹部に向かって空気を供給することにより軟質膜を膨らませながら、被印刷物を軟質膜から剥がす構成であるため、接触面に負圧を発生させることなく、被印刷物を軟質膜から容易に剥がすことができる。   Since the transfer surface of the printing material and the soft film are in close contact with each other, a negative pressure is generated on the contact surface between the transfer surface of the printing material and the soft film when the printing material is peeled off from the soft film. In this state, if the printed material is forcibly peeled off, the print quality may be deteriorated such as deformation of the pattern. The transfer method of the present invention is configured to peel off the printed material from the soft film while inflating the soft film by supplying air from the through-hole toward the concave portion, so that a negative pressure is not generated on the contact surface. The printed material can be easily peeled off from the soft film.

本発明の転写方法は、好適な態様において、さらに、前記被印刷物押付工程の後工程として、前記被印刷物の前記被転写面を前記軟質膜に押し付けた状態を保ったままで、前記貫通孔から前記凹部に向かって空気を供給して該軟質膜を該被転写面に押し付ける軟質膜押付工程を備えることを特徴とする。   In a preferred embodiment, the transfer method according to the present invention may further include, as a subsequent step of the printing object pressing step, from the through hole while maintaining the state where the transfer surface of the printing object is pressed against the soft film. A soft film pressing step is provided, in which air is supplied toward the recess to press the soft film against the transfer surface.

被印刷物押付工程において、被印刷物の被転写面と軟質膜との接触面の圧力は、型面の成形精度や軟質膜変形工程における軟質膜の変形具合等に左右されて、被転写面の全面にわたって均一な圧力とはならない場合がある。このような場合であっても、被印刷物押付工程の後工程として軟質膜押付工程を実施すれば、貫通孔から凹部に向かって供給された空気によって軟質膜が膨らみ、軟質膜が被印刷物の被転写面に押し付けられる圧力をより均一な状態に近づけることができる。これにより、被印刷物の被転写面と軟質膜との密着性はより確実となり、良好な印刷品質を確保することができる。   In the substrate pressing process, the pressure on the contact surface of the substrate to be transferred and the soft film depends on the molding accuracy of the mold surface and the degree of deformation of the soft film in the soft film deformation process. The pressure may not be uniform over the entire area. Even in such a case, if the soft film pressing process is performed as a subsequent process of the printed material pressing process, the soft film swells due to the air supplied from the through hole toward the concave portion, and the soft film is applied to the printed material. The pressure pressed against the transfer surface can be brought closer to a more uniform state. Thereby, the adhesiveness of the to-be-transferred surface of a to-be-printed material and a soft film becomes more reliable, and favorable printing quality can be ensured.

本発明の転写治具は、軟質膜に印刷された塗料を、被印刷物の三次元形状の被転写面に転写する転写治具であって、凹部、該凹部の内面に形成された前記被転写面と相似形状又は略相似形状の型面、及び該型面に開口する貫通孔を有する型と、塗料が印刷される平板状の軟質膜と、前記軟質膜で塞がれた前記凹部内を前記貫通孔から真空引きすることにより、該軟質膜を前記型面の少なくとも一部に接触する位置まで変形させる真空引き手段と、を備えることを特徴とする。   The transfer jig of the present invention is a transfer jig for transferring a paint printed on a soft film to a three-dimensional transfer target surface of a printing material, the recess being formed on the inner surface of the recess. A mold surface having a shape similar to or substantially similar to the surface, a mold having a through-hole opening in the mold surface, a flat soft film on which a paint is printed, and the inside of the recess closed by the soft film And vacuuming means for deforming the soft film to a position in contact with at least a part of the mold surface by vacuuming from the through hole.

このような構成によれば、軟質膜が従来のパッド印刷で用いられる立体の軟質パッドとは異なり平板状であるため、プリンタ等の印刷機により軟質膜に直接塗料を印刷することができる。これにより、従来のパッド印刷で必要としていた軟質パッドへの塗料の中間転写工程が不要となり、転写工程が簡素化されるため、作業時間の短縮と印刷コストの低減を図ることができる。   According to such a configuration, unlike the three-dimensional soft pad used in conventional pad printing, the soft film has a flat plate shape, so that the paint can be directly printed on the soft film by a printer such as a printer. As a result, the intermediate transfer process of the paint to the soft pad required in the conventional pad printing becomes unnecessary, and the transfer process is simplified, so that the working time can be shortened and the printing cost can be reduced.

また、従来のパッド印刷で多品種の被印刷物に印刷する場合には、被印刷物の絵付け模様に応じて凹版印刷原版の制作が必要となっていたが、本発明の構成によれば、プリンタ等の印刷機により軟質膜に直接塗料を印刷することができるため、凹版印刷原版の制作は不要であり、多品種印刷に適している。また、被印刷物毎の凹版印刷原版の準備や取り替えが不要であるため、作業時間の短縮と印刷コストの低減を図ることができる。   In addition, when printing on various types of printed materials by conventional pad printing, it is necessary to produce an intaglio printing original plate according to the painting pattern of the printed material. According to the configuration of the present invention, the printer Since the paint can be directly printed on the soft film by a printing machine such as a printing press, it is not necessary to produce an intaglio printing original plate and is suitable for multi-product printing. In addition, since it is not necessary to prepare or replace the intaglio printing original plate for each substrate, it is possible to shorten the work time and the printing cost.

また、凹部の内面に形成された型を取り替えることによって、真空引き後の軟質膜の変形形状を制御することができるため、軟質膜を取り替えることなく、容易に被印刷物の被転写面の形状に対応した転写治具に組み替えることができる。したがって、本発明の転写治具は多品種印刷に適している。   In addition, by changing the mold formed on the inner surface of the recess, the deformed shape of the soft film after evacuation can be controlled, so that the shape of the transfer surface of the printed material can be easily changed without replacing the soft film. It can be rearranged to the corresponding transfer jig. Therefore, the transfer jig of the present invention is suitable for multi-product printing.

また、本発明の転写治具は、被印刷物の被転写面を軟質膜に押し付ける前に、軟質膜を被印刷物の被転写面に近い形状に変形させておくことによって、被転写面を軟質膜に押し付ける際の軟質膜の変形を極力小さく抑えることができる。したがって、被印刷物の被転写面が複雑な形状の場合であっても、軟質膜が不均一に引き延ばされることがなく、被転写面と軟質膜とを十分に密着させることができる。これにより、印刷ムラや絵柄の変形を発生させることなく、良好な印刷品質を確保することができる。   In addition, the transfer jig of the present invention deforms the soft film into a shape close to the transfer surface of the printing material before pressing the transfer surface of the printing material against the soft film. The deformation of the soft film when it is pressed against can be suppressed as much as possible. Therefore, even when the transfer surface of the printing material has a complicated shape, the soft film is not stretched unevenly, and the transfer surface and the soft film can be sufficiently adhered to each other. As a result, it is possible to ensure good print quality without causing printing unevenness or pattern deformation.

本発明の転写治具は、好適な態様において、さらに、前記貫通孔から前記凹部に向かって空気を供給する空気供給手段を備えることを特徴とする。   In a preferred aspect, the transfer jig of the present invention further includes air supply means for supplying air from the through hole toward the recess.

このような構成によれば、転写治具は真空引き手段に加えて空気供給手段も備えているため、凹部内の空気量を調整することで、軟質膜の変形具合を制御することができる。   According to such a configuration, since the transfer jig also includes an air supply unit in addition to the vacuuming unit, the degree of deformation of the soft film can be controlled by adjusting the amount of air in the recess.

本発明の転写治具は、好適な態様において、前記軟質膜の塗料が印刷される被印刷面に、該塗料の流動を抑制する微細凹凸が形成されていることを特徴とする。   In a preferred embodiment, the transfer jig of the present invention is characterized in that fine unevenness that suppresses the flow of the paint is formed on a printing surface on which the paint of the soft film is printed.

微細凹凸が抵抗となることにより塗料の側方への流動が抑制されるため、軟質膜に微細パターンの絵柄を印刷した場合であっても、この絵柄が崩れることなく保持され、印刷品質の低下を招くことなく、微細パターンの転写が可能となる。   Since the flow of the paint to the side is suppressed due to the resistance of the fine irregularities, even when a pattern with a fine pattern is printed on a soft film, this pattern is maintained without breaking down and the print quality deteriorates It is possible to transfer a fine pattern without incurring.

以下、本発明の転写治具を具体化した実施形態について図面を参照しつつ具体的に説明する。   Hereinafter, embodiments of the transfer jig according to the present invention will be described in detail with reference to the drawings.

本実施形態の転写治具１は、上部に開口部を有する有底筒型の容器２と、容器２の開口部を密閉するとともに、被印刷物１２の被転写面１２ａに転写する塗料１１が印刷された平板状の軟質膜３と、容器２内に配置されるとともに、軟質膜３側に被印刷物１２の被転写面１２ａと相似形状又は略相似形状からなる型面５を有する型４と、軟質膜３で密閉された容器２内の空気を真空引きする真空引き手段、および、容器２内へ空気を供給する空気供給手段としてのポンプＰとにより構成されている。   The transfer jig 1 of this embodiment seals the bottomed cylindrical container 2 having an opening at the top, and the opening of the container 2, and prints the paint 11 to be transferred to the transfer surface 12 a of the substrate 12. A flat plate-like soft film 3 and a mold 4 which is disposed in the container 2 and has a mold surface 5 having a shape similar to or substantially similar to the transfer surface 12a of the printed material 12 on the soft film 3 side; A vacuum evacuation means for evacuating the air in the container 2 sealed with the soft film 3 and a pump P as an air supply means for supplying air into the container 2 are configured.

容器２は、容器２内の空気を真空引きする際の負圧に対して変形しない程度の剛性を有する材料として、例えば、アルミニウム板からなり、容器２内には型４を配置して固定することが可能な型固定部材（図示せず）を有している。   The container 2 is made of, for example, an aluminum plate as a material that does not deform with respect to the negative pressure when the air in the container 2 is evacuated, and the mold 4 is disposed and fixed in the container 2. And a mold fixing member (not shown).

軟質膜３は、容器２内の空気を真空引きする前には、平板状に自立可能な剛性を有するとともに、容器２内の空気を真空引きする際の負圧に対して柔軟に変形する柔軟性を有する材料として、例えば、厚さｔ＝３〜５ｍｍのシリコンからなる。また、軟質膜３の塗料１１が印刷される被印刷面３ａは、印刷品質を確保するために鏡面仕上が施されている。   The soft film 3 has a rigidity capable of self-supporting in a flat plate shape before the air in the container 2 is evacuated, and is flexible so as to be flexibly deformed against a negative pressure when the air in the container 2 is evacuated. For example, the material having the property is made of silicon having a thickness t = 3 to 5 mm. The printed surface 3a on which the coating material 11 of the soft film 3 is printed has a mirror finish to ensure print quality.

型４は、被印刷物１２の被転写面１２ａと相似形状又は略相似形状の型面５を有しており、この型面５を軟質膜３側（容器２の開口部側）に向けて容器２内に配置されている。この型面５の形状は、図１（ｃ）における要部Ａを拡大して示している図２のとおり、軟質膜３の厚さｔに相当する分だけ被印刷物１２の被転写面１２ａから拡大（オフセット）された形状となっている。   The mold 4 has a mold surface 5 having a shape similar to or substantially similar to the transfer surface 12a of the substrate 12, and the container 5 is directed toward the soft film 3 (opening side of the container 2). 2 is arranged. The shape of the mold surface 5 is as follows from the transfer surface 12a of the substrate 12 by the amount corresponding to the thickness t of the soft film 3, as shown in FIG. It has an enlarged (offset) shape.

なお、型面５は被印刷物１２の被転写面１２ａと相似形状となっていることが望ましいが、ある程度相似な形状、すなわち略相似形状であれば、後述する被印刷物押付工程において、軟質膜３と被転写面１２ａとを十分に密着させることができるため、良好な印刷品質を確保する上での支障はない。   The mold surface 5 is preferably similar in shape to the transfer surface 12a of the substrate 12; however, if it is somewhat similar in shape, that is, substantially similar, the soft film 3 is used in the substrate pressing process described later. And the transfer surface 12a can be sufficiently adhered to each other, so that there is no problem in securing good print quality.

型４には、複数の貫通孔６が形成されており、貫通孔６の一端は型面５に、他端は型４の型面５と反対側の面に開口している。これにより、容器２の開口部を軟質膜３で密閉した状態において形成される型下容器内空間７と型上容器内空間８とが貫通孔６によって連通している。   A plurality of through holes 6 are formed in the mold 4, and one end of the through hole 6 opens on the mold surface 5, and the other end opens on a surface of the mold 4 opposite to the mold surface 5. As a result, the lower container inner space 7 and the upper container inner space 8 formed in a state where the opening of the container 2 is sealed with the soft film 3 communicate with each other through the through hole 6.

なお、複数の貫通孔６の数および配置は、被印刷物１２の被転写面１２ａの面積や形状に応じて適切に配置する必要がある。例えば、後述する軟質膜変形工程において、軟質膜３を型面５に沿って正確に変形させるためには、型面５の全面にわたって多数の貫通孔６が均一に分散した配置とすることが望ましく、少なくとも、型面５の最も窪んだ部分には貫通孔６を配置しておくことが望ましい。   Note that the number and arrangement of the plurality of through holes 6 need to be appropriately arranged according to the area and shape of the transferred surface 12a of the printing material 12. For example, in order to accurately deform the soft film 3 along the mold surface 5 in the soft film deformation process described later, it is desirable that the multiple through holes 6 be uniformly distributed over the entire mold surface 5. It is desirable that the through hole 6 be disposed at least in the most depressed portion of the mold surface 5.

容器２の側壁には、型下容器内空間７と容器２の外部とを連通する貫通孔９が形成されており、貫通孔９とポンプＰが配管１０によって接続されている。配管１０の脱着を容易にするためには貫通孔９と配管１０をカプラで接続するとよい。   A through-hole 9 is formed in the side wall of the container 2 so as to communicate the lower mold inner space 7 and the outside of the container 2, and the through-hole 9 and the pump P are connected by a pipe 10. In order to facilitate the attachment / detachment of the pipe 10, the through hole 9 and the pipe 10 may be connected by a coupler.

本実施形態に係る転写方法を図１（ａ）〜（ｄ）および図３により説明する。   The transfer method according to this embodiment will be described with reference to FIGS. 1 (a) to 1 (d) and FIG.

図１（ａ）は軟質膜配置工程後の軟質膜印刷工程を示し、軟質膜配置工程において、容器２の開口部を軟質膜３で密閉した後に、軟質膜印刷工程において、被印刷物１２の被転写面１２ａに転写する塗料１１が軟質膜３に印刷された状態である。軟質膜３への塗料１１の印刷は、図３に示すとおり、コンピュータからの指令に基づいて印刷を行うインクジェットプリンタ１３を用いると作業効率がよい。   FIG. 1A shows a soft film printing process after the soft film arranging process. In the soft film arranging process, after the opening of the container 2 is sealed with the soft film 3, the soft film printing process is performed in the soft film printing process. The paint 11 to be transferred to the transfer surface 12a is printed on the soft film 3. As shown in FIG. 3, the printing of the coating material 11 on the soft film 3 is efficient when an ink jet printer 13 that performs printing based on a command from a computer is used.

このインクジェットプリンタ１３の構造は、用紙印刷を行う市販のインクジェットプリンタと同様であるが、用紙の代わりに転写治具１が設置される点で異なる。   The structure of the ink jet printer 13 is the same as that of a commercially available ink jet printer that performs paper printing, but differs in that the transfer jig 1 is installed instead of paper.

インクジェットプリンタ１３は、塗料１１を吐出するインクジェットヘッド１４、転写治具１が設置される転写治具設置台１５を備えており、転写治具設置台１５には、転写治具送り機構１６と高さ調整機構１７が備わっている。   The ink jet printer 13 includes an ink jet head 14 that discharges the coating material 11 and a transfer jig installation base 15 on which the transfer jig 1 is installed. A height adjusting mechanism 17 is provided.

軟質膜３への塗料１１の印刷は、容器２への軟質膜３と型４の取り付けが完了し、配管１０が接続されていない状態の転写治具１をインクジェットプリンタ１３の転写治具設置台１５に設置する。続いて、インクジェットヘッド１４と軟質膜３とが所定の間隔になるまで、高さ調整機構１７で転写治具設置台１５の高さを調整する。   Printing of the coating material 11 on the soft film 3 is performed by replacing the transfer jig 1 in a state where the soft film 3 and the mold 4 are attached to the container 2 and the pipe 10 is not connected with the transfer jig on the ink jet printer 13. 15 is installed. Subsequently, the height of the transfer jig mounting base 15 is adjusted by the height adjusting mechanism 17 until the ink jet head 14 and the soft film 3 become a predetermined distance.

続いて、インクジェットプリンタ１３にコンピュータから指令を送り、ガイドに沿ってインクジェットヘッド１４を往復動しながら、インクジェットヘッド１４から軟質膜３に向けて塗料１１を吐出するとともに、これに同調して転写治具送り機構１６で転写治具１を送ることで軟質膜３に所定の絵柄の印刷を行う。   Subsequently, a command is sent from the computer to the ink jet printer 13, and the ink jet head 14 is reciprocated along the guide while the paint 11 is discharged from the ink jet head 14 toward the soft film 3. A predetermined pattern is printed on the soft film 3 by feeding the transfer jig 1 with the tool feeding mechanism 16.

軟質膜３への印刷が終了した後、転写治具１にポンプＰを接続することで、図１（ａ）に示す状態となる。   After the printing on the soft film 3 is completed, the pump P is connected to the transfer jig 1 so that the state shown in FIG.

このように、本実施形態の軟質膜３は、従来のパッド印刷で用いられる立体の軟質パッドとは異なり平板状であるため、インクジェットプリンタ１３を用いて軟質膜３の被印刷面３ａに直接塗料１１を印刷することができる。これにより、従来のパッド印刷で必要としていた軟質パッドへの塗料の中間転写工程が不要となり、転写工程が簡素化されるため、作業時間の短縮と印刷コストの低減を図ることができる。   As described above, the soft film 3 of the present embodiment has a flat plate shape unlike the three-dimensional soft pad used in the conventional pad printing, and thus the ink-jet printer 13 is used to directly paint the printed surface 3a of the soft film 3. 11 can be printed. As a result, the intermediate transfer process of the paint to the soft pad required in the conventional pad printing becomes unnecessary, and the transfer process is simplified, so that the working time can be shortened and the printing cost can be reduced.

また、従来のパッド印刷で多品種の被印刷物に印刷する場合には、被印刷物の絵付け模様に応じて凹版印刷原版の制作が必要となっていたが、本実施形態では、インクジェットプリンタ１３により軟質膜３に直接塗料１１を印刷することができるため、凹版印刷原版の制作は不要であり、多品種印刷に適している。また、被印刷物毎の凹版印刷原版の準備や取り替えが不要であるため、作業時間の短縮と印刷コストの低減を図ることができる。   In addition, when printing on various types of printed materials by conventional pad printing, it is necessary to produce an intaglio printing original plate according to the painting pattern of the printed material. In the present embodiment, the inkjet printer 13 is used. Since the paint 11 can be printed directly on the soft film 3, it is not necessary to produce an intaglio printing original plate, which is suitable for multi-product printing. In addition, since it is not necessary to prepare or replace the intaglio printing original plate for each substrate, it is possible to shorten the work time and the printing cost.

図１（ｂ）は軟質膜印刷工程に続いて、軟質膜３を型４の型面５に接触する位置まで変形させる軟質膜変形工程を示している。ポンプＰによって容器２内の空気を真空引きすると、軟質膜３が下方に湾曲しながら変形することにより、型上容器内空間８の空気が貫通孔６を通して排出され、軟質膜３が型面５の全面に完全に密着する。   FIG. 1B shows a soft film deformation process in which the soft film 3 is deformed to a position in contact with the mold surface 5 of the mold 4 following the soft film printing process. When the air in the container 2 is evacuated by the pump P, the soft film 3 is deformed while being bent downward, whereby the air in the mold upper container inner space 8 is discharged through the through hole 6, and the soft film 3 is removed from the mold surface 5. Adheres completely to the entire surface.

ここに、被印刷物１２の被転写面１２ａの形状が異なる多品種の被印刷物１２に印刷を行う場合には、容器２内に配置されている型４を取り替えることによって、真空引き後の軟質膜３の変形形状を制御することができるため、軟質膜３を取り替えることなく、容易に被印刷物１２の被転写面１２ａの形状に対応した転写治具１に組み替えることができる。したがって、本実施形態の転写方法は多品種印刷に容易に対応することができる。   Here, in the case where printing is performed on various types of printed materials 12 having different shapes of the transferred surface 12a of the printed material 12, the soft film after evacuation is obtained by replacing the mold 4 disposed in the container 2. 3 can be controlled, so that the soft film 3 can be easily replaced with the transfer jig 1 corresponding to the shape of the transfer surface 12a of the substrate 12 without replacing the soft film 3. Therefore, the transfer method of this embodiment can easily cope with multi-product printing.

図１（ｃ）は軟質膜変形工程に続いて、変形した軟質膜３に被印刷物１２の被転写面１２ａを押し付けることによって、塗料１１を被印刷物１２の被転写面１２ａに転写する被印刷物押付工程を示している。必要に応じて、被印刷物１２の被転写面１２ａを軟質膜３に押し付けた後、この状態を保ったままで、容器２内へポンプＰにより空気を供給すれば、貫通孔６を通して型上容器内空間８に空気が供給されることにより軟質膜３が膨らみ、軟質膜３が被印刷物１２の被転写面１２ａに押し付けられる圧力をより均一な状態に近づけることが可能である。   FIG. 1 (c) shows a printing object pressing that transfers the coating material 11 to the transferred surface 12 a of the printed material 12 by pressing the transferred surface 12 a of the printed material 12 against the deformed soft film 3 following the soft film deformation step. The process is shown. If necessary, after the transfer surface 12a of the substrate 12 is pressed against the soft film 3, if the air is supplied into the container 2 by the pump P while maintaining this state, the inside of the mold upper container is passed through the through hole 6. When the air is supplied to the space 8, the soft film 3 swells, and the pressure with which the soft film 3 is pressed against the transfer surface 12 a of the substrate 12 can be made closer to a more uniform state.

本実施形態においては、型面５の全面にわたって多数の貫通孔６が配置されているため、上述の圧力をより均一な状態に近づける効果が高く、これにより、被印刷物１２の被転写面１２ａと軟質膜３との密着性はより確実となり、良好な印刷品質を確保することができる。   In the present embodiment, since a large number of through-holes 6 are arranged over the entire surface of the mold surface 5, the effect of bringing the above-mentioned pressure closer to a more uniform state is high. Adhesion with the soft film 3 becomes more reliable, and good print quality can be ensured.

なお、本実施形態の転写方法は、被印刷物１２の被転写面１２ａを軟質膜３に押し付ける前に、軟質膜３を被印刷物１２の被転写面１２ａに近い形状に変形させておく転写方法であるため、被転写面１２ａを軟質膜３に押し付ける際の軟質膜３の変形を極力小さく抑えることができる。したがって、被印刷物１２の被転写面１２ａが複雑な形状の場合であっても、軟質膜３が不均一に引き延ばされることがなく、被転写面１２ａと軟質膜３とを十分に密着させることができる。これにより、印刷ムラや絵柄の変形を発生させることなく、良好な印刷品質を確保することができる。   The transfer method according to the present embodiment is a transfer method in which the soft film 3 is deformed into a shape close to the transfer surface 12a of the substrate 12 before the transfer surface 12a of the substrate 12 is pressed against the soft film 3. Therefore, the deformation of the soft film 3 when the transfer surface 12a is pressed against the soft film 3 can be minimized. Therefore, even if the transfer surface 12a of the substrate 12 has a complicated shape, the soft film 3 is not stretched unevenly and the transfer surface 12a and the soft film 3 are sufficiently adhered to each other. Can do. As a result, it is possible to ensure good print quality without causing printing unevenness or pattern deformation.

図１（ｄ）は被印刷物押付工程に続いて、塗料１１が転写された被印刷物１２を軟質膜３から剥がす被印刷物取出工程を示している。必要に応じて、ポンプＰによって容器２内に空気を供給し、軟質膜３を膨らませながら被印刷物１２を軟質膜３から剥がせば、軟質膜３と被印刷物１２の被転写面１２ａとの接触面に負圧を発生させることなく、被印刷物１２を軟質膜３から容易に剥がすことができる。   FIG. 1 (d) shows a printed material take-out step for peeling the printed material 12, to which the coating material 11 has been transferred, from the soft film 3 following the printed material pressing process. If necessary, air is supplied into the container 2 by the pump P, and the printed material 12 is peeled off from the soft film 3 while the soft film 3 is inflated, so that the contact between the soft film 3 and the transferred surface 12a of the printed material 12 occurs. The printed material 12 can be easily peeled from the soft film 3 without generating negative pressure on the surface.

以上の工程により、軟質膜３から被印刷物１２の被転写面１２ａへの塗料１１の転写が完了する。転写後に軟質膜３に残った塗料１１は、クリーニング用の粘着テープによって取り除くことができる。   Through the above steps, the transfer of the coating material 11 from the soft film 3 to the transfer surface 12a of the substrate 12 is completed. The paint 11 remaining on the soft film 3 after the transfer can be removed with a cleaning adhesive tape.

以上詳述したことから明らかなように、本実施形態によれば、中間転写工程を不要とするとともに、被印刷物毎の凹版印刷原版と軟質パッドの取り替えを不要とすることで、作業時間の短縮と印刷コストの低減を図ることができ、さらに、被印刷物が複雑な形状の場合であっても印刷品質の低下を招くことのない転写方法及び転写治具を提供することができる。   As is clear from the above detailed description, according to the present embodiment, the intermediate transfer process is unnecessary, and the replacement of the intaglio printing original plate and the soft pad for each substrate is not required, thereby shortening the work time. In addition, it is possible to provide a transfer method and a transfer jig that do not cause a decrease in print quality even when the printed material has a complicated shape.

なお、本発明は上述した実施の形態に限定されるものではなく、本発明の主旨を逸脱しない範囲で種々の変更を施すことが可能であることは言うまでもない。   Note that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

例えば、本実施形態においては、インクジェットプリンタ１３に転写治具１を設置して軟質膜３に印刷を行っているが、軟質膜３のみを設置して印刷を行い、印刷が完了した軟質膜３を容器２に取り付けることもできる。   For example, in the present embodiment, the transfer jig 1 is installed in the ink jet printer 13 and printing is performed on the soft film 3. However, only the soft film 3 is installed and printing is performed, and the soft film 3 is printed. Can also be attached to the container 2.

また、図１（ｂ）に示す軟質膜変形工程において、軟質膜３が型面５の全面に完全に密着する位置まで軟質膜３を変形させているが、軟質膜３が型面５の一部に接触する位置までの変形にとどめることもできる。この場合には、図１（ｃ）に示す被印刷物押付工程において、例えば、容器２とポンプＰを接続している配管１０に配置したバルブ（図示せず）を開栓して、容器２内の空気を大気に開放した状態で、被印刷物１２の被転写面１２ａを軟質膜３に押し付ければ、被転写面１２ａを軟質膜３に押し付ける押付圧によって、型上容器内空間８内の空気が外部に排出され、軟質膜３と型面５とを密着させることができる。   Further, in the soft film deformation step shown in FIG. 1B, the soft film 3 is deformed to a position where the soft film 3 is completely adhered to the entire surface of the mold surface 5. It is also possible to limit the deformation up to the position where it touches the part. In this case, in the printing material pressing step shown in FIG. 1C, for example, a valve (not shown) arranged in the pipe 10 connecting the container 2 and the pump P is opened to If the transfer surface 12a of the substrate 12 is pressed against the soft film 3 in a state where the air is released to the atmosphere, the air in the mold upper container inner space 8 is pressed by the pressing pressure that presses the transfer surface 12a against the soft film 3. Is discharged to the outside, and the soft film 3 and the mold surface 5 can be brought into close contact with each other.

この転写方法によれば、仮に型４の成形精度が若干悪く、型面５に多少の成形不良凹部が存在しているような場合であっても、軟質膜３を型面５の成形不良凹部に沿って変形させることなく、成形不良凹部の存在に左右されずに、良好な印刷品質を確保することができる。   According to this transfer method, even if the molding accuracy of the mold 4 is slightly poor and there are some molding defects on the mold surface 5, the soft film 3 is formed into the molding defects on the mold surface 5. Therefore, it is possible to ensure good print quality without being influenced by the presence of the defective molding recess.

また、本実施形態においては、軟質膜３の塗料１１が印刷される被印刷面３ａに鏡面仕上が施されているが、印刷する絵柄に微細パターンが含まれている場合には、図４に示すように、軟質膜の塗料が印刷される被印刷面に微細凹凸加工が施された微細凹凸付軟質膜２０を用いるとよい。   In the present embodiment, the surface to be printed 3a on which the coating material 11 of the soft film 3 is printed is mirror-finished. However, when a pattern to be printed includes a fine pattern, FIG. As shown, it is preferable to use a soft film 20 with fine unevenness in which a fine uneven process is performed on a printing surface on which a soft film paint is printed.

微細凹凸付軟質膜２０の凹部２１と凸部２２の双方が抵抗となることにより塗料の側方への流動が抑制されるため、軟質膜２０に微細パターンの絵柄を印刷した場合であっても、この絵柄が崩れることなく保持され、印刷品質の低下を招くことなく、微細パターンの転写が可能となる。   Since both the concave portion 21 and the convex portion 22 of the soft film 20 with fine unevenness become resistance, the flow of the paint to the side is suppressed, so even when a pattern of a fine pattern is printed on the soft film 20 The pattern is held without breaking, and a fine pattern can be transferred without deteriorating the printing quality.

この凹部２１と凸部２２の細分化の程度により、塗料の流動を抑制する効果は異なり、微細凹凸が細分化されるほど、塗料の流動を抑制する効果が高まる。したがって、絵柄の微細パターンの程度に応じて最適な微細凹凸を有する微細凹凸付軟質膜２０を用いることが望ましい。   The effect of suppressing the flow of the paint varies depending on the degree of subdivision of the concave portion 21 and the convex portion 22, and the effect of suppressing the flow of the paint increases as the fine unevenness is subdivided. Therefore, it is desirable to use the soft film 20 with fine unevenness having the optimal fine unevenness according to the degree of the fine pattern of the pattern.

なお、この微細凹凸加工をフォトエッチングにより行う場合には、エッチングの加工精度の限界により、凹部２１と凸部２２の寸法が制約され、凹部２１および凸部２２の幅は０．１μｍ以上となる。   Note that, when this fine unevenness processing is performed by photoetching, the dimensions of the recesses 21 and the protrusions 22 are restricted by the limit of the etching processing accuracy, and the widths of the recesses 21 and the protrusions 22 are 0.1 μm or more. .
