Description

本発明は、被印刷体の印刷面にうねりや起伏があったり、被印刷体が平面や円柱状でない場合であったりしても高い品質の印刷を行うことができる印刷方法に関する。   The present invention relates to a printing method capable of performing high-quality printing even when the printing surface of a printing medium has waviness or undulations, or even when the printing medium is not flat or cylindrical.

従来、フレックス基板上に導電性ペーストを印刷して配線パターンを形成するために、円筒状の基体表面に絶縁層を形成し、その絶縁層の周面に、配線パターンが形成された印刷板を介して、導電性ペーストを円筒状の基体よりも大型のオフセットドラムに転写し、転写された配線パターンを、オフセットドラムと円筒状の基体の回転周速とを一致させながら、転写・形成した後、保護層を設けて非磁性成分トナーの非接触現像を可能とするトナー担持体を備えた印刷機がある(例えば、特許文献1参照)。   Conventionally, in order to print a conductive paste on a flex substrate to form a wiring pattern, an insulating layer is formed on the surface of a cylindrical substrate, and a printed board on which the wiring pattern is formed on the peripheral surface of the insulating layer. The conductive paste is transferred to an offset drum larger than the cylindrical substrate, and the transferred wiring pattern is transferred and formed while matching the rotational peripheral speed of the offset drum and the cylindrical substrate. There is a printing machine provided with a toner carrier that is provided with a protective layer and enables non-contact development of non-magnetic component toner (see, for example, Patent Document 1).

このような印刷機では、円筒状の基体に設けられた絶縁層の周面に導電性ペーストを転写・形成することにより、スクリーン印刷法よりも繋ぎ目精度がよい配線パターンが印刷できるようになっている。
(例えば、特許文献1参照)。
In such a printing machine, it is possible to print a wiring pattern with better seam accuracy than the screen printing method by transferring and forming a conductive paste on the peripheral surface of an insulating layer provided on a cylindrical substrate. ing.
(For example, refer to Patent Document 1).

特開2010−250196号公報JP 2010-250196 A

ところが、上記従来オフセット印刷機においては、いわゆる中間転写体として、基体よりも大型のオフセットドラムを用いているため、被印刷体の表面にうねりや起伏がある場合、あるいは被印刷体が平面や円柱状でない場合には、中間転写体(オフセットドラム)の導電性ペーストが塗布された面が、うねりや起伏の底の部分あるいは被印刷体の表面に十分に接触しないという現象が発生する。そして、その結果、中間転写体が接触していない部分に導電性ペーストが十分に塗布されず、不十分な印刷(配線パターン)となってしまうという問題がある。   However, in the conventional offset printing press, an offset drum larger than the substrate is used as a so-called intermediate transfer member. Therefore, when the surface of the printing material has undulations or undulations, or the printing material is flat or circular. If it is not columnar, a phenomenon occurs in which the surface of the intermediate transfer body (offset drum) to which the conductive paste is applied does not sufficiently contact the undulations or the bottom of the undulation or the surface of the printing medium. As a result, there is a problem that the conductive paste is not sufficiently applied to a portion where the intermediate transfer body is not in contact, resulting in insufficient printing (wiring pattern).

本発明は、こうした問題に鑑みなされたもので、印刷面にうねりや起伏があったり、被印刷体が平面や円柱状でない場合であったりしても高い品質の印刷が可能な印刷方法を提供することを目的とする。   The present invention has been made in view of these problems, and provides a printing method capable of high-quality printing even when the printing surface has undulations or undulations, or when the printing medium is not flat or cylindrical. The purpose is to do.

この欄においては、発明に対する理解を容易にするため、必要に応じて「発明を実施するための形態」欄において用いた符号を付すが、この符号によって請求の範囲を限定することを意味するものではない。   In this column, in order to facilitate understanding of the invention, the reference numerals used in the “Mode for Carrying Out the Invention” column are attached as necessary, which means that the scope of claims is limited by this reference numeral. is not.

上記「発明が解決しようとする課題」において述べた問題を解決するためになされた発明は、印刷面形成工程及び印刷工程により印刷を行うことを特徴とする印刷方法である。
印刷面形成工程は、機能性材料(7)を、板状の中間転写体(20)に塗布することにより所定の印刷面を形成する工程であり、印刷工程は、中間転写体(20)の面のうち、印刷面形成工程で機能性材料(7)を塗布した面を被印刷体(5)に線接触させつつ、中間転写体(20)から被印刷体(5)に機能性材料(7)を転写することにより印刷を行う工程である。
The invention made in order to solve the problem described in the above “problem to be solved by the invention” is a printing method characterized in that printing is performed by a printing surface forming step and a printing step.
The printing surface forming step is a step of forming a predetermined printing surface by applying the functional material (7) to the plate-shaped intermediate transfer body (20), and the printing step is a step of forming the intermediate transfer body (20). Among the surfaces, the functional material (7) is applied from the intermediate transfer body (20) to the printing body (5) while the surface coated with the functional material (7) in the printing surface forming step is brought into line contact with the printing body (5). 7) is a step of printing by transferring.

このような印刷方法によれば、被印刷体(5)の印刷面にうねりや起伏がある場合、あるいは被印刷体(7)が平面や円柱状でない場合でも高い品質の印刷が可能である。
つまり、機能性材料(7)を用いて、印刷面形成工程により中間転写体(20)に所定の印刷面を形成した後、機能性材料(7)を被印刷体(5)に印刷する際、中間転写体(20)の機能性材料(7)が転写されている面が被印刷体(5)に線接触するようになっている。
According to such a printing method, high-quality printing is possible even when the printing surface of the printing medium (5) has waviness or undulations, or when the printing medium (7) is not flat or cylindrical.
That is, when the functional material (7) is used to print the functional material (7) on the printing body (5) after a predetermined printing surface is formed on the intermediate transfer body (20) by the printing surface forming process. The surface of the intermediate transfer body (20) onto which the functional material (7) is transferred is in line contact with the printing medium (5).

したがって、被印刷体(5)にうねりや起伏がある場合や被印刷体(5)が平面や円柱状でない場合(例えば円錐形状)であっても中間転写体(20)が被印刷体(5)に線接触して機能性材料(7)を被印刷体(5)に印刷していくので、被印刷体(5)のうねりや起伏の底の部分あるいは被印刷体(5)が平面や円柱状でない場合であっても、その表面に機能性材料(7)が印刷される。つまり、被印刷体(5)の印刷面にうねりや起伏がある場合、あるいは被印刷体(5)が平面や円柱状でない場合であっても高い品質の印刷が可能となる。   Therefore, even when the printing body (5) has undulations or undulations, or even when the printing body (5) is not flat or cylindrical (for example, conical shape), the intermediate transfer body (20) is the printing body (5 ), The functional material (7) is printed on the printed body (5), so that the undulation or undulation of the printed body (5) or the printed body (5) is flat or Even if it is not cylindrical, the functional material (7) is printed on the surface. That is, high-quality printing is possible even when the printing surface of the printing medium (5) has waviness or undulations, or when the printing medium (5) is not flat or cylindrical.

なお、ここで「円柱状」とは、被印刷体(3)の中心軸に垂直な断面の円周部分が円形あることを意味しており、内部が中空の円筒形状であってもよい。
また、「所定の印刷面」とは、被印刷体(5)に印刷される印刷パターンを得るための文字や画像あるいは電子回路の配線パターン(配線部分と絶縁部分のパターン)などを意味している。
Here, the “columnar shape” means that the circumferential portion of the cross section perpendicular to the central axis of the printing medium (3) is circular, and the inside may be a hollow cylindrical shape.
The “predetermined printing surface” means a character or image for obtaining a print pattern to be printed on the substrate (5), or a wiring pattern of an electronic circuit (pattern of a wiring part and an insulating part). Yes.

ここで、印刷面形成工程において、中間転写体(20)に所定の印刷面を形成するには種々の方法が考えられるが、請求項2に記載のように、機能性材料(7)を中間転写体(20)に噴射する噴射手段(40)により所定の印刷面を形成するようにするとよい。   Here, in the printing surface forming step, various methods are conceivable for forming a predetermined printing surface on the intermediate transfer body (20). As described in claim 2, the functional material (7) is used as an intermediate material. A predetermined printing surface may be formed by the ejecting means (40) that ejects the transfer body (20).

このようにすると、機能性材料(7)を例えば液状にし、噴射手段(40)によって液滴噴射することで、中間転写体(20)に容易に所定の印刷面を形成することができる。
また、請求項3に記載のように、印刷面形成工程を、機能性材料(7)を、版胴(10)に塗布することにより、版胴(10)に所定の印刷面を形成する塗布工程と、塗布工程で前記版胴(10)に塗布した機能性材料(7)を板状の中間転写体(20)に転写する転写工程と、からなるようにしても、中間転写体(20)に容易に所定の印刷面を形成することができる。
In this case, the functional material (7) is made, for example, liquid, and droplets are ejected by the ejecting means (40), whereby a predetermined printing surface can be easily formed on the intermediate transfer body (20).
Further, as defined in claim 3, the printing surface forming step is performed by applying the functional material (7) to the plate cylinder (10), thereby forming a predetermined printing surface on the plate cylinder (10). The intermediate transfer body (20) may include a process and a transfer process in which the functional material (7) applied to the plate cylinder (10) in the coating process is transferred to the plate-shaped intermediate transfer body (20). ) Can easily form a predetermined printing surface.

また、請求項4に記載のように、中間転写体(20)をPDMS製にすると、中間転写体(20)の表面の濡れ性が低くなり(つまり、撥水性や撥油性が高くなり)、画像パターンでない部分の表面に機能性材料(7)が残り難くなる。したがって、いわゆるエッジが立った精細な印刷が可能となる。   Further, as described in claim 4, when the intermediate transfer member (20) is made of PDMS, the wettability of the surface of the intermediate transfer member (20) is reduced (that is, the water repellency and oil repellency are increased), It is difficult for the functional material (7) to remain on the surface of the portion that is not the image pattern. Therefore, fine printing with so-called edges is possible.

ところで、機能性材料(7)としては、紙に印刷するためのインクなど種々のものが考えられるが、請求項5に記載のように、導電性ペーストであると、被印刷体(5)の表面に、電子回路などで必要とされる電気的に導電性を有する印刷パターンを印刷することができる。   By the way, as the functional material (7), various materials such as ink for printing on paper are conceivable. However, if the conductive material is a conductive paste as described in claim 5, the printed material (5) An electrically conductive printing pattern required for an electronic circuit or the like can be printed on the surface.

(印刷機1の構成)
図1は、本発明が適用された印刷機1の概略の構成及び印刷の原理を示す図であり、印刷機1は、図1に示すように、版胴10、機能性材料塗布ローラ12(以下、塗布ローラ12と呼ぶ)、中間転写体20、印刷部30を備えている。
Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.
[First Embodiment]
(Configuration of printing machine 1)
FIG. 1 is a diagram showing a schematic configuration of a printing machine 1 to which the present invention is applied and the principle of printing. The printing machine 1 includes a plate cylinder 10 and a functional material application roller 12 (see FIG. 1). Hereinafter, it is referred to as an application roller 12), an intermediate transfer member 20, and a printing unit 30.

版胴10は、機能性材料7を印刷する形態(いわゆる印刷パターン)に塗布するための部品であり、アルミニウムなどの金属を円柱状に形成したものである。
塗布ローラ12は、機能性材料7を塗布するための部品であり、図1に示すように、円柱状のローラであり、ローラを回転させることによってローラ表面の機能性材料7が印刷パターンとなるように、版胴10に塗布していく。
The plate cylinder 10 is a component for applying the functional material 7 in a printing form (so-called printing pattern), and is formed of a metal such as aluminum in a columnar shape.
The application roller 12 is a component for applying the functional material 7, and is a cylindrical roller as shown in FIG. 1, and the functional material 7 on the roller surface becomes a printing pattern by rotating the roller. In this manner, the coating is applied to the plate cylinder 10.

中間転写体20は、版胴10に塗布された機能性材料7を転写するためのものであり、PDMS(Poly DiMethyl Siroxaneの略)を平板状に形成したものである。   The intermediate transfer body 20 is for transferring the functional material 7 applied to the plate cylinder 10, and is formed by forming PDMS (Poly Dimethyl Siloxane) in a flat plate shape.

また、中間転写体20は、版胴10から機能性材料7を転写した後、転写面を反転させる(図1では、機能性材料7の転写面を下面から上面に反転させる)反転装置22を有している。   In addition, the intermediate transfer body 20 has a reversing device 22 that reverses the transfer surface after transferring the functional material 7 from the plate cylinder 10 (in FIG. 1, the transfer surface of the functional material 7 is reversed from the lower surface to the upper surface). Have.

印刷部30は、中間転写体20の面のうち機能性材料7が転写された面を被印刷体5に線接触させ、中間転写体20表面の機能性材料7を被印刷体5に転写することにより印刷を行う部分であり、印刷板32及び図示しない移動機構を備えている。   The printing unit 30 causes the surface of the intermediate transfer body 20 to which the functional material 7 is transferred is brought into line contact with the substrate 5 to transfer the functional material 7 on the surface of the intermediate transfer body 20 to the substrate 5 to be printed. This is a portion that performs printing, and includes a printing plate 32 and a moving mechanism (not shown).

印刷板32は、PDMSの板材を平板状に形成したものであり、中間転写体20の上側に平行に配置されている。また、図示しない移動機構は、印刷板32を、被印刷体5に押圧させながら中間転写体20と平行に移動させる機構である。   The printing plate 32 is obtained by forming a plate material of PDMS into a flat plate shape, and is disposed in parallel on the upper side of the intermediate transfer body 20. Further, a moving mechanism (not shown) is a mechanism that moves the printing plate 32 in parallel with the intermediate transfer body 20 while pressing the printing medium 32.

そして、円柱状や円錐形状の被印刷体5を中間転写体20の平面の端に配置し、印刷板32の平面の端が被印刷体5に接触するように、つまり、被印刷体5を中間転写体20と印刷板32で挟むようにする。   Then, the printing body 5 having a cylindrical shape or a conical shape is arranged at the end of the plane of the intermediate transfer body 20, and the end of the plane of the printing plate 32 is in contact with the printing body 5, that is, the printing body 5 is The intermediate transfer body 20 and the printing plate 32 are sandwiched.

その状態で、中間転写体20を固定し、印刷板32を被印刷体5に押し付けつつ、被印刷体5が回転するように中間転写体20と平行に移動させることにより、中間転写体20上の機能性材料7を被印刷体5に印刷できるようになっている。   In this state, the intermediate transfer member 20 is fixed, and the printing plate 32 is pressed against the substrate 5 while being moved in parallel with the intermediate transfer member 20 so that the substrate 5 is rotated. The functional material 7 can be printed on the printing medium 5.

なお、「機能性材料」とは、紙などに文字や画像を印刷するためのインクや電子回路を形成するための導電性ペーストや絶縁ペーストあるいは酸化物半導体ペーストなど何らかの機能を有する材料を示している。
(印刷機1による印刷)
次に、図2に基づき、印刷機1による印刷方法について説明する。図2は、印刷機1による印刷方法の説明図である。なお、本実施形態では、機能性材料7としてインク7を用いる。
“Functional material” refers to a material having some function such as ink for printing characters and images on paper, conductive paste for forming electronic circuits, insulating paste, or oxide semiconductor paste. Yes.
(Printing by printing machine 1)
Next, a printing method using the printing machine 1 will be described with reference to FIG. FIG. 2 is an explanatory diagram of a printing method by the printing machine 1. In the present embodiment, ink 7 is used as the functional material 7.

図2(a)に示すように、塗布ローラ12の表面に所定の印刷パターンのインク7を塗布し、塗布ローラ12を版胴10に押し付けながら回転させることにより、所定の印刷パターンのインク7を版胴10に塗布する。   As shown in FIG. 2A, the ink 7 having a predetermined printing pattern is applied to the surface of the application roller 12, and the application roller 12 is rotated while being pressed against the plate cylinder 10, whereby the ink 7 having a predetermined printing pattern is applied. It is applied to the plate cylinder 10.

その後、図2(b)に示すように、版胴10を中間転写体20に押し付けて回転移動させることにより、版胴10から中間転写体20に所定のパターンのインク7を転写する。
さらに、図2(c)に示すように、中間転写体20を反転装置22により反転させた後、中間転写体20のインク7を転写した平面の端(図2(c)中右端)に被印刷体5を載置し、載置した被印刷体5を印刷板32の平面の端(図2(c)中左端)で押さえる。
After that, as shown in FIG. 2B, the plate cylinder 10 is pressed against the intermediate transfer member 20 and rotated to transfer the ink 7 having a predetermined pattern from the plate cylinder 10 to the intermediate transfer member 20.
Further, as shown in FIG. 2 (c), after the intermediate transfer member 20 is reversed by the reversing device 22, the end of the plane (right end in FIG. 2 (c)) to which the ink 7 of the intermediate transfer member 20 has been transferred is covered. The printing body 5 is placed, and the placed printing body 5 is pressed by the flat end of the printing plate 32 (the left end in FIG. 2C).

そして、図示しない移動機構により、印刷板32で被印刷体5を押し下げつつ印刷板32を中間転写体20と平行に、中間転写体20と重なる向き(図2中左向き)に移動させる。すると、中間転写体20の表面と被印刷体5とが線接触し、線接触した部分でインク7が中間転写体20から被印刷体5に転写され、印刷が行われる。
(印刷機1の特徴)
以上のような印刷機1及び印刷機1による印刷方法では、版胴10から中間転写体20にインク7を転写した後、インク7を被印刷体5に印刷する際、中間転写体20のインク7が転写されている面が被印刷体5に線接触する。
Then, the printing plate 32 is moved parallel to the intermediate transfer body 20 and in a direction overlapping the intermediate transfer body 20 (leftward in FIG. 2) while the printing medium 5 is pushed down by the printing board 32 by a moving mechanism (not shown). Then, the surface of the intermediate transfer body 20 and the printing medium 5 are in line contact, and the ink 7 is transferred from the intermediate transfer body 20 to the printing medium 5 at the line contact portion, and printing is performed.
(Features of printing machine 1)
In the printing machine 1 and the printing method using the printing machine 1 as described above, after the ink 7 is transferred from the plate cylinder 10 to the intermediate transfer body 20, the ink of the intermediate transfer body 20 is printed when the ink 7 is printed on the printing medium 5. The surface on which 7 is transferred comes into line contact with the substrate 5 to be printed.

したがって、被印刷体5にうねりや起伏あるいは、被印刷体5が平面や円柱状でなく円錐形状であっても中間転写体20が被印刷体5に線接触してインク7を被印刷体5に印刷していく。   Therefore, even if the printing medium 5 is wavy or undulated, or the printing medium 5 is not flat or cylindrical but conical, the intermediate transfer body 20 makes line contact with the printing medium 5 and the ink 7 is applied to the printing medium 5. To print on.

したがって、被印刷体5のうねりや起伏の底の部分、あるいは被印刷体5が平面や円柱状でない場合であっても、その表面に被印刷体5に機能性材料7が印刷される。つまり、被印刷体5の印刷面にうねりや起伏がある場合、あるいは被印刷体5が平面や円柱状でない場合であっても高い品質の印刷が可能となる。   Therefore, even if the undulation or undulation bottom portion of the printing medium 5 or the printing medium 5 is not flat or cylindrical, the functional material 7 is printed on the printing medium 5 on the surface thereof. That is, high-quality printing is possible even when the printing surface of the printing medium 5 has undulations or undulations, or when the printing medium 5 is not flat or cylindrical.

具体的に円筒状の被印刷体5に印刷を行った結果を図3に示す。図3(a)に示すように、PDMS製の平板状の中間転写体20に、インク7で蛇の目状の印刷パターンを形成し、その上に円筒状の被印刷体5を載せ、その上にPDMS製の平板状の印刷板32を被せる。   FIG. 3 shows the result of printing on the cylindrical substrate 5 in detail. As shown in FIG. 3A, a serpentine print pattern is formed with the ink 7 on a flat intermediate transfer body 20 made of PDMS, and a cylindrical print body 5 is placed thereon, and then a printed pattern 5 is placed thereon. A flat plate 32 made of PDMS is covered.

そして、図3(b)及び図3(c)に示すように印刷板32を被印刷体5が回転する向きにスライドさせると、図3(d)に示すように、蛇の目のパターンのインク7が中間転写体20から被印刷体5に印刷されることが分かる。   Then, when the printing plate 32 is slid in the direction in which the printing medium 5 rotates as shown in FIGS. 3B and 3C, the ink 7 in the pattern of the snake-eye pattern as shown in FIG. Is printed from the intermediate transfer member 20 onto the substrate 5.

また、図4に示すように、被印刷体5が接着剤のボトルのように円錐形状のものであっても、被印刷体5が円筒状の場合(図3参照)と同様に印刷ができることが分かる。
さらに、被印刷体5の表面に粘着性がある場合であっても、中間転写体20がPDMS製であれば、中間転写体20から被印刷体5に印刷を行う際、被印刷体5からインク7がPDMS製の印刷板32にインク7が再転写されることがなく、高品質・高精度の印刷を行うことができる。
Further, as shown in FIG. 4, even if the printing medium 5 is conical like an adhesive bottle, printing can be performed in the same manner as when the printing medium 5 is cylindrical (see FIG. 3). I understand.
Further, even if the surface of the printing medium 5 is sticky, if the intermediate transfer body 20 is made of PDMS, when printing from the intermediate transfer body 20 to the printing body 5, The ink 7 is not retransferred to the printing plate 32 made of PDMS, and high-quality and high-precision printing can be performed.

つまり、PDMS製の中間転写体20にインク7のような液状やゲル状の機能性材料が塗布されると、PDMSがインク7の液体成分を吸収し、インク7が乾燥状態となる。すると、中間転写体20に対するインク7の離型性が向上するため中間転写体20から被印刷体5にはインク7が容易に転写される。   That is, when a liquid or gel-like functional material such as the ink 7 is applied to the PDMS intermediate transfer body 20, the PDMS absorbs the liquid component of the ink 7 and the ink 7 becomes dry. Then, since the releasability of the ink 7 with respect to the intermediate transfer body 20 is improved, the ink 7 is easily transferred from the intermediate transfer body 20 to the printing medium 5.

そして、被印刷体5に転写されたインク7は、乾燥状態であるので、印刷板32がPDMS性であっても、印刷板32には転写しない。つまり、被印刷体5のインク7が印刷板32に再転写することがないので、印刷パターンの印刷の質や精度が低下することがない。
[第2実施形態]
次に、図5に基づき、第2実施形態の印刷機2について説明する。図5は、第2実施形態における印刷機2の概略の構成を示す図である。なお、第2実施形態における印刷機2では、被印刷体5として、紙やプリント基板あるいはフレックス基板など表面が平らな平板状のものを想定しているが、表面が波状の平板や表面が曲面の被印刷体5、例えば、円柱状などのものであってもよい。
Since the ink 7 transferred to the printing medium 5 is in a dry state, it is not transferred to the printing plate 32 even if the printing plate 32 is PDMS. That is, since the ink 7 of the printing medium 5 is not retransferred to the printing plate 32, the printing quality and accuracy of the printing pattern are not deteriorated.
[Second Embodiment]
Next, based on FIG. 5, the printing machine 2 of 2nd Embodiment is demonstrated. FIG. 5 is a diagram illustrating a schematic configuration of the printing machine 2 according to the second embodiment. In the printing machine 2 according to the second embodiment, the printing object 5 is assumed to be a flat plate having a flat surface, such as paper, a printed board, or a flex board. However, the wavy flat plate or the surface is a curved surface. The substrate 5 to be printed, for example, a cylindrical shape may be used.

第2実施形態における印刷機2は、図5に示すように、第1実施形態における印刷機1と同様に、塗布ローラ12から版胴10に、所定の印刷パターンでインク7を塗布し、その後、版胴10からインク7を中間転写体20に転写する。そして、中間転写体20を反転装置22で反転させるようになっている。   As shown in FIG. 5, the printing machine 2 in the second embodiment applies the ink 7 in a predetermined printing pattern from the application roller 12 to the plate cylinder 10 in the same manner as the printing machine 1 in the first embodiment. Then, the ink 7 is transferred from the plate cylinder 10 to the intermediate transfer member 20. Then, the intermediate transfer member 20 is reversed by the reversing device 22.

第1実施形態における印刷機1では、印刷部30が印刷板32と移動機構(図示せず)を備えていたが、第2実施形態における印刷機2では、印刷部30は、印刷ローラ34、保護板36及び印刷ローラ移動機構(図示せず)を備えている。   In the printing machine 1 according to the first embodiment, the printing unit 30 includes the printing plate 32 and a moving mechanism (not shown).
