謂膜厚印刷を行う為の重ね刷り印刷方法及びこれを実現
する印刷機械に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to an overprinting method for performing so-called thick-film printing with a high aspect ratio (film thickness/line width ratio), and a printing machine that implements the same.
（発明の課題）
スクリーン印刷版からスキージの移動に伴って、インキ
を透過させていく所謂スクリーン印刷は、近年様々な分
野に応用されているが、これに伴って、アスペクト比の
高い膜厚の印刷が実現し、かつ要請されている。(Problem to be solved by the invention) So-called screen printing, which allows ink to pass through as a squeegee moves from a screen printing plate, has been applied to various fields in recent years. Printing is both possible and desired.
例えばクリーム半田の印刷では、約１５０μの膜厚の印
刷が要求され、電子回路の素子の印刷では、例えば約３
０ｕの膜厚によるの銀ペーストの印刷が要求され、更に
はプラズマデバイスでは、約８０ｕ〜２５０ｕの膜厚を
有するブラックストライプまたはブラックマトリックス
の印刷が要求されている。For example, when printing cream solder, a film thickness of approximately 150 μm is required, and when printing electronic circuit elements, for example, approximately 3 μm thick is required.
Printing of silver paste with a thickness of 0u is required, and furthermore, in plasma devices, printing of a black stripe or black matrix with a thickness of about 80u to 250u is required.
これ等の印刷については、当然アスペクト比は何れもｌ
を越えており、場合によっては３を越えることも稀では
ない。Of course, for these types of printing, the aspect ratio is l.
It is not uncommon for it to exceed 3 in some cases.
そしてこの様な高アスペクト比を有する所謂膜厚印刷を
スキージの一回の移動によって印刷することは不可能で
ある。It is impossible to perform so-called thick film printing having such a high aspect ratio by one movement of the squeegee.
この為、高アスペクト比を有する膜厚印刷を実行する為
には、必然的に重ね塗り印刷を実行し、所望の膜厚を確
保する訳であるが、是迄行われているスクリーン印刷法
に於ては、重ね塗りの結果インキの縮み、垂れ等の現象
が生じ、高アスペクト比を有する印刷に於て印刷の精度
を確保することは非常に困難となっている。For this reason, in order to perform film thickness printing with a high aspect ratio, it is necessary to perform overprint printing to ensure the desired film thickness, but the screen printing method that has been used until now is In this case, phenomena such as shrinkage and dripping of the ink occur as a result of overcoating, making it extremely difficult to ensure printing accuracy when printing with a high aspect ratio.
これは、既に印刷が行われた印刷面に直接スクリーン印
刷版２を接した状態で更に重ね塗りを行っていることか
ら、既に印刷されたインキの面の形状が重ね塗りの結果
歪められ、縮み現象、垂れ等の現象を生じていたことに
よる。This is because the screen printing plate 2 is in direct contact with the already printed surface and the screen printing plate 2 is applied again, so the shape of the already printed ink surface is distorted as a result of the overpainting, causing shrinkage. This is because phenomena such as dripping and sagging occurred.
本願は、従来の印刷に於けるこの様な欠点を克服し、高
アスペクト比を有する膜厚印刷に於て、極めて高精度の
印刷を得る方法及びその為の装置を提供することを目的
としている。The purpose of this application is to overcome these drawbacks in conventional printing and provide a method and apparatus for achieving extremely high precision printing in film thickness printing with a high aspect ratio. .

る（尚第１図に於て■は、既に形成されている印刷面を
示し、■は、■の印刷面の上にスキージの移動によって
形成されている印刷面を示す。）。That is, when recoating is performed on a printing surface that has already been printed, as shown in FIG. However, if the ink 11 is transmitted through the ink 11, the pressure of the squeegee will distort the ink on the printed surface, which will cause shrinkage and dripping, as in conventional overcoating. (In FIG. 1, ■ indicates a printed surface that has already been formed, and ■ indicates a printed surface that has been formed by moving the squeegee on the printed surface marked with ■.).

クシャー印刷装置を発明し、既に御庁に出願している。By the way, the applicant has discovered that in conventional screen printing devices, the degree of tension on the screen printing plate differs depending on the part where the squeegee moves, and furthermore, the screen printing plate is forcibly stretched by the squeegee during E-printing. Since the printing plate has various drawbacks such as gradual deformation and pattern dimension unevenness, as the squeegee moves, the tip of the squeegee 2 on the ink-holding side as shown in Fig. 5(a). On the opposite side, in order to keep the snap-off angle α between the screen printing plate 3 and the printing surface 4 constant, and to keep the tension in the surface direction of the screen printing plate 3 constant regardless of the moving position of the squeegee. In this structure, a holder 53 is provided, in which the end of the squeegee on the side that holds the ink moves, as shown in Figure 5. As the squeegee moves, the end of the squeegee on the side that holds the ink and the snap-on angle 3 and the ink are held. The screen is oriented perpendicularly to the direction of movement of the squeegee so that both the snap-off angle 2 on the side and the opposite side are constant, and the tension in the surface direction of the screen printing plate 3 is constant regardless of the position of the squeegee movement. The configuration is such that holders 53 and 54 are provided on which both ends of the printing plate move, and the fifth
As shown in Figure 0, as the squeegee moves, the tip of the squeegee keeps the snap-off angle α between the screen printing plate and the printing surface constant on the side opposite to the ink holding side, and the screen The tension in the plane direction of the printing plate 3 is
In order to maintain the same position regardless of the position of the squeegee, the end of the screen printing plate is moved along the linear holder 53, and the other end of the screen printing plate is moved on the side where the tip of the squeegee holds the ink. He has invented a so-called flexure printing device based on a configuration in which a squeegee is movable in a substantially horizontal direction along with the movement of a squeegee, and has already filed an application with the Japanese government.
