Problems solved by technology

[0007] However, since a stainless steel mesh is used as a support body, the recovery of the position coordinates after being deformed by the pressure of the squeegee is not good, so that the printed graphics easy to distort
As a result, it is difficult to obtain the desired printing accuracy
In addition, the support has the same mesh structure as the printing screen, and it needs to be plated, so it is expensive.
In addition, a part of the paste (printing ink) will enter the seam (Japanese: 目) of the support screen, and there is a possibility that the above-mentioned paste will adversely affect the printing quality.

Embodiment Construction

[0045] figure 1 The first embodiment of the combined screen plate for contact printing of the present invention is shown. Above-mentioned combination screen plate 1 comprises: frame 2; Screen screen 3 for printing; Box 2.

[0046] The frame 2 is formed in a quadrangular frame shape from a thick member, and is formed in a size such that the scraper can move inside the frame 2 . The frame 2 is made of metal materials such as aluminum or aluminum alloy. In the conventional screen printing plate, the frame 2 has a function of maintaining the tension of the printing screen 3 , but in the present embodiment, the support body 4 maintains the tension of the printing screen 3 . Therefore, the support body 4 plays a role of firmly supporting the printing screen 3 on the frame 2 .

[0047] As the printing screen 3, a metal mesh or a metal mask is used. The metal mesh is a member obtained by weaving fine metal fibers, and for example, a SUS mesh, a tungsten mesh, a high-strength stee...

Abstract

A combined screen plate suitable for contact printing is capable of performing high-precision printing and is high in durability. The combined screen plate (1) includes: a frame (2); a printing screen(3); and a support (4), wherein an inner peripheral portion of the support (4) and an outer peripheral portion of the printing screen contact, and the outer peripheral portion of the support (4) is fixed to the frame. The printing screen (3) is a metal screen, and compared with the printing screen, the support (4) is formed of, during scraping, a metal sheet which has smaller stretching in the planar direction and a smaller amount of displacement in the thickness direction and is high in strength. Therefore, the combined screen plate (1) can be obtained, can suppress stretching of the printing screen (3) in the planar direction during contact printing, and is high in the precision and durability.

Description

[0001] The present invention is a divisional application with the application number 201810064753.7, the application date is January 23, 2018, and the invention name is "Combined screen plate for contact printing". technical field [0002] The present invention relates to a combination screen plate used in contact screen printing. Background technique [0003] In screen printing, in order to cope with fine wire printing (Japanese: ファインライン printing), the thinning of the screen is promoted, and the direct bonding of the printing screen directly to the frame in order to use a low-strength and expensive screen Compared with the structure, the wire mesh panel with combined structure has become the mainstream. The combined screen board is a member that fixes the periphery of the printing screen to the frame via a support. [0004] In the case of a combined screen board, since the load of the printing screen is absorbed by the support during printing, a synthetic fiber screen with...
