Problems solved by technology

Therefore, when the printing plate is manufactured, the heating of the heating head is used to cause the thermal deformation of the microporous plate more than necessary, so when the printing plate is manufactured, the problem of poor dimensional reproducibility arises
[0013] Through the above description, in screen printing, it is difficult to satisfy image characteristics at the same time, such as avoiding too fine ink dots in the image area, and fast drying characteristics

example

[0099] The present invention will be described in more detail through examples as follows, but the present invention is not limited by these examples without departing from the technical idea of ​​the present invention. For example, the resolution and type of the heating head may also be different from the resolution and type described herein. The types and regulations of materials, such as release agents, are more likely to be different from those described.

[0100] In addition, the measurement and evaluation described in the examples are performed in the following method.

[0101] (1) Printing plate processing method

[0102] First, for each screen printing original plate (hereinafter referred to as the original plate) prepared in each example and comparative example, a contact surface with a heating head, that is, a porous resin film coated with a wire-drawing spindle contains 5 parts Weight of polyether modified silicone resin oil (TSF400, product name of GE Toshiba Silicone ...

Embodiment 1

[0139] (Preparation of resin mixed solution)

[0140] Resin: 100 parts by weight of water polyurethane (AdecaBon Titer-HUX-401 from AsahiDenka),

[0141] Foam stabilizer: 5 parts by weight of higher fatty acid reagent (produced by Sun Nopco Co., Ltd. named SN Foam 200)

[0142] Thickening agent: 5 parts by weight of carboxymethyl cellulose (Dai-ichi Kogyo Seiyaku's product is AG GUM).

[0143] The resin mixed solution was foamed and stirred for 25 minutes with a stirrer (product name of Aicoh Manufacturing Company, Ken Mix Aicoh PRO) at a stirring rate of 500 rpm and a foam containing the resin mixed solution with a foam magnification of 7.0 was prepared. Then, quickly change the weight to 52g / m 2 The coating amount of one layer of high-quality paper with a coating rod is 15g / m 2 The solution is dried, and the porous resin film is formed while obtaining a heat-sensitive original plate for screen printing.

Embodiment 2

[0147] The resin mixed solution with the same structure as in Example 1 was subjected to a foaming treatment, and the same stirrer was used to stir at a stirring rate of 500 rpm for one minute to prepare a foam containing the resin mixed solution with a foam magnification of 1.1. Then quickly change the weight to 52g / m 2 Use a paint stick to coat one layer of high-quality paper with a coating amount of 15g / m 2 The solution is dried, the porous resin film is formed, and the screen-printed heat-sensitive original plate is obtained.

[0148] The average pore diameter of the porous resin film of the obtained original plate is 5.2μm, and the coating density is 0.39g / cm 2 , Its physical properties are shown in Table 1.

[0149] Similar to Example 1, after the release layer is formed on the obtained original plate, the printing plate is processed by the heating head, and printing is performed.

[0150] As a result, as shown in Table 1, satisfactory results were obtained for all hole bloc...

Abstract

The invention relates a source sheet for stencil printing comprising: a porous resin film formed on a surface of a porous support material, wherein air permeability of the porous support material and porous resin film is in the following range: the air permeability of the porous support material: 90 s / 100 cc or less; and the air permeability of the porous resin film: 600 a / 100 cc or less; preferably, the air permeability of the porous support material <= the air permeability of the porous resin film. According to the source sheet and plate manufacturing method of the present invention, the plate for the stencil printing can be obtained which is superior in the pore block property and in which the thermal deformation of the source sheet during the plate manufacturing is suppressed.

Description

Technical field [0001] The invention relates to a screen printing original plate, a method for processing a printing plate for screen printing with the original plate, and a screen printing method using the printing plate. Background technique [0002] As a screen printing original plate (screen original plate), a thermal original plate that is irradiated by infrared rays or perforated by a heating head is known. An adhesive is commonly used to bond the thermoplastic film and the porous tissue paper to each other to obtain the original board. [0003] However, as a screen printing apparatus using a thermal original plate, a rotary screen printing device and a simple pressure type screen printing device are mainly known. [0004] In these printing devices, the ink passes through the holes on the film corresponding to the image area from the tissue paper side of the original plate, and is transferred to the printing paper to complete printing. [0005] In the usual screen printing ...
