Problems solved by technology

This type of construction has the disadvantage that it is complex
Furthermore, the printed image and the achievable resolution are negatively affected by additional coatings which may have to be applied several times in subsequent method steps
If the surface to be printed has a large roughness, the fine mesh screen can be damaged quickly, so only a short service life is achieved

Embodiment Construction

[0066] In the following text, exemplary embodiments of the present invention will be explained with reference to the drawings.

[0067] figure 1 A diagrammatic cross-sectional view of a screen printing screen 1 according to the invention is shown, which has a film 2 as a screen printing stencil carrier. The film 2 has an upper side 3 also called the doctor side and on the upper side 3 a doctor blade 100 with an edge 101 can distribute a printing medium 102 along the upper side 3 (see also figure 2 ). A masking layer 5 is attached as a screen printing stencil on the underside 4 of the film, which can also be called the printing side or substrate side (as it faces the substrate), the masking layer 5 having free and non-masking points or grooves at certain predetermined points 6. These grooves 6 can be located in the overlap with the grooves 7 of the film 2, so that the printing medium 102 can pass through the grooves 7 and 6 in the direction towards the substrate 103 (see ...

Abstract

A screen printing screen, having: a screen printing stencil carrier which is configured as a film which is provided with first recesses which are configured in such a way that they reach from one upper side to the underside of the film, and a screen printing stencil which is configured as a nonmetallic masking layer which is connected fixedly to the underside of the screen printing stencil carrier, the masking layer being provided with second recesses which lie in congruence at least partially with the first recesses of the screen printing stencil carrier in such a way that a printing medium can pass through the first recesses of the screen printing stencil carrier from its upper side in the direction of the underside and through the second recesses of the masking layer to a substrate which can be placed underneath.

Description

technical field [0001] The invention relates to a screen printing screen plate with a screen printing template carrier and a screen printing template. Background technique [0002] During screen printing, a screen printing screen is placed on a printing material or substrate. The screen printing screen has a screen printing template and a screen printing template carrier, and the screen printing template is connected to the screen printing template carrier configured as a screen. The screen is formed from thin polyester or stainless steel wires woven into each other. For possible handling of the screen printing screen, the screen printing screen is stretched compactly in the screen printing frame. [0003] Screen printing screens have free areas that can receive printing media such as ink or paste. If the doctor blade is guided over the screen printing screen, the printing medium passes through the free area of ​​the screen printing screen onto the substrate arranged belo...
