Problems solved by technology

[0003] At present, in the screen printing process, jagged burrs often appear on the edge of the printing ink film. Usually, the edge of the screen printing plate image is not smooth and tidy due to the low resolution of the photosensitive adhesive or insufficient exposure time.

Embodiment Construction

[0018] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be further described below. Of course, the present invention is not limited to this specific embodiment, and general replacements known to those skilled in the art also fall within the protection scope of the present invention. The beneficial effects of the present invention will be described in detail in conjunction with the embodiments.

[0019] like figure 1 As shown, the present invention provides a kind of screen printing plate-making process, comprises the following steps:

[0020] S1. Coating photosensitive glue, evenly coating the photosensitive glue on the screen and drying it thoroughly;

[0021] S2, put the negative film on the printing surface of the screen, and then expose it in a vacuum exposure machine;

[0022] S3. Remove the screen from the exposure machine, remove the negative film, first moisten the surface of the screen ...

Abstract

The invention relates to a silk-screen printing mask-making technology. A silk-screen image after exposure development is subjected to edge uniformity detection, and if a notch exists in the edge, theedge notch is exposed again to ensure the uniformity of the edge of the silk-screen image. When the notch is repaired, original traditional steps of photosensitive glue full coating, exposure and development are discarded, the large part of image is on a silk screen, thus a negative film copy is aligned at the image, thus the negative film copy covers the image area, the edge of the negative filmcopy is directly coated with photosensitive glue and exposed, the development step is omitted, meanwhile, the coating amount of the photosensitive glue is greatly decreased, the exposure time of thephotosensitive glue is greatly reduced, and thus the notch is rapidly repaired.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a screen printing plate-making process. Background technique [0002] Screen printing refers to using a screen as a plate base and making a screen printing plate with graphics through a photosensitive plate-making method. Screen printing consists of five major elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the graphic part of the screen printing plate can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the movement. Part of the mesh is extruded onto the substrate. [0003] At presen...
