Preparation method of steel plate for printing

Abstract

The invention discloses a preparation method of a steel plate for printing. The preparation method comprises the following steps that (1) the flat steel plate is fetched and subjected to laser cutting and / or laser punching, and printing patterns are formed on the steel plate; (2) the front surface and the back surface of the steel plate are subjected to roughness treatment, so that the roughness of the front surface and the back surface of the steel plate reaches a certain level; (3), the front surface and the back surface of the steel plate are each covered with a cyclic polymer film through hot pressing or chemical attachment; and (4) the portion, in the area of the printing patterns on the steel plate, of each cyclic polymer film is subjected to gasify stripping through ultraviolet laser engraving. According to the preparation method of the steel plate for printing, the steel plate replaces a screen mesh, the material and structure of a screen are changed, the manufacturing procedures of the screen are decreased, labor input is reduced, and the performance of the screen is improved.

Description

technical field [0001] The invention relates to a method for preparing a steel plate for printing. Background technique [0002] The preparation of existing screen plates for printing is made by coating photosensitive glue on the surface of steel mesh and exposing them through halogen lamps. The film is pasted on the screen through the exposure of the halogen lamp, and then the graphics required by the customer are displayed through development to achieve the purpose of printing and use by the customer. [0003] The existing screen preparation process needs to go through multiple processes such as screen stretching, plate washing, coating, exposure, and imaging, and most of the processes are still done manually, and the assembly line production equipment occupies a large space; at the same time, the screen is in During the hot air drying process, due to the influence of the environment and the oven, tiny particles in the air will fall onto the screen photosensitive adhesive...

[0003] The existing screen preparation process needs to go through multiple processes such as screen stretching, plate washing, coating, exposure, and imaging, and most of the processes are still done manually, and the assembly line production equipment occupies a large space; at the same time, the screen is in During the hot air drying process, due to the influence of the environment and the oven, tiny particles in the air will fall onto the screen photosensitive adhesive, resulting in defects in the customer's product, and the energy loss of the hot air drying screen is large; During the printing process, the glue is always rubbed by the edge of the printed material, which is easy to cause the problem of broken printing plate, and the service life of the customer's screen plate is short
