Method for manufacturing screen picture with laser

Abstract

The invention relates to a method for manufacturing a screen picture with a laser. According to the method for manufacturing the screen picture with the laser, firstly, a screen with a net arrangementbeing completed is coated with non-photosensitive glue, and then drying is conducted; secondly, after the screen is dried, the screen is taken out and placed on a picosecond laser engraving treatmentplatform; thirdly, parameters of a picture needed by a client are input into laser engraving software, and laser picture engraving operation is executed until the screen picture is completed; fourthly, the manufactured screen is cleaned and dried, and then manufacturing of the screen is completed. According to the method for manufacturing the screen picture with the laser, the screen is coated with the non-photosensitive glue, picture engraving is conducted through picosecond laser equipment, and therefore the production cost of the screen is effectively lowered; the dimension precision of the screen picture is improved, the quality of lines of the high-precision screen is guaranteed, the screen printing technology can be advanced towards finer lines, the technological difficulty of screen production is lowered, generation of a screen waste is effectively reduced, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of screen production, in particular to a method for producing screen graphics by laser. Background technique [0002] At present, the high-precision screen production process needs to go through the process of screen exposure and development, that is, the screen coated with photosensitive emulsion is pasted with film graphics, and the graphics are obtained by development after exposure. In the current technical situation, the usual practice is to coat the screen with a certain thickness of photosensitive emulsion. After the screen plate is dried, put the pre-made film pattern on the surface of the screen plate, then place the fixed film and screen plate on the exposure machine, set the corresponding exposure parameters, and perform vacuum exposure. After the exposure is completed, the screen is developed, that is, the unphotosensitive part of the screen is rinsed with a water gun to obtain a film pattern. In this ca...

Problems solved by technology

In this case, due to the reason of the current photosensitive emulsion, the resolution of the screen pattern is not high, especially it is difficult to achieve a line width below 25 microns, and the current photosensitive emulsion is expensive and the process is complicated. ;In addition, due to the reason of pasting film graphics before exposure, it is also easy to cause pollution on the screen surface during the process of pasting film graphics, resulting in stripping or even scrapping of the screen

These conditions are extremely unfavorable for printing high-precision products, and the operation is cumbersome and slow, so it is of great value to seek a better method for making screen graphics
