An improved splicing method for direct-write screen plate-making system

Abstract

The invention discloses a splicing improvement method for a direct-writing silk-screen plate-making system. The splicing improvement method is realized by energy homogenization overlapping exposure ofstrip connection positions of an exposure image, wherein the overlapping exposure comprises that adjacent strips on the exposure image have a certain width of region overlapped, and energy homogenization comprises that image data written in a spatial light modulator are subjected to four-corner region data zero-clearing treatment. The splicing improvement method for the direct-writing silk-screenplate-making system adopts the overlapping exposure method for improving the splicing of the image strip splicing parts on a screen plate, and four corners of the image data written in the spatial light modulator are subjected to zero clearing treatment, so that the homogenization of the exposure energy is achieved. The used splicing improvement method has small data treatment quantity and simpleprocess.

Description

technical field [0001] The invention relates to the technical field of screen plate making, in particular to an improved splicing method of a direct-write screen plate making system. Background technique [0002] The traditional screen plate-making system needs to use film to make plates through the plate-making machine. Film is similar to early camera negatives. The process of using film to make a plate is as follows: stick the film with the image on the screen screen plate coated with photosensitive glue, and use a mercury lamp to illuminate the film. There is a graphic part on the film that can transmit light to make the photosensitive glue of the screen plate sensitive. The photosensitive screen is developed, and the unsensitized part will be dissolved by the developer after development, thereby forming a pattern on the screen. [0003] The traditional method of utilizing film plate making has the following defects: [0004] 1. The cost of consumables is high. The tra...
