Title:
SCREEN PRINTING PLATE AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/059712
Kind Code:
A1
Abstract:
Disclosed are a screen printing plate and a preparation method thereof, same being used to solve the problem in the prior art that using a screen printing plate in glass cement printing may cause the printed pattern to be thick in the middle and thin at the edges, and to easily produce burrs at the edges. In the screen printing plate, a pattern layer comprises a plurality of openings (20) for forming a pattern of a material to be applied, the openings (20) comprising at least two sub-openings (21, 22, 23, 24), the sub-openings (21, 22, 23, 24) progressively decreasing in size in sequence in the horizontal direction along the vertical direction away from the vicinity of a screen (1). Thus, a scraper can squeeze out glass cement (4) from the screen (1) and the region corresponding to the sub-opening (21, 22, 23, 24) closest to the screen (1), and squeeze out glass cement (4) via the plurality of sub-openings (21, 22, 23, 24) progressively reducing in size in the horizontal direction, thereby realizing the uniform output of glass cement (4) at the sub-openings (21, 22, 23, 24) farthest from the screen (1), and at the same time, eliminating burring of the edges of the printed pattern of glass cement (4).
