Background

The basic principle of silk-screen printing, namely silk-screen printing, is to print by utilizing the basic principle that the meshes of image-text parts of a silk-screen printing plate are ink-permeable and the meshes of non-image-text parts are ink-impermeable; when printing, ink is poured into one end of the screen printing plate, a scraping scraper plate applies a certain pressure on the ink position on the screen printing plate, and simultaneously the ink moves towards the other end of the screen printing plate, and the ink is extruded onto a printing stock from meshes of the image-text part by the scraper plate in the moving process.

However, for UTG glass, since UTG glass is too thin (T is 0.03mm), the conventional fixing method is not effective, a large amount of cracks, scratches and ink overflow are easily caused to UTG glass during the screen printing process, and meanwhile, since UTG glass is too thin, the conventional fixing method is difficult to fix, so that the error in screen printing of UTG glass is too large.
