Screen is the most important part of screen printing. It is the key to controlling ink flow and printing thickness, and it determines the durability of the screen. In addition, the excellent combination of screen and screen photographic materials is also an important factor in the production of high quality, high precision screen printing. In order to ensure a good combination of the screen and the photosensitive material, the conventional method is to roughen and degrease the new screen to ensure the quality of the screen and prolong the service life of the screen. At the same time, the correct choice of mesh size is also important. The printing plate made of 160 mesh screen often has the problem that the photosensitive film and the screen are not firmly bonded, the printed lines are easy to be thick, and there are problems such as burrs and scratches on the squeegee; The printing plate made by the net has improved printing precision, labor saving and burr reduction when printing; the printing plate made of 360 mesh nylon mesh, the photosensitive adhesive film and the screen are firmly bonded, the ink scraping board is labor-saving, and the printing precision is obvious. Improve, lines and text edges are neat. Lines and spacing up to No. 2 to 0.15 mm.
