STEP 1: SCREEN PRINTING PRODUCTION
The screen printing working principle is the partter part on the printing board could be transmitted through the Anti-corrosion ink, the non-parttern part cannot.
When printing, the ink is poured into one end of printing board, and a certain pressure is applied to the ink portion on the printing board by scraper, the same time scraper moving to the other side at a contant speed, during the moving period, the pattern part is squeezed on the surface of stainless steel surface(copper/Aluminium/brass or other metal material).
Upon operation, the non-pattern area is all covering by anti-corrosion ink, the pattern area is uncovered.
