Silk screen printing is to make a screen printing plate with pictures and texts by using the screen as the plate base and using the photosensitive plate making method. 

Screen printing consists of five elements: screen printing plate, scraper, ink, printing platform and substrate. 

Using the basic principle of screen printing that part of the screen hole can pass through the ink, and part of the screen hole can not pass through the ink. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part of the screen printing plate with a scraper, and move it towards the other end of the screen printing plate at a constant speed. During the movement, the ink is squeezed onto the substrate by the scraper from the mesh of the image and text part.
