[0002] Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the screen printing plate with images can pass through the ink, while the mesh holes of the non-image parts cannot pass through the ink. After screen printing, the screen needs to be cleaned of the pigment on its surface to facilitate subsequent use and storage.
