Screen printing refers to the use of a screen as the base, and a photosensitive screen-making method to make a screen printing plate with graphics. Screen printing is composed of five major elements, screen printing plate, squeegee, ink, printing station and substrate. The basic principle of screen printing is that the mesh part of the screen can pass through the ink, and the non-graphic part of the mesh cannot pass through the ink. During printing, pour ink on one end of the screen printing plate, apply a certain pressure to the ink portion on the screen printing plate with a scraper, and move uniformly towards the other end of the screen printing plate. Part of the mesh is squeezed onto the substrate.
