When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part on the screen printing plate with a scraper, and move towards the other end of the screen printing plate at a constant speed, and the ink is moved by the scraper from the image and text during the movement. Part of the mesh is extruded onto the substrate.

Screen printing direct plate making (CTS) means that the computer directly outputs the image to the screen printing plate, and forms a printing plate after development. It is a digital production method of the image carrier in screen printing. It is directly controlled by the computer. or silkscreen output. It does not require film printing, and the computer-to-plate technology CTS of screen printing has the same meaning as CTP in offset printing.
