Screen printing is a way of Jiangdu printing machine. Screen printing is a printing method in which the graphic part of the fingerprint plate can be omitted to the substrate by ink. The screen printing plate is reticulated, and the plate forms two parts: through-hole and through-hole. When printing, the ink is squeezed by the squeegee plate to leak from the through-hole part of the plate on the substrate. Screen printing machine is for screen printing machine, can be divided into flat and round screen printing machine. ① Doctor blade. A tool that squeezes the ink on the screen onto the substrate. ② Screen interval. The distance between the screen printing surface of screen printing machine and the substrate surface. In the process of imprinting, the screen is separated from the substrate immediately by the screen spacing and screen resilience, so as to ensure the main line contact state between the screen printing surface and the substrate surface in the printing process, which is one of the important conditions to realize the good transfer of screen printing ink. ③ Screen printing plate. Generally referred to as screen. The layout is reticulated, which is a kind of hole plate composed of screen template, screen and screen frame. a. Screen template. A sealing layer attached to a screen by a photosensitive film, diaphragm, or other material to prevent ink leakage from the blank part. b. Wire mesh. The braids used to make the support of screen printing plate mainly include nylon screen, polyester screen and stainless steel screen. c. Net frame. A frame for supporting a wire mesh, made of wood, metal, or other material. It can be divided into two forms: fixed type and adjustable type. ④ Screen printing station. The device for placing the substrate on the screen printing machine absorbs the substrate during printing and generates effective printing pressure together with the ink scraper.
