Description

TECHNICAL FIELD

[0002] Screen printing refers to using silk screen as a plate base, and making a silk screen printing plate with graphics through a photosensitive method. Screen printing is composed of five elements, a silk screen printing plate, a squeegee, ink, a printing table, and a printing material. It uses the basic principle that the graphic part of the silk screen printing plate can pass through ink, and the non-graphic part cannot pass through ink to print. When printing, ink is poured into one end of the silk screen printing plate, and a squeegee applies pressure to the ink part of the silk screen printing plate while moving at a constant speed to the other end of the silk screen printing plate. The ink is squeezed from the graphic part of the screen printing plate onto the printing material by the squeegee.
