Screen printing refers to the use of a screen as a substrate, and through the photosensitive plate making method, a screen printing plate with graphics. Screen printing consists of five major elements, screen plates, squeegees, inks, printing stations, and substrates. The mesh of the screen printing plate can be transmitted through the ink, and the non-image portion of the mesh can not be printed through the basic principle of the ink. When printing, the ink is poured into one end of the screen printing plate, and a certain pressure is applied to the ink portion on the screen printing plate by the squeegee, and at the same time, the other end of the screen printing plate is moved at a constant speed, and the ink is scraped from the graphic during the movement. Part of the mesh is squeezed onto the substrate.
The most convenient stencil printing was written in the late 19th century. This type of printing is made on a special stencil paper, which is made into a stencil graphic version by a typewriter or a stylus. The stencil printing is carried out with an ink roller, and the desired printing effect can be obtained on the substrate. In stencil printing, the most widely used is screen printing.
Screen printing is to stretch silk fabric, synthetic fiber fabric or metal mesh on the frame, and make screen printing by hand-painting or photochemical plate making. The modern screen printing technology uses a photosensitive material to make a screen printing plate by photolithography (so that the screen hole of the graphic portion on the screen printing plate is a through hole, and the mesh hole of the non-image portion is blocked. Live) oil paintings, prints, posters, business cards, binding covers, merchandise packaging, merchandise signs, printing and dyeing textiles, glass and metal plane carriers.
