[0002] Screen printing refers to the use of a silk screen as a base, and through the photosensitive platemaking method, a silk screen printing plate with images is made. When printing, ink is poured into one end of the silk screen printing plate, and a scraper is used to apply a certain pressure to the ink part of the silk screen printing plate, while moving at a constant speed toward the other end of the silk screen printing plate. During the movement, the ink is squeezed by the scraper from the mesh holes of the image part to the substrate.
