[0002] Screen printing is a technology that transfers the ink of text, pictures, photos, anti-counterfeiting manuscripts to the surface of paper, fabrics, plastics, leather and other materials through processes such as plate making, inking and pressurization, so as to batch copy the contents of the manuscripts. The current curved glass printing methods usually include the following methods: 1. Pad printing, which has a pad printing rubber head, which is not easy to print on the side of the curved glass, and the printing thickness of the pad printing ink is relatively thin, and it needs to go through multiple printing and baking procedures. The pad printing rubber head requires the product to stay under it before printing, which increases the time consumption, limits the size of the printed product, and cannot print oversized products; 2. Spray printing, spraying the ink, the ink sprayed on the high part of the curved glass will flow from high to low, and the thickness is uneven and difficult to control; 3. Photolithography uses a mask and a light source to print on the curved glass, but the photolithography manufacturing process is complicated (coating, exposure, development, etching, cleaning, etc.), and the cost is relatively high.
