Description

Technical Field

[0001] The utility model relates to an annular silk-screen printing tool. Background Art

[0002] Screen printing is also called silk screen printing. This technology refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Printing is based on the basic principle that the mesh holes of the image part of the screen printing plate can pass through the ink, while the mesh holes of the non-image part cannot pass through the ink. When printing, pour ink at one end of the screen printing plate, use a scraper to apply a certain pressure to the ink part on the screen printing plate, and move at a constant speed toward the other end of the screen printing plate. The ink is squeezed from the mesh holes of the image part to the substrate by the scraper during movement. At present, most of the screen printing tools on the market are manual. The main reason is that the machine-processed screen printing tooling equipment is large and expensive, which leads to many screen printing companies still using traditional manual printing, which has the problem of low production efficiency and is not conducive to the development of the industry in the long run.
