Screen printing refers to the use of silk screen as a plate base, and through a photosensitive plate making method, made into a screen printing plate with pictures and texts. Screen printing consists of five elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the mesh of the graphic part of the screen printing plate can penetrate the ink, and the mesh of the non-graphic part cannot penetrate the ink for printing. When printing, pour ink on one end of the screen printing plate, use a squeegee to apply a certain pressure to the ink position on the screen printing plate, and at the same time move toward the other end of the screen printing plate at a uniform speed, the ink is moved by the squeegee from the image and text Part of the mesh is squeezed onto the substrate.
Screen printing originated in China and has a history of more than two thousand years. As early as the Qin and Han dynasties in ancient China, the method of printing with valerian has appeared. By the Eastern Han dynasty, the batik method had become popular, and the level of printed products had also improved. In the Sui Dynasty, people began to use silk-screened frames for printing, and the valerian printing process was developed into silk-screen printing. According to historical records, the exquisite clothing worn in the court of the Tang Dynasty was printed in this way. In the Song Dynasty, screen printing developed again and improved the original oil-based paint, and began to add starch-based gum powder to the dye to make it into a slurry for screen printing, making the color of screen printing products more gorgeous.
Screen printing is a great invention in China. The US "Screen Printing" magazine commented on China's screen printing technology: "There is evidence that the Chinese used horsehair and templates two thousand years ago. The clothing of the early Ming Dynasty proved their competitive spirit and processing technology. "The invention of screen printing promoted the development of material civilization in the world. Today, two thousand years later, screen printing technology has been continuously developed and perfected and has now become an indispensable part of human life.
