Screen printing refers to using a silk screen as a plate base and using a photosensitive plate making method to create a screen printing plate with graphics and text. Screen printing consists of five major elements, screen printing plate, scraper, ink, printing table and substrate.

Printing is carried out using the basic principle that ink can pass through the graphic part of the screen printing plate, but ink cannot pass through the non-graphic part. When printing, pour ink into one end of the screen printing plate, use a scraper to apply a certain amount of pressure on the ink part of the screen printing plate, and at the same time move towards the other end of the screen printing plate at a constant speed. The ink is removed from the image and text by the scraper during the movement. Part of the mesh is extruded onto the substrate.

The origin of silk screen printing:

Silk screen printing first originated in China and has a history of more than 2,000 years. The clip-on printing method appeared as early as the Qin and Han Dynasties in ancient China. By the Eastern Han Dynasty, the valerian batik method had become widely popular, and the level of printed products had also improved. During the Daye period of the Sui Dynasty, people began to use frames stretched with silk mesh for printing, and the sandwich printing process developed into screen printing.

According to historical records, the exquisite costumes worn in the court of the Tang Dynasty were printed using this method. In the Song Dynasty, screen printing developed again, and the original oil-based paint was improved, and starch-based glue powder was added to the dye to turn it into a slurry for screen printing, making the colors of screen printing products more brilliant.
