When was screen printing invented

Screen printing originated in China and has a history of more than 2,000 years. As early as the ancient Chinese Qin and Han Dynasties, there was a folder printing method. In the Eastern Han Dynasty, the method of batik batik was widespread, and the level of printed products also increased. To the great cause of the Sui Dynasty, people began to use the frame with a stretched net to carry out printing, so that the folder printing process developed into a screen printing. According to historical records, the exquisite costumes worn by the court during the Tang Dynasty were printed in this way. By the Song Dynasty, silk screen printing had developed and improved the oil paint originally used. It began to add starch-based rubber powder to the dye to make it a paste for screen printing, making screen printing products more colorful.

Screen printing is a major invention in China. The United States "Serigraphy" magazine has commented on China's screen printing technology: "There is evidence that the Chinese used the stables and stencils two thousand years ago. The clothing of the early Ming Dynasty proved their competitive spirit and processing technology. The invention of screen printing has promoted the development of human material civilization in the world. Today, two thousand years later, the screen printing technology has been continuously developed and has become an indispensable part of human life.
