Screen printing is the production of screen printing plates by hand-engraved lacquer film or photochemical plate making using silk, synthetic fabrics, or metal screens stretched over a screen frame. In modern screen printing technology, the screen frames are made by photographic plate making using photosensitive materials (so that the screen holes in the graphic part of the screen frame are through holes, while the non-graphic part of the screen holes is blocked). When printing, the ink is transferred to the substrate through the screen holes of the graphic part by the squeezing of the squeegee, forming the same graphic as the original. Screen printing equipment is simple, easy to operate, easy and inexpensive to print and make plates, and highly adaptable. Screen printing is widely used in a wide range of commonly printed products: colorful oil paintings, posters, business cards, framed covers, commodity signs, and printed textiles.
