What is screen printing and what is steel plate printing?

Screen printing belongs to stencil printing, and it is called four printing methods together with lithography, gravure printing and gravure printing. Stencil printing includes copying stencil, engraving stencil, stencil printing and screen printing. The principle of stencil printing is that when printing, the ink is transferred to the substrate (paper, ceramics, etc.). ) pass through the perforation of the template with a certain pressure to form an image or text.

Screen printing is to stretch silk fabric, synthetic fiber fabric or metal screen on a screen frame, and make a screen printing plate by hand carving paint film or photochemical plate making. Modern screen printing technology is to use photosensitive materials to make screen printing plates by photographic plate making (making the screen holes in the graphic part of the screen printing plate be through holes, but the screen holes in the non-graphic part are blocked), such as plane carriers such as oil paintings, prints, posters, business cards, binding covers, commodity packaging, commodity signs, printing and dyeing textiles, glass and metal.

Steel plate printing

Steel plate printing, also known as pad printing, is a special printing method. It can print characters, graphics and images on irregular and irregular surfaces, and now it is becoming an important special printing. For example, the characters and patterns on the surface of mobile phones are printed in this way, and the surface printing of many electronic products such as computer keyboards, instruments and meters is completed by pad printing.

The printing process of steel plate is very simple. It uses a steel (or copper, thermoplastic) intaglio and an arc pad printing head made of silicone rubber. The ink on the intaglio is dipped on the surface of the pad printing head, and then pressed on the surface of the desired object to print characters, patterns and so on.
