Screen printing machines are used in paper, plastics, leather, wood products, glass, ceramics, textiles, etc. At present, a large number of screen printing methods are used in electronic telecommunication industry services, such as manufacturing printed circuits and nameplate signs.

In the screen printing, there are paper, ceramic glass, metal, textile, paint surface and the development of the electronics industry to plastic metal products.

 In order to increase and increase the bonding strength between the printing material and the substrate, the screen printing surface of the substrate should be consciously treated. The surface of the substrate is not processed before the silk screen printing (including removing dust). Some substrates need to be screen printed before printing. The purpose of the treatment is to improve the adhesion of the printing material to the substrate, and to increase the post-screening treatment, such as anodizing, penetrating, ink, and bead foaming, which must be post-treated to meet the requirements. The corresponding treatment method is adopted according to the material of the substrate.
