(Summary description)Screen printing can be divided into many types according to its format, printer variety, ink properties and type of substrate, but the printing methods can be divided into the following types. 1. Flat screen flat screen printing: Flat screen flat screen printing machine uses a flat screen plate to print on a flat substrate. During printing, the printing plate is fixed and the scraping plate moves. 2. Flat screen curved screen printing: Flat screen curved screen printing is a method of printing flat screen printing plates on curved substrates (such as balls, cylinders, cylinders, etc.). When printing, the squeegee is fixed, the printing plate moves in the horizontal direction, and the substrate rotates with the printing plate. 3. Rotary screen screen printing: Rotary screen screen printing is a cylindrical screen printing method in which a fixed squeegee is installed in the cylinder, and the cylindrical printing plate and the substrate are synchronously moved at the same line speed. 4. Indirect screen printing: the first three methods all use the printing plate to print directly on the substrate, but only some regular geometric shapes, such as planes, cylindrical surfaces, conical surfaces, etc., can be printed on complex shapes, edges and recesses. Surfaces and other special-shaped objects must be printed by indirect screen printing. The process often consists of two parts: flat screen printing and transfer, that is, the screen printing image is not directly printed on the substrate, but printed first. On the flat material, transfer to the substrate by a certain method. One of the methods of indirect printing is to use flat screen printing to print an image on a flat glass, and then use a flexible silicone head to absorb the ink image from the glass plate like a seal, and then transfer it to a special shape. Surface: Another method of indirect screen printing is decal transfer, such as: silk-screen decal + thermal transfer, screen-print decal + pressure sensitive transfer, screen-print decal + solvent activation transfer Printed. Indirect screen printing has become a major area of ​​the printing industry.
