Silk Screen printing types

Silk Screen printing types

Screen printing can be divided into many types according to its format, printer type, ink properties and type of substrate, but its 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 scraper plate moves.
2. Flat screen curved screen printing: Flat screen curved screen printing is a method of printing a flat screen printing plate on a curved surface substrate (such as a ball, cylinder, cylinder, 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 printing: Rotary screen printing is a printing method in which a cylindrical screen plate is equipped with a fixed squeegee, and the cylindrical printing plate and the substrate move simultaneously at an equal linear speed.
4. Indirect screen printing: The first three methods all use printing plates to directly print on the substrate, but they can only print some regular geometric shapes, such as planes, cylindrical surfaces, conical surfaces, etc. For those with complex shapes, edges and depressions, Special-shaped objects such as surfaces must be printed by indirect screen printing. The process often consists of two parts: flat screen printing and transfer printing, that is, the screen printing image is not directly printed on the substrate, but is printed first. On the flat material, transfer it to the substrate using a certain method. One method of indirect printing is to first use flat screen printing to print an image on flat glass, then use a flexible silicone head to absorb the ink image from the glass plate like a stamp, and then pad print it onto the special-shaped glass. Above: Another method of indirect screen printing is decal transfer, such as: screen printing decal + thermal transfer, screen printing decal + pressure-sensitive transfer, screen printing decal + solvent activated transfer print. Indirect screen printing has become a major area of ​​the printing industry.
