Classification Introduction Of Flat Screen Printer

Comments · 27 Views

Flat screen printing is used to print on flat substrates, usually the squeegee is moved against the plate, After the printing plate rises and falls, the substrate is changed.

The process is usually composed of two parts: flat screen printing and transfer, that is, the screen printing image is not directly printed on the substrate, but is printed on the flat material first, and then transferred to the substrate by a certain method. One of the methods of indirect printing is to print the image on the flat glass by the flat screen printing method, and then use the elastic silicone head.

Take the ink image from the glass plate as if it is stamped, and then transfer it to the special surface: another variety of indirect screen printing is flower paper transfer, such as: screen printing flower paper + thermal transfer, screen Printing flower paper + pressure sensitive transfer, screen printing flower paper + solvent activation transfer.

Indirect screen printing has become the main category of the printing industry. Screen printing machines (two-plate printing presses are classified as Flat Screen Printer. Flat screen printing is used to print on flat substrates, usually the squeegee is moved against the plate, After the printing plate rises and falls, the substrate is changed.

Curved screen printing machine. The flat screen printing is used to print on the round substrate, usually the squeegee is fixed, the printing plate is moved, the substrate rotates at the same linear speed as the printing plate, and the rotary screen printing machine. Using the cylinder screen, the screen printing machine inside the cylinder, with a wedge-shaped scraper or scraper roller, the linear speed of the plate rotation and the substrate movement is the same.

Electrostatic screen printing machine. Using a stainless steel screen with good conductivity, the electrostatic difference between the positive and negative electrode plates transfers the powder and ink to the surface of the printing part through the through hole of the printing plate. It is a pressureless printing. The appearance of the machine varies with different substrates, but generally includes the input part of the substrate, the printing part, the dry part of the ink fixing and the collection part of the substrate. Among them, the printing part is composed of screen printing plates, electrode plates, and high-voltage installation.
