Screen printing refers to the use of screen as a base, and through the plate-making method, made with a graphic screen printing plate. Screen printing consists of five elements, screen printing plate, scraper, ink, printing stations and substrates. The use of screen printing plate graphic part of the mesh through the ink, non-graphic part of the mesh can not be printed through the basic principles of ink. Printing in one end of the screen printing plate into the ink, with a scraper of ink on the screen printing plate to impose a certain pressure on the other side at the same time toward the screen printing plate moving at a constant speed, the ink is moving scraper from the graphic Part of the mesh extrusion to the substrate.
Technical Process
Direct plate method
Method: Direct plate making method is first in the plate making the photosensitive material coated on the base of the photosensitive film face up on the work surface, will be stretched wrist net flat on the film base, and then placed in the net box Into the photosensitive paste and pressurized with a soft squeegee coating, after drying thoroughly peeled off the plastic film base, attached to the photosensitive film can be used for the screen silk screen, after development, drying screen system after the screen.
Process: Stretched - Degreasing - Drying - Peeling Substrate - Exposure - Development - Drying - Repair - Seal
Indirect plate making method
Method: Indirect plate-making method is to expose the first indirect film, hardened with 1.2% H2O2 developed with warm water, dried peelable graphics made of negatives, the plate will be the film version of the graphic film and stretched mesh tight , By squeezing the film and wet screen affixed, exposing the film-based, dried with wind to make screen printing screen.
