Silk screen printing mesh is short for silk screen, it is just to print a silk screen and print. Brief introduction to the process of screen printing: manuscript → master plate → screen plate → plate printing → development → drying → printing → drying → finished product inspection → printed matter.
The following plate making methods need to be learned in screen printing and screen printing.
1. Direct plate making method for screen printing. The direct plate making method is a method of directly using a photosensitive material to make a plate. When making a screen printing plate, first place the wrist film-based photosensitive film coated with photosensitive material on a workbench, then stretch the wrist screen frame flat on the film base, put the photosensitive paste, and use a soft scraper. Pressure coating to allow it to fully dry. Finally, the plastic film base is peeled off, the photosensitive film wrist screen is developed and dried, and the screen printing is completed.
2. Indirect plate making by screen printing. Indirect plate making is the method of exposing the indirect film first, and then making the plate. Before making a plate, the exposed indirect film is hardened
with a 1.2% H2O2 solution, developed in warm water, and dried to make a peelable graphic film for later use
. When making a plate, the film film surface of the graphic film is tightly adhered to the stretched screen, and the film is compacted with the wet screen by pressing, and then the film base is peeled off and air-dried. The plate-making process ends.
3. Direct and indirect hybrid plate making method for screen printing. The mixed plate-making method is to paste the photosensitive layer on the screen frame with water, alcohol, or photosensitive glue, dry it with hot air, and then remove the base of the photosensitive film. Version.
After using high-quality screen printing, screen printing is not limited by the size and shape of the substrate, and it can be printed on different shaped shapes and uneven surfaces. The layout is soft and flexible, and it is the one with the lowest printing pressure.
