Screen printing and finishing in use

Screen printing meshs are often used on the printing press. In the process of screen printing, if there is a certain problem, it will affect a lot of troubles. If this situation is not resolved one day, it will always plague production.

So how do you operate in the real screen printing mesh?

Before printing, check whether there is any dirty or dust on the glass surface of the film and the surface of the film. It is best to wipe it with cotton yarn and alcohol before cleaning. The surface of the film with silver halide attached is the front side, and the shiny side of the film base is the reverse side. When printing on the plate, the film surface of the film and the emulsion surface of the screen should be tightly bonded, and the bite line should be left for exposure. The exposure time should be determined according to the type of photosensitive thorn, the coating thickness of the photosensitive film, the blackness of the positive image, and the printing requirements.

In the plate making process, according to the specified original and drawing surface, select the appropriate texture and the mesh number of the mesh, and select the appropriate photosensitive glue according to the actual requirements to ensure the ideal printing effect of the substrate.

Printing speed. Printing speed has a very important influence on the amount of ink supplied and the uniformity of the ink. When the screen printing machine is printing, the printing speed is determined based on the actual printed matter.

After the speed is adjusted, it can be fixed for continuous printing.
