Screen printing meshs still need a very important link in their use. When we buy a screen printing mesh, we must pay attention to the need to carry out a simple maintenance of the mesh. What is the main way of maintenance?
What is important is that we clean and degrease the mesh of the screen printing mesh. If the mesh is not cleaned in time, it will easily lead to poor screen printing and garbled when it is used next time. If the corresponding degreasing work is not carried out, it will easily lead to delamination of the screen.
Secondly, marking the age and number of meshes on the mesh frame of the mesh is also an important maintenance strategy. This can provide more convenience to the use process.
Finally, during the use of screen printing, contact with sharp objects should be avoided to prevent accidental damage to the mesh.
Before printing on screen printing, check whether there is dirty or dust on the glass surf
ace 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. The thicker the coating layer of the photosensitive film, the longer the exposure time required, so that the film is completely cured. If the image on the image is not strong enough, that is, gray and not black, the exposure time should be shortened, and the development time should be extended accordingly so that the unsensed image portion is completely transparent.
