The screen printing mesh process of glass is based on the printing principle of the screen. The ink is printed on the surface of the glass, and then the ink is cured, and the printed pattern is durable and durable. Many people still don't understand the process of glass screen printing. As a professional manufacturer of screen printing, maishi is familiar with the printing process of glass screen printing.
The process of glass screen printing mesh can be divided into four items.
1. The screen printed glass can be regular or irregular, then be edged and ground, then cleaned and dried for use. Special care should be taken here that there should be no water marks on the glass surface.
2 When printing on glass, the choice of screen printing mesh is also important. The screen printing plate for glass printing is the same as the general screen printing plate. The glass screen printing plate is made of synthetic fiber mesh, stainless steel wire mesh and natural fiber silk. network. When printing general color materials, the above-mentioned screens can be used, generally using inexpensive synthetic fiber mesh; when used as gold and silver decoration, stainless steel wire mesh cannot be selected. The specifications of the wire mesh are generally 270 to 300 mesh.
3. The selection of the frame should be a normal, and the mesh frame that looks better deformed is an aluminum alloy frame. The size should be larger than the pattern, and the specific size should be that the outer edge of the pattern should be between 70 and 100 mm from the frame. In addition to selecting the frame, its strength is very important, the key is that the rigidity in the horizontal direction is sufficient.
4. Stretching the net and the mesh frame, combining the two, this is the stretch net. There are many ways to stretch the net. It can be manually, maneuvered or pneumatic. At present, the more advanced, high-quality screen version is a pneumatic stretcher. The requirement of the stretch net is that the tension is uniform, the web warp and weft are kept vertical, and the adhesive mesh is firm and cannot be slack.
The process of glass screen printing mesh is described above. Screen printing is not only a process but also a problem that needs attention. It is worth noting that there is also the problem of ink, thickness. Whether it is a problem such as ink leakage.
