Screen printing mesh application in glass printing

Screen printing mesh printing industry can have many aspects such as glass printing and clothing printing. Among them, what is the application of screen printing mesh in glass printing? This is a lot of questions that friends in the glass printing industry want to know. Let’s introduce it below.

The application of screen printing mesh in glass printing is described in detail below.

According to the principle of screen printing, the ink is printed on the surface of the glass, and then the curing method of the ink is used, and the printed pattern is firm and durable. The process is as follows: Stretching net→Sizing→Drying→Printing→Developing→Drying 平板 Flat glass→cutting→grinding→cleaning→printing ↓Sintering 1. Suitable for printing glass, according to user requirements, cutting glass, can be the rule The shape can also be an irregular shape, then it is edge-grinded, then washed, and dried for use. Special care should be taken here that there should be no water marks on the glass surface. 2. Selection of screen 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 mesh. 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. Selection of net frame At present, the frame that is relatively regular and not deformed is an aluminum alloy frame, and its size should be larger than the pattern. The specific size should be that the outer edge of the pattern should be between 70 and 100 mm. 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 Select the screen and the net frame to combine 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 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.
