The screen printing process of glass is based on the principle of screen printing, printing ink onto the surface of the glass, and then using the curing measures of the ink, the printed pattern is firm and durable. The process is as follows: stretching net → sizing → drying → printing → development → drying ↓ flat glass → cutting → edging → cleaning and drying → 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. Screen selection 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. The selection of the frame is relatively regular, the deformation of the frame is aluminum alloy frame, its size should be larger than the pattern, the specific size should be the outer edge of the pattern should be between 70 ~ 100mm frame, this article will Introduce the manual large stretcher. The stretcher is one of the printing equipments and one of the necessary equipment for making the screen version. However, it should be clearly stated that the use of the stretcher alone does not play a typographic role and requires joint screen printing. The special machinery is used together to play a special auxiliary function. The material of the mesh frame, the size of the frame, the shape and the flatness after processing, the strength and the aging treatment, etc., are directly affected by the tension and tension of the screen. In most cases, the main reason is that the tension of the mesh stencil is reduced due to insufficient frame strength. When the tension of the wire mesh machine reaches the required tension, the frame is raised against the wire mesh, so that the wire mesh is affected by the friction resistance of the frame when there is no wire mesh, so the tension is easily uniform. According to the requirements of the product process scale, the ink-adjusting staff will supply the long-term products according to the process card, and the new products will be requested according to the drawings to receive the corresponding functional inks. When collecting, you should review the following contents: whether the ink color of the same model and different batch numbers is the same; whether the ink thickness of the same model and different batch numbers is consistent. After confirming the correctness, fill out the warehouse receipt and get the application. Article source address: http://
