Glass Screen Printing Process:
Glass Decorative Printed Beautiful Pattern
Silk screen glass is a kind of decorative glass that is applied on the surface of glass by applying glass screen printing process, and then fired at high temperature.
Glass screen printing is the use of screen printing plates, the use of glass glaze, decorative printing on glass products. Glass glaze is also called glass ink and glass printing material. It is a paste-like printing material that is mixed and stirred by coloring material and linking material. The coloring material consists of inorganic pigments and low-melting fluxes (lead glass powder); the linking material is commonly referred to as linoleum oil in the glass screen printing industry. After printing, the glass products are placed in a stove and fired at a temperature of 520 to 600° C. The glaze printed on the glass surface can be consolidated on the glass to form a colorful decorative pattern. If you use silk screen printing with other processing methods, you will get better results. For example, by polishing, engraving, etching, etc., the glass surface is processed before or after printing, and the printing effect can be doubled.
What is the production of screen printing glass? Below, we introduce the specific process of screen printing glass, stretch mesh→ sizing → drying → printing → development → drying ↓ flat glass → cutting → edging → cleaning and drying → printing sinter, although looking at the process is quite simple However, there are many things that need to be noted in the specific operations:
1. Suitable for printing glass
According to the user's requirements, the glass can be cut into regular shapes or irregular shapes, and then it can be processed by edge grinding, cleaning, and drying. Here special attention should be paid to the surface of the glass.
2, the choice of screen mesh
The screen printing plate used for glass printing is the same as a general screen printing plate. The glass printing plate uses synthetic fiber screen mesh, stainless steel screen mesh, and natural fiber screen mesh. When the general color material is printed, the above screen meshes can be used. In general, inexpensive synthetic fiber screen meshes are selected; when used as gold and silver decorations, stainless steel screen mesh cannot be selected. The specifications of the screen mesh generally use 270-300 mesh No.
3, the choice of frame
At present, the more formal and less deformable frame is aluminum alloy frame, and its size should be larger than the pattern. The specific size should be the pattern of the outer edge of the frame should be between 70 ~ 100mm. In addition to the selection of the frame, its strength is very important, the key is that the rigidity in the horizontal direction is sufficient.
4, stretch mesh choice
Combine the screen mesh with the frame. This is the stretch mesh. There are many ways to stretch the mesh, and manual, mobile, and pneumatic methods can be used. At present, advanced pneumatic screens that can stretch high-quality screens are pneumatic stretching machines. The requirement of the stretch mesh is that the tension is uniform, the mesh latitude and longitude are kept vertical, and the adhesive mesh is firm and cannot be relaxed.
Choose the suitable and high quality meshes
The printing plate is most important for screen printing, and the screen mesh is the core of the screen printing plate. No matter how good the frame is, if the mesh is not good or suitable, it will seriously affect the printing effect and customer experience.
