Glass Screen Printing

2025-08-22

Glass screen printing is a technique of decorative printing on the surface of glass products using screen printing plates and vitreous enamel. The core material is vitreous enamel, usually made of a mixture of inorganic pigments, low melting point fluxes and linkers, which need to be sintered and cured at a high temperature of 520~600℃. After printing to form a long-lasting pattern, that is acid-resistant and moisture-resistant.

This technology is often combined with processes such as polishing and etching, and is widely used in fields such as architectural decoration, furniture design, automotive glass, and artistic creation. It can achieve precise coverage of color images, anti-corrosion layers or conductive materials.

In the glass screen printing process, first, we need to cut the glass according to the user's requirements. It can be a regular shape or irregular shape, and then chamfer the edge grinding process, and then cleaned, dried and ready for use. Special attention should be paid to the fact that there should be no water stains on the surface of the glass when screen printing.

Screen printing plates for glass printing are the same as normal screen printing plates. The most suitable screen printing mesh for glass screen printing is polyester mesh. The mesh count is 270-300 mesh. The choice of screen printing frame is more formal. Not much deformation of the mesh frame is aluminum alloy mesh frame. Its size should be larger than the pattern. The specific size should be the outer edge of the pattern from the mesh frame should be between 70 ~ 100mm. In addition to the choice of screen printing frame, its strength is very important.

The production process of screen printed glass includes the steps of tautening, sizing, drying, tanning, developing and re-drying, etc. In order to ensure the solidity and effect of the pattern, each step needs to be strictly controlled. All of these steps are designed to ensure the precision of the screen and prepare the conditions for screen printing, thus enhancing the solidity and beauty of the pattern in the glass.

Printed glass products will be put in the furnace, with a temperature of 520 ~ 600 ℃ for firing. Print to the glass surface of the glaze in order to solidify in the glass and form colorful decorative patterns. If the screen printing can be use together with other processing methods, it will get more ideal results. For example, the use of polishing, engraving, corrosion and other methods before or after printing on the surface of the glass processing, can double to improve the printing effect.

Silkscreen glass printing with its unique technology, so that a variety of exquisite patterns can be presented on the glass, not only to meet the basic needs of people on the glass, but also living space and office space to bring the ultimate visual enjoyment. So that every corner is full of vitality and vigor. This process not only makes each piece of silkscreen printing glass has become a unique work of art. More modern home decor has injected new vitality.

Screen printed glass is widely used in all corners of people's lives: you can easily find them in the display window, building space partition, building exterior beautification, automobile windshield and inlaid glass and other places. At the same time. They are also widely used in furniture decoration and game tools, as well as countless decorative and artistic creations.

Alternatively, it can be used to temporarily cover an ungraphic portion of the glass surface or to print an additive such as a preservative on a portion of the glass surface so that it is not affected by the etching or frosting process. Sometimes, people also make use of the strong masking ability of screen printing, such as printing a thin layer of conductive material on the glass for making anti-icing or frost devices for windows.

In addition, there is a strong demand for glass screen printing technology in the automotive industry In addition to purely optical color applications using screen printing, various functional layers have been modified conductor pathways and optimal structures, such as the heat conductor on the rear window and the rear window heater.

At present, the glass silkscreen printing technology is changing to a high-tech and high-tech value-added processing areas. We believe that with the passage of time, glass silkscreen printing technology will provide more support for the glass industry and even electronics, construction, energy and other fields.
