In the glass industry, there are two methods for printing patterns on glass, one is screen printing and the other is UV printing.

In the glass industry, there are two methods for printing patterns on glass, one is screen printing and the other is UV printing. Glass screen printing is to make a screen according to the customer's drawings. During printing, the ink is transferred to the glass through the mesh of the graphic part by the squeeze of the squeegee, forming the same as the original. The screen is printed with a computer-drawn pattern. Film, and then made of film and photosensitive glue. Both the pattern and the text can be changed, and the ink must be a special ink for glass screen printing.

UV printing is also called inkjet printing. It first draws on the computer, and then prints the required patterns through the print head. The principle of printing is similar to that of ordinary inkjet printers. So in the glass industry, is UV printing or screen printing more suitable? The editor lists their renderings for you:

Comparison of screen printing and UV printing process characteristics in glass printing

1. The color types of screen printing are relatively small, because screen printing glass can only screen one color at a time. If you need to screen multiple colors, you need to produce multiple screens to screen different colors, and UV printing can be one-time Print it out, there is no need to make another screen, only the computer map is drawn.

2. Screen printing glass cannot produce gradient colors. UV printing can print brightly colored and beautiful graphics. Gradient colors can be printed only once.

3. Finally, the adhesion of the printing color. The screen printing ink will add a curing agent to the glass surface during screen printing, so that the ink will be better absorbed on the glass surface. It will not fall off without using a sharp tool to scrape it. Although UV printing will not The glass surface is sprayed with a coating similar to a curing agent, but it will easily fall off, especially as time goes by, the printed pattern will fall off layer by layer. This is undoubtedly the Achilles heel of UV printing. A better solution.

Glass screen printing is generally used on electronic products that require relatively high screen printing. The screen printing technology used in home appliance glass produced by Tairong Glass can ensure that the ink will not fall off for a long time. Uv printing is often used on some home glass decorations, such as sliding doors, to bring beautiful visual enjoyment to our home.
