Difference between screen printing and decal printing

When it comes to glass screen printing, some people will always compare the glass screen printing process with the decal printing process to determine which process is the most suitable for glass.

However, I think each process has its own advantages. If there is one between screen printing and decal printing that can completely replace the other and has more advantages, then one of them must have been eliminated by the market. Since the two processes can coexist, it shows that they have advantages and differences. Let's introduce them to you.

The glass screen printing process is printed by automatic screen printing machine, which can print any pattern and any color.

Due to the physical characteristics of the glass screen printing machine, the printing ink will be thicker, so the surface of the image and text will have a more obvious concave-convex feeling. The screen printing process of the glass screen printing machine is now fully automated, without manual intervention. However, screen printing belongs to monochrome printing, and only one color can be printed at a time, so the production efficiency of multi-color printing will be slower. The color boundary of screen printing is obvious, and gradient color cannot be printed. If you use screen to print multiple color patterns, you need to print multiple times, which will lead to color and pattern deviation. Therefore, we recommend screen printing with a maximum of two colors.

The logo on the glass surface can also be made with decal printing. Many people may be unfamiliar with the decal printing process, and the glass decal printing process can also be understood in this way. The glass products with exquisite color patterns can be made by pasting logo stickers on the glass, and then baking in the heating zone, high temperature zone and cooling zone. The process of decal printing requires manual operation. The quality of the pattern is determined by the skill of the workers, so the cost of decal printing is often higher.

In fact, screen printing and decal printing of glass can bring a beautiful change to the appearance of glass.

However, the printing process of glass screen printing machine is more textured and three-dimensional, while the color sense of glass will be more intense if decal printing is used.
