What is going on with UV flatbed printer coating

In theory, UV flatbed printers can print any flat data, but due to the differences in the characteristics, density, UV ink adhesion, flexibility and other functions of different materials, some special industrial materials will have inks when they are printed directly with UV flatbed printers. Technical problems such as poor adhesion to the substrate, peeling, falling, and unclear pictures. For the printing of these special materials, it is necessary to coat the surface to improve the adhesion of the substrate.

Commonly used coatings for UV flatbed printers include glass, ceramic tile, PPP, metal, and leather coatings. Among them, glass, metal, and acrylic coatings are more commonly used, which is also determined by the appearance of these two types of materials. The use of coatings that match the substrate can significantly improve the adhesion of UV inks. Do not mix them.

UV flatbed printer coating basically has the characteristics of high adhesion, full transparency, and high gloss. After coating the UV coating on the substrate, it is cured to form a fully transparent coating, which can better absorb the UV ink and significantly improve the adhesion of the UV ink on the substrate. Only a small amount of coating is needed to obtain a stable and uniform surface coating on such a substrate, and then better absorb the UV ink and improve the adhesion of the UV ink.
