UV printer is a common fast inkjet printing equipment in the current market. It has the advantages of rapid UV curing, good environmental tolerance and high printing accuracy. More and more enterprises have replaced traditional processes such as silk screen printing and offset printing with UV printing.
First of all, UV flat-panel printer can print any plane material in theory. However, due to the differences of surface characteristics, density, adhesion and flexibility of UV ink of different materials, some special industrial materials will have technical problems such as poor adhesion of ink to substrate, peeling, falling off and unclear pattern when printing directly with UV flat-panel printer. Then for the printing of these special materials, it is necessary to make coating treatment on the surface to improve the adhesion of the substrate.
Secondly, the commonly used UV printer coatings include glass, ceramic tile, PP, metal, leather coating, etc. Among them, glass, metal and acrylic coatings are the most commonly used, which is also determined by the surface properties of these two kinds of materials. Using the coating matching with the substrate can significantly improve the adhesion of UV ink. Do not mix it.
In addition, UV printer coatings basically have the characteristics of high adhesion, full transparency and high gloss. After the UV coating is coated on the substrate, it is cured to form a layer of fully transparent coating, which can better absorb UV ink and significantly improve the adhesion of UV ink on the substrate. With only a small amount of coating, a stable and uniform surface coating can be obtained on such a substrate, so as to better absorb UV ink and improve the adhesion of UV ink.
It is easy to apply a thin layer of UV coating on the surface of the base material, and it is easy to use a thin layer of UV coating on the surface of the base material. There are also a few coatings that need to be baked. Most of the coating liquid of UV printer has pungent smell. It is recommended to wear masks and gloves when using.
