The products printed by UV flatbed printers have the reputation of long retention time, strong adhesion and exquisite pictures! Some materials are specially processed before printing with UV Printer, why should it be processed? The surface atomic structure of the material is relatively dense, and the reason why the UV ink can adhere to the surface of the material is that the UV ink corrodes the surface of the material and integrates it to achieve excellent adhesion. If the density is too high, the corrosion effect is not very good, so a coating should be added to enhance the corrosion effect.
So what material is the adhesion of UV ink is not strong? And what should we do with these materials? Let's take a look together next!
