When acrylic plate is applied to UV flat-panel printer, if the corresponding coating is not painted, it will produce inconvenient conditions such as color difference, easy fading, light color and so on. In addition, we must also pay attention to the natural environment of the application. The office environment of UV flat-panel printer must be clean when printing, which can reduce the unqualified rate to a certain extent. The key reasons are as follows:

1. Too much moisture in the air will cause moisture on the surface of the material, and the ink is not easy to dry completely after printing;

2. If there is smoke and dust in the gas, it is very easy to produce sediment on the surface of the material, resulting in white pattern design or missing other colors;

3. It is proposed to use LED backlight and clean office environment, which is also a very good maintenance for the printer nozzle.
