Types of coatings for UV flat plate printers
Although uv flat-panel printers can in almost any graphic printing pattern on the material, but due to the characteristics of different material surface, high density, uv ink adhesion, flexibility and other performance difference, causes the ink prone to peel and part of the material, fall off wait for a circumstance, it is need to use special coating to solve this problem. At present on the market common UV plate printer coating type has the following several kinds.
The first kind is glass, ceramic tile coating.This coating is suitable for plexiglass, toughened glass, glazed ceramic tile, crystal and other glass materials with special treatment.At present, there are two kinds of quick-drying coating and baking, the former can be put into UV plate printer to print patterns after wiping, the latter spray gun, need to be put into oven to bake for 20-30 minutes, the temperature is controlled between 80-120 degrees, take out and then print patterns.
