Color printing process of LY profile

For color printing, first extrude a layer of base color on the surface of the profile, and then print. After printing, apply a layer of paint. Because PMMA is light resistant and wear-resistant, the top layer is coated with PMMA. The color printing machine is very expensive, the cost is calculated in meters, the color exchange is very slow, and the adjustment time of the whole machine is particularly long. At the same time, the printing of all sides of the color printing is very troublesome, so the color and pattern are limited. In Germany, it is generally required to have 6-12 designs, which will increase the cost input. Although the top layer of color printing also has a layer of PMMA, PMMA is generally only 10-15 μ m. It has poor light resistance and is not wear-resistant. Most color printing does not add PMMA layer.
