How to Print Colors on Transparent Plastic Boxes?

Transparent packaging boxes have many surface printing processes to process. The commonly used printing processes for PET plastic boxes, PVC plastic boxes and PP plastic boxes are: UV printing and silk screen printing.

UV printing of transparent packaging boxes is an offset printing process that transfers ink to the surface of the plastic box through pressure. Silk screen printing allows ink to penetrate directly into the film through small holes. Correctly understanding the difference between these two printing methods can effectively solve many problems of whether the color meets customer requirements.

At present, the most advanced printing equipment in the world is German-made machinery, among which the famous brands are: Heidelberg, Roland, Gaobao and other manufacturers. The printing equipment produced in Germany is simple to operate and has precise control of coloring. Now in the packaging and printing industry, the equipment of these brands is also the most used. The printing process of transparent packaging boxes is also very complicated, which is the precise control of color. There are tens of millions of colors, and the same ink can produce hundreds of dark or light colors. Therefore, in the early stage of printing, the correct understanding of color will directly lead to whether the color matching in the later stage can be in place.

The printing production of plastic boxes is a systematic project. From the color design of the file to the plate making and then to the subsequent printing on the machine, the coordination of each link can produce packaging products with accurate colors.
