Color packaging

Color printing packaging is the use of the working principle of the print color reduction, order reduction, texture reduction, clarity reduction. In which neutral gray balance has an important role in color printing packaging. Neutral gray balance can correctly reproduce the original gray, in the process of plate making and printing, neutral gray balance can be used as a measure of color separation plate printing and printing ink ratio of the size of the primary scale to use. At present, the plastic film composite technology is a composite coating process, which is a process that the glue layer is changed into a solid glue film after drying. Compared with the solid polymer extrusion process, with high temperature and high pressure force into the viscous flow evenly on the printed film "wet complex right", is often called insiders dry compound process".
