Color printing post-press surface treatment techniques

Color printing is developing better and better in the domestic market, and the color printing market in foreign countries is also very good! With the development of color printing industry, color printing post-press surface treatment is becoming more and more important in packaging production. The success or failure of the current color printing market competition depends largely on the packaging of the goods, and the quality of the surface treatment of the color printing goods after printing determines the quality of the packaging material market. Therefore, we can say that post-press surface treatment is an important technical means to improve the packaging grade and strengthen the competitiveness of the commodity market.
