Evaluate whether the packaging box is qualified from the aspects of color, production, and technical requirements. In the printing process of packaging boxes, color consistency and saturation are the main factors that make up qualified packaging boxes. Guide you on how to reduce color deviation in packaging box printing.
1. Before production, it is necessary to confirm the text and determine the color value of the sample. However, the samples of the printing box are different after all. To catch up with the sample color with the printing color, it is necessary to constantly adjust the color during printing. However, due to issues such as paper, ink, and mechanical pressure, there may be some errors between the printed product and the sample
2. The printing quantity is also related to color difference. If the quantity is small, the ink color will be uneven, the pressure will not be high, and there will be color deviation.
3. After coating, the color will also change. The coating is a water-based or oil-based film, and the printing color will deteriorate and produce color difference when it comes into contact with the printing surface.
During the printing process of the packaging box, it cannot be guaranteed that the sample is consistent with the printed product, and can only be as close as possible. Communicate with customers before printing, acceptable within a reasonable margin of error.
