Whether the packaging box is qualified, from the color, production, technical requirements of these aspects to evaluate. In the packaging box printing process, color consistency, saturation is the main factor of qualified packaging box. Take you to understand how to reduce the color difference in packaging box printing.

1. Samples are required to confirm the text and determine the color value before production. However, the samples of the printing box are different after all. If the printing color is used to catch up with the sample color, the color needs to be adjusted continuously during printing. However, due to problems such as paper, ink, mechanical pressure, etc., the printed matter and the samples have certain errors.

2. The number of prints is also related to the color difference. If the number is small, the ink color is uneven, the pressure is not large, and the color will also deviate.

3. The color will also change after the coating. The coating film is a water-based or oily film, and the printing color will deteriorate after contact with the printing surface, resulting in color difference.

The packaging box printing process can not guarantee that the sample is consistent with the printed product, only as close as possible. Communication with customers before printing is acceptable within a reasonable margin of error.
