How to avoid self-adhesive label coated paper printing color change

In order to avoid color changes in the printing of self-adhesive label coated paper, the following measures can be taken:

First, establish a reasonable color management system

Clear the upper and lower limits of product color, and in production on the basis of the standard color of the sample, to ensure that the fluctuation of color does not exceed the specified range.

Improve the first and last part sample signing, inspection and sampling inspection system, timely find and deal with color differences, to ensure the consistency of product color.

Two, the use of printing standard lighting source

The use of printing standard lighting source for lighting, conditional enterprises can be equipped with a standard light source box to ensure that employees in the standard light source color contrast, to avoid the problem of print color difference caused by non-standard light sources.

Third, pay attention to the choice and use of ink

Use inks produced by regular manufacturers, pay attention to the shelf life of the ink, update the inventory in time, and avoid using expired inks, because expired inks can easily lead to the fading of label products.

In the printing production process, pay attention to the amount of ink additives used, excessive use may lead to ink color changes after printing. Therefore, when using various ink additives, it is best to communicate with the ink supplier to determine the correct proportion range of additives.

4. Choose the right paper

Choose a paper with moderate surface smoothness, low absorption and permeability to reduce the impact of paper properties on printing color.

5. Control environmental factors in the printing process

Maintain the stability of the printing environment, including temperature, humidity, etc., to reduce the impact of environmental factors on the printing color.

6. Regular maintenance and calibration of printing equipment

Regular maintenance and calibration of the printing equipment to ensure that the equipment is in the best condition to improve the stability and consistency of the printing color.

In summary, by establishing a reasonable color management system, using standard lighting sources, paying attention to the selection and use of ink, choosing the right paper, controlling environmental factors in the printing process, and regularly maintaining and calibrating printing equipment, we can effectively avoid changes in the printing color of self-adhesive label coated paper.
