What are the details that need to be paid attention to in color management of self-adhesive coated p

In the color management of self-adhesive coated paper labels, the following details need to be paid attention to:

First, clear product color standards

Formulate reasonable color upper and lower limits: Before the production of each label product, clear the upper limit, standard and lower limit of product color according to customer needs and industry standards. This step is essential for subsequent color management.

Keep and refer to the proof: for the first production, the proof should be made and kept, and the color standard should be confirmed by the customer. Subsequent production will be based on the standard color of the sample to ensure the consistency of the color.

2. Strictly implement the inspection system

The first and last part signing system: the inspection items of the color of the label products are included in the first and last part signing system to ensure that the production management personnel can effectively control the color differences of the label products.

Strengthen inspection and random inspection: In the process of printing and production, by strengthening inspection and random inspection, timely discovery and treatment of label products beyond the reasonable range of color difference.

3. Use standard lighting sources

Select the right light source: printing workshop and quality inspection area should use printing standard lighting source, conditional enterprises should be equipped with standard light source box, in order to allow employees to label products under the standard light source color contrast.

Avoid light source differences: Pay attention to avoid differences in color evaluation under different light sources, and ensure that the light source is stable and standard at any time when the color inspection is carried out.

Fourth, the selection of appropriate printing materials

High-quality ink selection: Use inks produced by regular manufacturers, pay attention to the shelf life of the ink, and update the inventory in time to avoid using expired ink to reduce the risk of color change.

Paper quality control: The selection of stable quality coated paper, considering its absorption, whiteness and other factors on the impact of printing color, to ensure the accuracy of printing color.

5. Equipment calibration and maintenance

Regular calibration of equipment: Different printing equipment can produce color offset and color distortion problems, so it is necessary to perform regular equipment calibration to ensure that the color produced by the printing is consistent with the expected color.

Equipment maintenance: Regular maintenance and maintenance of printing equipment to ensure that the equipment is in the best working condition to reduce the impact of equipment factors on color accuracy.

In summary, in the color management of self-adhesive coated paper labels, it is necessary to pay attention to the details of clarifying product color standards, strictly implementing the inspection system, using standard lighting sources, selecting suitable printing materials, and carrying out equipment calibration and maintenance. Together, these measures ensure the accuracy and consistency of label printing color.
