Color difference exists in all walks of life, such as textile printing and dyeing, plastic electronics, cosmetics, leather, beverages and food, medical samples, etc. However, in the field of printing and packaging, when we design a product packaging or need to print some materials, especially when there are multiple colors and patterns, color difference is inevitable. Let's take a look at the printing and packaging aspects. How can we avoid serious color difference? Let's take a look at this question.

1. Use the correct color mode
On the display, the RGB color mode is brighter than the CMYK color mode. In the printing field, the CMYK color mode is more in line with the actual printing manuscript. In addition, the total value of the CMYK four colors of the printing manuscript shall not exceed 250% (the color value is greater than 250, which is heavy black, affecting the printing effect).

2. Choose the right printing equipment, method, material, proofing
To avoid color difference problems, you first need to choose the right printing equipment and materials. Use special printing, and the color deviation range error is relatively small. In addition, you must also know the impact of different materials on color. If you have strict requirements on color in the early stage of design, or want to see the color and effect, you can choose to print digital samples.

3. Precisely control the ink formula
Ink is one of the key factors that determine the color of printed packaging. In order to avoid color difference problems, printing manufacturers need to accurately control the ink formula. By adjusting the proportion and concentration of various pigments in the ink, more accurate color output can be achieved. In addition, customers can also provide standard color samples, and printing manufacturers match the actual color according to the customer sample color to ensure that the color of each batch of production is not much different.

4. Strictly control the printing environment
The printing environment also plays a vital role in avoiding color difference problems in printed packaging. Factors such as temperature, humidity, and lighting will affect the printing effect. In order to avoid deviations caused by subjectivity, professional instruments can also be used to make faster and better judgments through instrument assistance. Therefore, these environmental parameters need to be strictly controlled during the printing process to ensure that each batch of production can obtain the same printing effect.

5. Conduct strict quality inspection
Quality inspection is an indispensable step to avoid color difference problems in printed packaging. During the production process, the quality of printed products should be monitored at any time, and parameters should be adjusted in time to ensure consistency. At the same time, a comprehensive inspection should be carried out before the final product leaves the factory to eliminate any factors that may cause color difference problems.

6. Work with the supply chain to jointly solve problems
The color difference problem of printing and packaging is not only the responsibility of the printing manufacturer, but also requires joint efforts in every link of the supply chain. Close cooperation between brand owners, designers, printing manufacturers and raw material suppliers can improve the transparency and efficiency of the entire production process, thereby better avoiding color difference problems.

In actual production, due to limited conditions, we cannot completely eliminate color errors. Therefore, we can only be familiar with the color problems caused by various reasons, standardize operations, formulate standards, strengthen quality control in each link, and improve the color management of the system, so that the color quality difference of the product is controlled within the specified color difference standard.
