The role of color difference meter in color management of packaging printing

In packaging printing, color management is crucial in packaging printing. It helps maintain brand image, attract consumers, control quality, ensure color accuracy, improve production efficiency, and coordinate all aspects of the supply chain. Color management work must not be without the use of color difference meter, that color difference meter in packaging and printing can play what role?

1. Color measurement and analysis: DS-220 color difference meter can accurately measure the color of packaging printed matter and provide numerical representation of color. It is capable of analyzing the Lab* value, RGB value, or other parameters of the color space to help determine the accurate characteristics of the color.

2. Color comparison and matching: By comparing the measured color with the standard color, the DS-220 color difference meter can assess how well the print matches the intended color. It can provide a color difference value (Delta E), indicating the degree of color difference, to help determine whether the quality standard is met.

3. Quality control: In the process of packaging printing, DS-200 color difference meter can monitor the consistency of color in real time. It can detect the color difference between prints produced in different batches, different presses or different times to ensure the color quality of the product is stable.

4. Color adjustment and calibration: According to the color data provided by the color difference meter, the operator can adjust and calibrate the color. It can help optimize factors such as ink ratio, printing pressure, paper selection in the printing process to achieve more accurate color reproduction.

5. Supply chain color management: In the packaging and printing supply chain, different suppliers may be involved in materials, printing and processing. The DS-220 colorimeter ensures color consistency across all links, reducing color issues due to supply chain differences.

6. Quick decision and communication: The color difference meter provides objective color data and measurement results, which can help decision makers make quick judgments about color quality. It also facilitates effective communication with customers, designers and suppliers, ensuring that color requirements are accurately understood and met.

When using the DS-220 color difference meter for color measurement, in addition to seeing whether there is a color difference between the measured color and the standard color, it can also provide guidance on color bias, which is very useful to help customers better color mixing.

The color deviation guide in the measurement results of the DS-220 color difference meter (as shown in the figure below) means that the instrument can indicate the direction of the difference in color parameters between the measured color and the standard color. Through the measurement of the DS-220 color difference meter, customers can obtain specific information about color bias, such as red, green, yellow, etc.

This color bias guide is very helpful for customers in the color mixing process. It can help customers more accurately understand the gap between the color they are using and the target color, and the direction of adjustments that need to be made. Customers can adjust the amount of pigments, dyes or other toning materials according to the guidance provided by the DS-220 color difference meter to achieve more accurate color matching.

In summary, the color bias guidelines in the results of the DS-220 color difference meter provide customers with valuable information to help them better understand the color differences and adjust the color accordingly to achieve the desired color goals.
