How to detect the same color as the customer’s requirements of brand tag-A

In the brand label (Brand Tag) production process, to ensure that the label color and customer requirements are consistent is critical, which is directly related to the brand image and product quality. The following will be from the testing equipment, testing process, quality control and problem solving, etc., a detailed introduction to how to detect the brand label color is consistent with customer requirements.

First, the detection equipment
Spectrophotometer
Principle: Spectrophotometer through the measurement of the spectral properties of the object reflection or transmission, can accurately analyze the color of the numerical data, such as chromaticity coordinates (Lab * value), color difference (ΔE) and so on.
Applications: The spectrophotometer is the equipment of choice in brand label color inspection. It allows non-contact measurement of label samples, avoiding damage to the sample while providing highly accurate color data.
Color Difference Meter
Principle: The colorimeter is a portable color measurement tool that is based on the principle of the spectrophotometer, but is much lighter and easier to use. The colorimeter can quickly measure the color difference value between the sample color and the standard color.
Application: On the production line, the colorimeter can be used to monitor the label color in real time, to detect and correct color deviation in time.
Standard Light Box
Principle: The standard light source box provides a variety of standard light source environments, such as D65 (simulated daylight), TL84 (simulated store lighting), etc., for observing and comparing colors under different light sources.
Application: In brand label color inspection, the standard light source box can help inspectors simulate the actual use of the environment, observe the color performance of the label under different light sources to ensure color consistency.

Second,inspection process
Obtain customer standards
Customers usually provide color samples (e.g., color cards, color samples, etc.) or color values (e.g., Pantone color numbers, Lab* values, etc.) as color standards.
The inspector needs to carefully check the color standard provided by the customer to ensure accurate understanding.
Making standard samples
According to the color standard provided by the customer, use the same material and process as the production to make a standard sample.
The standard sample should be used as a benchmark for subsequent tests to ensure that all tests are conducted under the same standard.
Measurement and Recording
Measure the label samples using a spectrophotometer or colorimeter and record the color data (e.g. Lab* value, color difference ΔE, etc.).
At the same time, observe the color performance of the label sample under a standard light source box and record the observation.
Comparison and Judgment
Compare the measured color data with the color standard provided by the customer and calculate the color difference value.
According to the size of the color difference value and the customer’s requirements, judge whether the label color is qualified or not. Usually, the smaller the color difference value, the closer the color is to the standard.
