Besides being a color detector, portable spectrophotometer is also your color data management expert. With the portable spectrophotometer, you can save all the colors of your products. You can take the portable spectrophotometer out and call it at any time, which is very convenient. Let's take a look at how to manage color data in the flag industry.

Flag, banner, also known as "flag". It generally refers to the cloth hanging on the pole with specific color and pattern. The "flag" of the flag refers to the cloth strip with equal columns of horizontal lines, which is the national symbol of the ancient Fangguo. The above pattern is symbolic and used to convey information or classification. Today, most flags (as shown in Figure 1) have been used as national symbols, sometimes for publicity or pure decoration.

A flag factory in Fuzhou specializes in silk screen printing color flags, knife flags, red cloth strips, digital color flags, gradient flags, ribbons, armbands, brocade flags, etc. Different colors on the flag represent different meanings, so the accurate silk screen printing of the flag color is very important.

Determine the color of the printed flag through the CMYK value. First, proofing the colors of different CMYK (as shown in Figure 2), compare the Pantone color card to be printed with the sample, find the CMYK corresponding to the similar color, and finally input the CMYK value into the computer for color matching printing.

The cmky values of different materials (as shown in Figure 3) are different even if their colors are the same. Therefore, samples of different CMYK shall be made for each material.

Figure 3 cmky values of different materials are different

At present, human eyes are used to identify which color is similar to the Pantone color card, but this method has great errors, and each color comparison also takes a lot of time.

So the factory found Hangzhou CHNSpec technology, a high-tech enterprise focusing on optical, color and other photoelectric testing technology. The company recommended the CS-660a Pantone version of the machine (as shown in Figure 4) to the other party and provided corresponding solutions.

The solutions are as follows:

1、 Proofing the colors of different CMYK;
2、 Use CS-660a Pantone spectrophotometer to measure and save each sample, and establish a color library;
3、 Measure the target color. The instrument compares the target color with the color in the color library, and selects three colors with similar colors. Each color represents a CMYK value;
4、 Input the CMYK value into the computer for printing. Compare the three printed colors with the target color to determine the final CMYK value for production and processing.

Specific steps:

1. Create color library
Samples with fixed materials shall be used to sample the colors of different CMYK, and the color of each sample shall be measured and saved. Press the "print" key, first locate the measurement area with the image, then press the "test" key, and then complete the measurement after "dripping" sound, and view the test results.

In the title bar of the test results, the first column is the name of the standard sample, which can be saved by pressing the "save" key. Save each sample according to the above steps and complete the establishment of color library.
2. Color lookup
For the new sample or Pantone color card, measure the target color with the instrument, and the instrument can automatically display three CMYK values with similar colors.

By adopting the scheme of portable spectrophotometer, the time-consuming and laborious color finding of the manufacturer is solved. At the same time, the control of flag color difference has also been improved. The portable spectrophotometer has greatly improved the production efficiency and printing quality. With the high-end color measurement technology of CHNSpec technology, portable spectrophotometer and extensive technical support network, it provides customers with excellent color management system and powerful pigment color matching database to help customers realize integrated operation from R & D standards, digital process operation to individual supplier evaluation.
