Color difference meter function introduction features and methods
Colorimeter
The colorimeter is widely used in the plastics and printing industries. It mainly displays the color difference â–³E and â–³Lab value of the sample and the sample to be tested according to the Lab and Lch principle of the CIE color space.
main feature
1. Automatically compare the color difference between the sample and the tested product, output CIE_Lab three sets of data and colorimetric data of â–³E, â–³L, â–³a, â–³b after the colorimetric, and provide a reference scheme for color matching.
2, with sample and single measurement mode, to meet the needs of different places measurement, simple operation, accurate measurement.
3. The instrument is portable. There are two power supply modes, battery and external power supply, which are convenient and practical.
?
4, installed with the USB expansion interface, you can connect to the computer display.
5, clear, accurate backlight LCD display.
6. The LCD screen can be selected from 6 languages ​​including English and Japanese.
7, can be driven by a rechargeable battery, economical and practical.
8. Measurements can be taken separately using the measuring head. The measuring head can be removed from the data processor and measured separately using the measuring head.
9. Any evaluation formula and color calculation formula can be freely set.
10, built-in high-speed printer miniaturized data processor data processor
Instructions
This paper introduces the color difference measurement process by taking the color spectrum CS-200 as an example. The three colors in the following figures are the standard sample, the No. 1 test sample, the No. 2 test sample, and the color difference between the No. 1 test sample and the No. 2 test sample and the standard sample.
First measure the standard sample
Boot, enter the interface;
Black calibration first, then white calibration;
sample
Finally enter the rapid measurement, press the test button to make the standard sample measurement, and get the results shown in Figure 2;
Standard sample color measurement
This sample was transferred as a standard sample.
Measuring the color difference of test sample No. 1
Place the instrument on the No. 1 test sample.
According to test, the results are shown in the figure below;
Since the standard sample is very close to the color of the No. 1 test sample, the measured color difference is only 0.09.
Measuring the color difference of test sample No. 2
Place the instrument on test sample No. 2;
According to test, the results are shown in the figure below;
The color difference from the standard sample is 52.83, and the test sample No. 2 is darker and redder than the standard.
