Various types of colorimeter applications. Maybe most people don't know much about color difference meters. I don't think that color difference meters are used in general life. In fact, color difference meters are not widely used in various industries, such as plastic electronics, paint and ink, textile and garment printing, and printing paper , Food, medicine, cosmetics, optical image debugging and other industries, the principle of color difference meter debugging is mainly based on the CIE color space Lab, Lch principle, the measurement shows the sample and measured sample color difference △ E and △ Lab values. In simple terms, it is not of great practical significance to judge a certain color based on a set of Lab values, but when people compare two colors, people can judge them by the Lab difference of the two colors. The difference between. In addition, two sets of Lab values can be used to calculate the color difference between two colors. If the color difference is greater than 1, people's eyes can distinguish it. Therefore, people can set a certain tolerance range in advance. When performing quality control, the color difference between the measured sample and the standard color is a qualified product within the tolerance range, and an out of range is an unqualified product. Through the use of Lab color space, people's production control has been digitized.

Colorimeter

Various types of colorimeter applications. The color difference meters currently on the market can be divided into three types according to the appearance and shape: 1. Hand-held color difference meters-can directly read the color difference data, generally cannot be connected to a computer, without software. Easy to use and cheap, but with lower accuracy. It is widely used in the general field of color management. 2, portable colorimeter-also known as portable spectrophotometer, can directly read data, can also be connected to a computer, with software. Small size, easy to carry, high accuracy and moderate price. 3. Desktop color difference meter-also known as desktop spectrophotometer color matching meter, generally without reading display, color measurement and color matching software is used when connected to a computer, with high-precision color measurement and color matching functions, large size, stable performance, and price high.

Various types of colorimeter applications. At present, domestic color difference meters may still have many technologies that are inferior to foreign products, but I believe that one day people will catch up with and surpass foreign products, just like the microwave ovens of that year, people ’s brands will be crowded out. Foreign brands occupy the domestic market. The color difference meter's market and prospects have great potential!
