Color measurement system of colorimeter

We know that each instrument has a corresponding system, and the colorimeter is no exception. The color measurement system of the colorimeter is also known as the color system or color system, which is actually the way people organize and express colors. In general Chinese literature, it is customary to call “color system” the color system. Up to now, there are mainly 2 methods for color representation of color difference meter, one is “color model”, the other is “cataloging system”.

Color model is a set of rules and definitions that describe all colors in a simple way in the development and use of color difference instrument. Among them, color space is the most common example of color models. We often say that CIE LAB, CIE XYZ, RGB and CMYK are color models. The cataloging system assigns a unique name or number to each color. Such as Munsell color system, Pantone color card, etc.

However, in the color difference instrument industry, the use of Munsell color system is higher. The Munsell system divides the three-dimensional color space into three axes: hue, brightness and chroma. This system is very powerful in terms of order, but it does not provide the coordinate system needed for color space description of the colorimeter. Based on this disadvantage, the CIE color system developed by colorimeters converts any spectral curve into three letters, which become trichromatic values X, Y, Z. When Y is associated with light, X and Z are independent of hue and chromaticity.

Chromatometer CIE 1976 LAB chromaticity space
CIE1976LAB color space is usually called CIE LAB in the color difference instrument industry. It is also called CIE L * a * b * in many colorimetric literatures. CIE LAB is currently the international color measurement standard and the most widely used chromaticity space in the color industry. This color space uses coordinates to mark chromaticity values, which is called chromaticity coordinates. The idea of using color coordinates comes from the fact that colors are not both red and green or both blue and yellow, but colors can be considered as combinations of red and yellow, red and blue, and green and blue.

Application of colorimeter in cosmetics industry
The pursuit of beauty of human beings will not change with time. Now the pursuit of life is reflected in all aspects, and the most common is the “practical art” of make-up. Based on this, the cosmetics industry is very competitive. In order to meet the requirements of customers, it can be more intelligent. The color of cosmetics is one of its intuitive and important evaluation criteria. Therefore, the application of color difference meter in this industry is not unexpected. The colorimeter provides fast, accurate and high-end solutions for controlling color quality. In order to develop a visual feature that is different from other products in the highly competitive cosmetics industry, and to be more attractive to consumers, color design and application are not required. The color circle has summarized the “seven second law”, that is, consumers will decide their purchase intention within seven seconds. Therefore, it is important to control the appearance and color of the product within 7 seconds.

The early rising cosmetics industry is not well prepared for the problems facing the color age, and has suffered a lot in color management. It can be said that many companies should restrict their development for the bottleneck problem of color management. But now the color detection and control equipment and software are very complete. The color control, determination and assurance of color uniformity among batches in cosmetics will no longer consume a lot of manpower, material resources and time as before. The cosmetics on the market are emerging in endlessly, no matter in shape, form or type. For solid, powder, paste, liquid, etc., if you want to use the same color difference meter to measure, it has put forward very important requirements in terms of technology and function. We know that there are many small parts inside the precision instrument, such as colorimeter, which are wet and may cause damage to internal parts. Therefore, paste objects and liquids cannot be directly measured. In addition, the powder shape is irregular, and some cosmetics solids will also fade and pollute the caliber. Therefore, there are many details and methods to be paid attention to when measuring cosmetics.

Most cosmetic colors are generated by reflection of light, such as eye shadow, lipstick, nail polish, etc. When the white light shines on the product surface, the pigment in the cosmetics will absorb the color light of the corresponding wavelength in the white light and emit the remaining color light. When the remaining color light enters the eyes, it will stimulate the corresponding visual nerve, and we will produce the corresponding color sense. For the detection of such products, the reflection measurement position of the spectrophotometer shall be selected for detection. During measurement, the light from the light source of the instrument is scattered by the integrating sphere for many times and then shines on the surface of the tested sample. The light reflected from the surface of the sample is received by the receiver of the instrument, which generates the corresponding optical signal and converts it into an electrical signal, which is processed by the computer to obtain color data.
