Colorimetry is a tool used to predict whether two stimulus color samples with different spectral power distributions have the same color under specific observation conditions. Its ultimate goal is to establish a prediction model that conforms to the color vision discrimination characteristics. This article introduces the concept of colorimetry and the CIE standard colorimetry system. Interested friends can learn more!

How to distinguish between cold light source and thermal light source? The so-called cold light source is a light source excited by chemical energy, electrical energy, and biological energy, such as fireflies, etc.; the so-called thermal light source is a light source excited by thermal energy, such as incandescent lamps, etc. So, is the standard light source a cold light source or a thermal light source? The following will answer your questions.

Aluminum foil, also known as fake silver foil, is a hot stamping material that is directly rolled into thin sheets of metal aluminum. Due to its excellent properties, it is widely used in food, beverages, cigarettes, etc., and is usually used as their packaging material. Gloss is an important indicator for testing the appearance quality of aluminum foil, so its gloss needs to be quantified. This article introduces the gloss measurement method of aluminum foil.

Cotton grading is an important part of cotton quality evaluation. However, in the process of cotton grading, the unstable light source environment can easily lead to deviations in grading results. In order to unify the light source environment for cotton grading, there are regulations on the light source for cotton grading. So, what light source is used for cotton grading? This article introduces the light source and lamp models for cotton grading.

When the paint on the car surface ages, peels off or is damaged, the car needs to be repainted. In the process of repainting, the influence of various factors can easily lead to inconsistent colors after paint application. In order to detect the consistency of the color of car paint, a multi-angle colorimeter can be used. This article introduces the method of measuring the color difference of car paint with a multi-angle colorimeter.
