1, the instrument type and parameter design of chromatic aberration have great influence. For example, the absolute value of light source selection D65 and F is far from that of a machine. Just like when you look at a color swatch in the sun and under a fluorescent lamp, the color is different.

2. The color difference meter is a very portable and easy-to-use three-color colorimeter, specially designed to measure the color difference between two colors. This table is used to measure non-luminous and non-fluorescent samples, such as textiles, paper, leather, spraying materials, etc. It is a useful tool for quality control and wide industrial application.

3, there will be, different models of equipment from the same manufacturer will also have differences, and different manufacturers will also have them. Some of the differences between different equipment are small, and some are big.

4. However, due to some objective factors, there are deviations in values. Even if the same colorimeter is used to measure the same point, the values measured several times are slightly different.
