The color matching light box is usually a combination of multiple light sources. For example, it can provide simulated daylight D65, D75, D50 and simulate the lighting of showrooms, TL84, CWF, U30, as well as home lighting F, INCA, horizontal daylight, ultraviolet lamps, etc. These light sources must be recognized by large international organizations, such as store light recognized by Wal-Mart, daylight recognized by international testing agencies, and various special requirements specified by customers.
The most commonly used are these six light sources D65, TL84, CWF, F/A, UV, U30.
The color matching cabinet is widely used in textiles, plastics, paints, inks, printing and dyeing, pigments, packaging, ceramics, leather, cosmetics, etc. The multi-light switch makes it easier for you to detect whether the sample has metamerism (referring to The color of the sample matches under one light source, but when turned to another light source, it does not match). The ultraviolet light is added into the color light box to make sure the closest natural daylight. The ultraviolet light can be used independently or together with other light sources to detect the fluorescent whitening agent on products, dyes and coatings.
