The color of the laboratory is different. Is there any difference between the morning sunlight and the afternoon sunlight? For printing and dyeing factories, choosing the source of light is a very important thing!
Standard light source operating parameters
The standard light source color-matched light box is usually a combination of multiple light sources. It helps users provide simulated sunlight D65, D50, simulated shop showroom lighting TL84, CWF, U30, and home lighting F, INCA, horizontal sunlight HORIZON, For ultraviolet lamps, UV, etc., the corresponding parameters of each light source are not the same.

A light source: The color temperature is 2845K, which is equivalent to the light radiated by the incandescent lamp at 2800K.
Light source B: The correlated color temperature is 4800K, which is equivalent to direct sunlight at noon.
C light source: The correlated color temperature is 6700K, which is equivalent to the natural light during the day, and it has more blue components.
D65 light source: The correlated color temperature is 6500K, which is equivalent to the average daylight. In recent years, it is often used as a standard light source for color TVs.
E light source: also known as isoenergetic white light, that is, P(l)=constant. It is a hypothetical light source that does not actually exist. It is used purely to simplify calculations in chromatics, and its correlated color temperature is 5500K.
F series illuminants represent various types of fluorescent lighting.

The color is usually observed in daylight, so the fine color discrimination in industrial production requires that the lighting source must have a spectral power distribution that approximates real daylight, that is, the D65 standard light source specified by CIE, and the D65 standard light source light box is also a large market demand. A color light box.
