In industrial production, different batches of the same product often cause color differences between goods due to deviations in materials, ingredients or production processes. Although the quality inspector has carefully compared the colors of the goods, it is difficult to determine the color difference of the goods because the ambient light source is not standard, and the colors seen under different lights are different. When the merchant inspects the goods, he will complain because the color difference exceeds the standard range, and even return the goods. With the standard light source color light box, the color of the verification of the goods is carried out under the same light source and controllable conditions, which effectively solves the problem of color difference caused by the non-standard light source. It is suitable for the color fastness evaluation of textiles, printing and dyeing, printing, plastics, pigments, paints, inks, photography and other industries and the evaluation of the degree of color difference spectrum and the same color. 【Relevant Standards】

FZ/T 01047; BS 950; DIN 96173; ASTM D1729, etc.
