Commonly used light sources for textile fabrics

Textile fabrics go through many processes in the production process. In this process, due to raw materials, production processes, manipulations and other errors caused by various reasons, often different batches, even the same batch of fabrics will be different in color. The size of the fabric color difference, if the color light source is different, the color environment, the color of the different time, the evaluation of the color difference is also different. Therefore, in order to correctly evaluate the difference of colors and ensure the consistency of the results of color matching, in the visual assessment of color, the color matching of the light source specified by the merchant must be selected in the standard color light box, so as to avoid visually caused by non-standard light sources or different light sources. The difference. Common standard light sources are:

D65 - international standard artificial sunlight (evening north window light), most customers use it to the color TL84 - three-color fluorescent lamps, European and Japanese store lighting, European and Japanese customers usually use CWF - cold white light, the United States Store or office light source, US customers often use this light source UV - UV, used to detect brighteners on fabrics or fluorescent dye A - Sunset light source, reference light source In order to make the right color results, in In the standard color light box, the observation area at the time of color matching cannot have direct light from the outside, so as to avoid the visual disturbance of the external light.

With the standard color light box in a variety of light sources can also verify the "color different spectrum" fabric, that is, two colors of fabric matching in a light source, but under another light source there will be significant differences.
