Textile fabrics go through multiple processes during the production process. During this process, due to raw materials, production processes, Errors caused by various reasons such as operation, often different batches or even the same batch of fabrics will have differences in color. The size of the fabric color difference depends on the color light source, color environment, and color time, and the evaluation of the color difference will also be different.
Therefore, in order to accurately evaluate color differences and ensure the consistency of color matching results, when visually evaluating colors, the light source specified by the customer must be selected in the standard color matching light box to avoid color matching caused by non-standard light sources or light sources. The difference results in visual differences.
Commonly used standard light sources are:
International standard artificial daylight (average north window light), most customers use it for coloring
Three primary color fluorescent lamps, European and Japanese store light sources, commonly used by European and Japanese customers
Cool white light, a light source used in American stores or offices. American customers often use this light source
UV Light, used to detect whitening agents or fluorescent dyes on fabrics
Sunset light source, reference light source
In order to make the color matching results more accurate, there should be no direct light from the outside in the observation area when matching colors in a standard color matching light box to avoid visual interference from external light.
