The metachromatic spectrum (expressed as a flashing light).which is often said in the printing and dyeing industry. refers to the fact that when two colors are observed by a standard observer and under a specific light source (the CWF light source is often used in the US market).the colors match. Changed this particular light source (with D65, A light source as a secondary light source).the color will no longer match.
Two color samples (one standard and one sample).under a certain light source (such as D65).appear to be equal color (no color difference or small color difference).and under another light source (such as A).there is a comparison. Large color difference.we call it the "metachromatic" phenomenon.
The reasons for the "extra spectrum" are
1.The pigment composition of the dyeing is different.
2.Different processing methods
Different dyes will cause jump lights.the dyes used by the guest's small sample cloth and the dyes used in the dyeing factory to produce large goods are different. Although the ingredients are similar. dispersed. active and Shilin. but the dye manufacturers are different. the dyeing factory The color of the hit is definitely not the same, although the dyeing factory is proofing according to the sample color.
Gray is easier to jump, so be sure to use the light source color by D65.TL84, etc.
