Spinning & weaving Color measurement

There are two main types of textile color measurement: visual evaluation and instrument measurement. The former is intuitive, but easily affected by the subjective factors of Testers; the latter is accurate and objective, but sometimes it is difficult to reflect the complex psychological stimulation of color. Therefore, both are indispensable for color difference measurement, but instrument measurement is the main trend. The color difference formulas currently used internationally are:

ANLAB, CIELAB, CMC, JPC79, FMC II formula and Hunter formula, etc.,

Different countries have different usages. Although these color difference formulas have a good correlation with human vision, each formula has some shortcomings more or less. Instrument determination of color difference is widely used, and can be used for sample approval, large sample determination, fastness level evaluation, whiteness measurement, and customer (555 classification) color difference inspection. There is no need to send samples, and the color values and ΔE and LAB values are circulated online, which can shorten the time from sample reception to sample confirmation. In customer inspection, especially the CMC (2:1) color difference formula is more in line with human eye evaluation, and is more popular in the United States and many European countries
