Colour Measurement Science and Colorimetry
category
Colour measurement science in textiles applies CIE colorimetry, spectrophotometric instrumentation, colour difference formulae, and visual assessment correlation methods to objectively quantify, specify, and communicate the colour of dyed and printed textiles in a manner that predicts visual colour perception and enables instrumental colour matching, quality grading, and process control.
Role
Provides the scientific and metrological foundation for objective colour communication, recipe prediction, quality control, and commercial colour specification in textile dyeing and printing, replacing subjective visual judgment with quantitative colorimetric data that enables global supply chain colour consistency management and reduces costly colour approval iterations.
