Spectrophotometer Calibration and Inter-Instrument Agreement
topic
Spectrophotometer calibration uses standard white ceramic tiles and grey scale tiles traceable to national measurement institutes for wavelength and photometric scale validation, while inter-instrument agreement assessment compares CIELAB coordinate measurements of ceramic, glass, and fabric reference standards between multiple instruments to quantify systematic between-instrument colour offsets affecting supply chain colour communication.
Role
Ensures that colour measurements from spectrophotometers in supplier, brand, and retailer laboratories are comparable and that colour approval decisions made on measurements from different instruments are equivalent, addressing the inter-instrument colour measurement variation that is a primary source of colour dispute and rework in complex multi-site textile supply chains.
