Delta E Color Measurement

Delta E color measurement is a numerical method for expressing the visual color difference between a target and a production sample, typically using L*a*b* coordinates from a spectrophotometer. In cosmetic packaging, it helps brands and suppliers evaluate batch consistency across glass, coatings, print, and component finishes when the substrate, opacity, gloss, or texture can shift appearance. Meaningful measurement depends on agreed illuminants, observer angles, sample preparation, instrument settings, and acceptance tolerances. Delta E does not replace overall sample approval or compliance review; it supports decisions about color match and variation. Buyers should define what constitutes an acceptable difference for each material and finish, then use physical references and controlled measurements together to judge production lots.
