Colour Measurement and Shade Control Systems
topic
Inline spectrophotometric colour measurement systems scan dyed or printed fabric surfaces at production speed using LED or xenon light sources with spectral measurement from 400 to 700 nanometres, computing CIE L*a*b* colour coordinates and deltaE colour difference from target specification in real time, with closed-loop shade control adjusting dye concentration, wet pickup, or curing conditions to maintain delta E below 0.5 CIELAB units throughout production runs.
Role
Enables continuous colour conformance monitoring and automatic shade correction during dyeing and printing production that reduces shade variation within production lots and between repeat orders, with inline colour management being the most impactful quality improvement available for dyeing and printing operations where shade deviation is the primary cause of product rejection, reprocessing cost, and customer complaints in colour-critical textile production.
