Precision measurement is what separates a colour-house from a colour-laboratory. Spectrophotometry, when paired with a tight feedback loop, drives Delta-E values below 0.5 across continents and batch numbers.
What Spectrophotometry Measures
A modern spectrophotometer captures the reflectance of every wavelength between 360 and 750 nm. The data forms a fingerprint of the pigment’s behaviour under daylight, fluorescent, and tungsten illuminants — three observers, one tone.
Closing the Loop Between Lab and Plant
By streaming live readings from the production line back to the QC console, our chemists can adjust press-cake density and dispersion shear in real time. The result: a batch acceptance rate above 99.4% on the first sample.
