ABB Color Control is a powerful tool for paper mills that make colored products – ranging from whites and pastels to all kinds of dark shades – to help reduce color variability, dye usage and costly rejects associated with off-shade production.
The system stabilizes sheet color faster by using multivariable control algorithms, based on advanced models rooted in the Kubelka-Munk theory of paper coloring. Color Control is designed to utilize the full power of our unique High-Performance Color Measurement
, which uses a continuous LED light source and high-speed spectrometer for faster and more reliable color, brightness, opacity and whiteness measurement.
The accuracy of the measurements coupled with our advanced Color Control enables papermakers to automatically and precisely achieve the target shade, reducing off-spec product, and shade change and start-up times.
