Taking the guesswork out of colour control


the guesswork out of colour control on board, paper and tissue products -- from whites and pastels to dark shades – to help reduce variability, dye usage and costly rejects associated with off-shade production. The latest generation offers

new features that improve overall quality and enable faster colour matching, making it easier for operators at all levels to meet specifications. The system uses ABB’s


High-Performance Color Measurement – the first LED-based continuous colour


ABB’s Color Control stabilises sheet colour faster by using control algorithms


ew features in ABB’s Color Control for QCS800xA are said to take


measurement device on the market – and combines it with the fastest Multivariable


Color Control to establish full shade property insight and traceability. It stabilises


sheet colour faster by using control algorithms, based on advanced models rooted in the Kubelka-Munk theory of paper colouring. “Our latest innovation in


colour measurement and control capability allows mills to benefit from a robust and smart system that delivers the best colour in all operating conditions,” says Carl-Magnus Tjeder, global product manager at ABB. “Because it only requires one calibration for each dye, which is integrated into the dye management handling system, it also places fewer demands on operators to intervene manually, leaving more time for other, more pressing tasks.”
