Online Colour Measurement System

The colorCONTROL ACS 7000 colour measurement system from Micro-Epsilon Eltrotec is used where colour sensor measurements are not accurate enough. The system operates contact-free at distances up to 50 mm with a measuring geometry of 30°/0°. The measuring spot is 9 mm with a measurement accuracy of ΔE < 0.08. The measurement system provides a number of operating modes: users can employ one of several methods to perform simple measurements between colour distance ΔE and the reference value: ΔE_(CMC), ΔE₉₉, ΔE₉₄, ΔEDE₂₀₀₀. For spectral measurements, the user can choose between different colour spaces: L*a*b*₉₉, L*c*h*, L*c*h*₉₉ were added to the conventional XYZ, L*a*b* and L*u*v*. Improved lighting brightness compensation and improved temperature compensation now support spectral measurements for lighting and plasma colours. All modes support measurement speeds up to 2 kHz. colorCONTROL ACS 7000 can be used for both production line measurements (inline) and for laboratory or sample measurements (offline). This measurement system is suitable for automotive paint inspection, interior colour measurements, forensics, foils, injection moulding, wood, veneers, textiles, printing, medical technologies, and coating technology.
