Paper Abstract

A harmonisation process co-ordinated by the National Physical Laboratory (NPL) was set up to reduce errors in color measurements with a target such that 95% of the results should agree to within 0.5 CIELAB color difference units (ΔE*ab). Nine laboratories took part in the harmonisation; some were national laboratories and the rest commercial organizations. The techniques for determining and correcting errors in color measurements are described. Thirteen sources of error were identified, ten of which were corrected for. Although not all the possible errors for the measurement of color have been addressed 94% of the measurements agreed to within 0.5 ΔE*ab.
