Abstract
Two types of new on-line color measurement systems were developed for the continuous measurement of the color difference or the whiteness of travelling steel sheets. Applying these systems to a production line of colored galvanized steel sheets, it was found that the color difference measured by them coincided well with those obtained by a tristimulus colorimeter.
