Fogra Roses - Developing a colour difference dataset for the graphic arts

摘要

A new colour difference dataset has been developed to address the specific needs of the graphic arts industry. An experiment has been designed with 1288 colour pairs. Concretely 46 colour centres of the Fogra media wedge and 28 randomly intra- and supra threshold test colours around each of them have been observed by 32 observers. The pair comparison constant stimuli method has been used by means of three grey reference pairs comprising colour differences of AL=1, 3 and 5. The performance of established and modern colour difference formulae has been evaluated with the new dataset. DIN99o and CIEDE2000 outperformed the other tested metrics.
