Researchers at Fogra tested a number of different colour-matching strategies. Ten different profile variants were generated and visually assessed under M1 and M2 illumination. The results showed that colorimetry works well. However, colour matching between media, with varying amounts of optical brighteners, requires appropriate perceptually-adapted conversion methods.
