Gloss uniformity is an important image quality attribute for high quality reflective color images. One of the most important gloss uniformity sub-attributes is “differential gloss”. Differential gloss of printed images (of various image content) on substrates of wide ranging gloss values was studied. The preference levels of gloss and differential gloss were obtained for EP prints. A novel method to correlate image content to differential gloss was described. The mapping functions between subjective responses and the objective measurement were obtained and reported in this study.
