Sažetak

Input devices in general use light sources with different color temperatures. As a consequence, in color acquisition, display and rendering processes a number of chromatic adaptations transforms (cats) are being used. In our study, color transformations between three illuminant source pairs (d50-a, d50-d65 and d65-a) were investigated using five cats (Bradford, von Kries, xyz Scaling, cmccat97 and cmccat00). Research was made on 8190 color patches that were printed with inkjet printer. Results showed that color differences obtained with the Bradford method were the lowest regardless of the implemented illuminant source pair. The same ranking of cats was observed in all combination of illuminant source pairs, however the smallest color differences were generated with d50-d65 cats and the biggest with d65-a models.
