Abstract
AbstractIn order to test the performances of different color matching functions (CMFs), a total of 80 pairs of neutral metamerism printed samples based on five lightness levels were prepared. 26 observers with normal color vision were organized to carry out the visual experiments with the gray scale method. Four CMFs, including CIE1964, CIE2006, Sarkar 2 and BIGC 17 were compared with the calculated color difference (∆E) and the visual color differences (∆V) by the Standardized Residual Sum of Squares (STRESS) values. The results indicated that amongst the four CMFs, Sarkar 2 with the smallest STRESS value of 26.8 and the maximum number (equal to 46) of observers from 52 judgements, it’s outperformed others and secondly by BIGC17 CMFs. CIE recommended CMFs, CIE1964 and CIE2006 have no advantages over Sarkar 2 and BIGC17 CMFs when viewing printed materials illuminated by the fluorescent light sources in the field size larger than 10°.KeywordsColor matching functionsGray scale methodMetamerism neutral printed samples STRESS
