Abstract

It has been reported that the colorimetric color match sometimes does not ensure the visual color match between different medias such as a display and a print. One of the reasons is that the color matching functions (CMFs) used in the colorimetric systems (CIE1931 standard observer) do not necessarily represent the observers' CMFs owing to the individual differences. Although we have constructed a device for measuring the individual CMFs, the validity of these measured CMFs has not been fully evaluated. When metameric match is completed by an observer, color difference calculated with his CMFs should be smaller than those calculated with CIE1931 CMFs. In our preliminary experiment, we carried out the color matching experiment between a LCD display and a color chart. Mean color difference (ΔE*ab) calculated with individual CMFs and with CIE1931 were 5.51 and 6.02, respectively. However, the effects of the compensation of individual differences were not so distinct. One of the reasons is that the stimuli used in this experiment had broadband spectral distributions. If we use a stimulus with narrowband spectral distributions, the effects would be further highlighted as the differences in CMFs reveal more clearly. In order to verify this hypothesis, we constructed a stimulus generator with LEDs, and conducted color matching experiments between LED light and a LCD display. In the presentation, we will report our experimental results and effects of compensation of CMFs, which might lead to a “customized” color management system.
