介质相对颜色匹配中的白点适应研究

White Point Adaptation in Media Relative Color Matching

在不同介质或媒体之间进行颜色复制时,一般方法是将源介质的白点匹配到目标介质白点。由于人眼视觉并非对源和目标观察环境中的介质白点完全适应,因此该方法还存在一定的局限性。通过基于成对比较法的心理物理学实验,验证了介质相对颜色匹配中存在的白点适应问题,评价了在应用白点补偿的条件下,在不同颜色纸张上进行打印颜色匹配的可接受性,并测定了纸白之间色差对颜色匹配的影响程度。研究有助于研发更为有效的颜色管理解决方案。

When reproducing color between the two different medium, the most common strategy is to match the white point of the source medium to that of the destination. Because the human visual adaptation to the white point of the source and destination observing environment is incomplete, so the method has certain limitation. White point adapta- tion in media relative matching was verified using paired-comparison psychophysieal experiment. The acceptability of printing color matches on different color papers under white point compensation was evaluated, The effect of paper color difference on acceptable color matches was determined. The purpose was to provide basics forr more effective color man- agemcnt scheme.
