颜色管理中的白场适应问题(英文)

White Point Adaptation Issues in Colour Management

在某种媒介上再现源自于另一种媒介的颜色时(比如印刷再现显示图像),最常用的方法是将源媒介的白场与目标媒介的白场相匹配。但是这种方法仔在一定的局限。本研究通过一系列的实验,获取了一些心理物理学的数据,以便更清楚地认识颜色管理中的白场适应问题,开发更有效的颜色管理解决方案。在此基础上,评价了在采用白场补偿的条件下,不同承印物上印刷输出匹配的可接受性,并测定了承印物色差对此匹配的影响程度。

When reproducing colour from one medium to another （ such as display image reproduced in print）, the most com- mon strategy is to map the white point of the source medium to the white point of the destination. But this approach is limit- ed by several factors. In this study, a series of experiments was being performed to provide some psychophysical data that can contribute to understanding of white point adaption issues in colour management, and to the development of appropriate colour management solutions. The acceptability of hard copy matches on different substrates, with white point compensation applied, was evaluated and the magnitude of substrate colour difference producing acceptable matches was determined.
