摘要
彩色复制品中,颜色复制的准确与否是一个很重要的衡量与评价因素。设计灰梯尺作为视觉评价的标准进行主观评价,选用颜色复制中常见的9个匀色色块,分别改变明度、饱和度与原色块比较,进行主观评价。分析主观评价数据与测量数据(ΔEa*b*、ΔE2000),不同的颜色区域的匀色色块对明度、饱和度的响应不同,不同的色差公式测量的结果也有很大的区别。
The veracity of color reproduction is an important weighing and evaluation factor. Gray scale was designed as the standard for subjective evaluation, in which nine typical color patches were selected including changing lightness and chroma independently to compare with the original for subjective evaluation, The data from subjective evaluation and measurement （ AEa ＊ b ＊ ,AE2000 ） was analyzed, It was found that different colors have different responses to lightness and chroma, and different color difference formulae have different results.
