摘　　要：本文将印刷品观测光源信息引入印刷色彩管理流程,通过获取观测光源的相对光谱功率分布,采用不同光源下颜色光谱反射率转换的计算方法,在不同观测光源下分别计算印刷和打样输出标准色靶色块的可见光谱的光谱反射率,生成观测光源下的印刷设备ICC特性文件和打样设备ICC特性文件。采用两种ICC特性文件分别输出样张,在不同的观测光源下,达到打样样张与印刷样张在颜色视觉上的最佳匹配。In this paper, the observation illumination was introduced into the printing color management process, through access to the observation illumination relative spectral power distribution, using the color spectral reflectance conversion calculation methods under the different illuminations, the spectral reflectance of the standard test color charts from the printing and proofing output devices was calculated. Then, ICC profiles of the proofing device and the printing equipment under the different illuminations were generated. Follow the ICC profiles, the proofs and prints were put out and achieved the best color matching under the different observation illuminations.
