摘　　要：为了在实际生产过程中针对不同类型原稿及其用途快速准确地选择相应的色域映射意图,详细研究了常用的4种色域映射意图对不同类型原稿的影响适应性,即哪种色域映射意图能够使特定的原稿准确再现。实验选择具有代表性的图像和TC9.18RGB色表分别按照4种色域映射方式输出,运用视觉主观评价和色表测量数据的客观评价方法相结合归纳出4种色域映射的适应性。实验结果表明,注重色调和层次上表现的原稿类型适合采用感知映射,注重色彩渲染的原稿类型则适合采用饱和度映射,而对于精确再现的图像则适合采用绝对色度映射。To choose the appropriate render intent quickly and accurately for different image types with specific uses in the actual production process, the adaptation of four render intents was studied, that is, which kind of render intent can accuratly reproduce the special original image. In the experiment, the Representative images and Tcg. 18 color spar was chosen and output with the four render intents separately, the adaptation of four render intents was generalized using visual subjective evaluation and objective color evaluation with measurement spar datas. The exprement results showed that the original images that focus on the hue and tone level are suitable for perceptual intent, which focus on the color rendering are suitable for saturation intent, and which are for the accurate reproduction are suitable for absolute colorimetric intent, The research results has an important significance on the actual printing process.
