CMS, ICC, CMM, Device Integration

但是 CMS 这种东西.. Linux 下面,可能吗。

看的是 DesktopColorPhotoPrintingExample.pdf 文件。就 Printing in Color Communication 而言,那句 “Predict color: create device spedific color, and device simuation” 简直是充满了想象力,让人觉得 Apple 的 ColorSync 太完美了 :p

另一句话是 “ICC Profiles: Describe how to transform colors between device color space and interchange space (PCS, Profile Connection Space)”,然后下一页说,“CMMs: Provide the mathematical engine to perform color transformations”

..假设要在目的设备中使用源设备中不存在的颜色,以得到更好的表现力,岂不是会失真了(比如说,和屏幕不一致)?然后按照 Color Communication,在输出之前就可以根据 ICC Profile,再次转换回屏幕显示,前后两张屏幕图片会不会差别很大呢。不过那才是真正的打印预览,我想。

颜色单位相同的时候,比如都是 RGB,还需要颜色转换吗?
PCS 有多少种?
