You are missing the point of Dale's original comment: "you need to convert the device colors through device independent color space like XYZ,CIELAB,CIELUV". But that is clearly not true! It is a lot more convenient to convert to a device independent colour space and from there to whatever output medium you want to use because the number of profiles need for N different image sources and M destinations is limited to N+M colour profiles. But you could with a *lot* more work compute direct colour profiles for every possible combination of source and destination N*M. In the early days when N was about 3 and M was about 4 that was what happened. It may still make a lot more sense to store the original image in the colour space where it was measured and only ever compute the device independent form as a hidden step on the way to the output device. What do you do years later, when all information about the creating device's characteristics are long gone, and all you have is an image file? You know about embedded profiles, right? BugBear |
