@rgb I don't know if I made myself clear... The AdobeRGB space, let's say, is where SLR cameras shoot. They have a sensor that has a wide range.

This space is used in image processing to make sure that colors are not "spoiled" during color correction.

Before printing, the wide range is compressed to CMYK, taking into account the eye's sensitivity to one color or another.

And the same is done every millisecond when the work is displayed on the monitor ;-)
