Peter,
Note that ICC's Absolute colorimetric is illuminant-relative colorimetry.
So a display's max R=G=B maps to a second display's max R=G=B even if the
color temps of the displays differ, so won't look the same.
This is different from CIE absolute colorimetric, which is truly absolute
(same XYZs), and cannot reasonably be reproduced in print as paper doesn't
have a built-in illuminant. :-)
CIE absolute colorimetric is often used for cinema projectors.
Absolute colorimetric is useful if you're printing something on two
different paper stocks.
If done right, the prints should match under the same (D50 calibration)
light source.
They need not match under D65, though.
Absolute colorimetric isn't adding any value for displays, as they are
their own light source, so illuminant-relative colorimetry becomes
identical to media-relative colorimetry, i.e. relative colorimetric.
You can also use Lab as color space. Beware that Lab is also based on the
D50 illuminant.
Lars
