Relative colorimetric rendering will map Adobe RGB 255,255,255 to
paper white, and move all the other colors relative to that white.
With absolute colorimetric rendering you might get the measured color
coming out as paper white, but I wouldn't be totally surprised if you
got something else instead.

Afternoon,
Here's a scenario that's been puzzling me for a while. Let's say I
take a spot reading of a sheet of white paper using an Eye-One
spectro using PMP ColorPicker, assuming the Adobe RGB 1998 colour
space, and get roughly:
R: 250
G: 240
B: 215
Not surprisingly, paper isn't neutral, nor is it white. If you
create that "colour" in PS then send it out to the same paper using
a calibrated and profiled setup, you end up with a grey image. I'm
missing something, for sure, cause in my mind, you should get
*nothing* printed as you're printing the paper's colour. Intent is
relative, black point compensation.
Thoughts?
Cheers,
Derek Cooper
