the current ICC profile connection space is an ideal print, or maybe an

for transparent display, translucent display, motion picture display and
other additive systems like CRTs LCDs etc. this means you have to create
information to render the ideal print to these spaces

wouldn't it be better too have an ideal additive system as the profile
connection space and compress the tone and color the data for prints, as
opposed to creating information for additive systems

probably would lead to more precise capture rendering too

I beg your pardon, but one of the choices for the profile connection
space is XYZ which is a perfectly linear, additive system.

isn't this the XYZ relative to an ideal print? I'm pretty sure it is.
There is also the difference between color matching and appearance
matching. Appearance matching can be image dependent so you would have
to use some kind of scene balance algorithm, SBA , which doesn't quite
work for professional images and is best left to the image
editor/artist. SBA can prove good enough for most consumer images.
