Which profile are you referring to? There will be no less than three involved in the scenario you describe. I've always found the black point of a monitor to be much darker than any of the devices I've measured. If BPC is on going out to the monitor profile (as is the implicit default in Photoshop - you have to turn "Simulate Black Ink" on to turn BPC off); then the image appears too contrasty, the shadows too deep. The preview is not accurate or representational. If the output profile has a zero black point, well then it's just wrong.

I don't understand, Tom. If "it would not give a good representation of the image" how can it work? Are you describing viewing situations that are not linked to any kind of output? Where the monitor is the final output device - more "pleasing color" situations?
