Interesting. Do you use a special profile just for soft proofing, or is this how you run your setup at all times? If the former, do you have a simple way of switching back and forth? I find that the settings I have work well when I generate output for online viewing, so switching to 85 cd/m2 would probably make the pictures I post online too dark. Is 85 cd/m2 a generally accepted brightness for printing?
