I'm still perplexed on this. I created a new ICC using the RGB-ICC create tool and that new ICC shows up fine. Unfortunately, the ICC is not good and a resulting ramp is awful. I think my error is that my base ramp was made with gamma 2.2 printer settings not "no color management". This also seems to be a new change in CC CS6 - "no color management" is no longer an option. What settings should be used in its place?
