I just scanned in a picture with Photoshop CS2 twain. The scanner was set to no color management. Saved in Photoshop CS2 as psd and ICC Profile Adobe RGB (1998).
When I try to print , the colors are wrong compared to what I see on the monitor, but when I go to assign profile and change from working space Adobe RGB(1998) to sRGB IEC61966-2.1 (that was already there), I get an exact match. I would like to avoid this problem.
