Thanks, Roy. I copied the Purge K curve over to the 3880 folder. The initial results were way too dark and I got an error message stating that I didn't have ten inks. So I opened the curve file in "notepad" and removed all references to Orange and Green and resaved. That seemed to do it. Added my same minor gamma tweeks and the print looks good, and life is looking good, again :-)Thanks for a great program.
