Hi everyone,
First off, thanks so much for taking a moment to read and help.
My wife and I run a small photography studio, and we use a Canon ipf6100 printer. Recently, we discovered that several shades of purple are no longer printing properly. Very light hues seem fine, but deeper shades (such as a royal purple) come out looking almost like a desaturated blue. No other colors are affected, and (to the best of my knowledge) no profiles or settings have been changed. I've tried several cleanings, replaced the print head, and have messed around with several other icc profiles, but nothing seems to work. I've even went back to test other photos that we've previously printed successfully, but they also lose their purples. Now we have a wedding shoot to print where the bridal party wore (of course) purple dresses, and I have no idea what to try next.
If anyone has any suggestions, or (assuming it's a profile issue) a custom profile that might help the problem, I'd be eternally grateful for the help.
Thanks in advance!
