I've been using PrintFab Pro for about a year with a canon iP4700, mostly in CMYK mode, and mostly as a "driver", but occasionally as a RIP. I make my own profiles, and also happen to be in the Colour Management business! Generally I get very good results, and find the basic media settings etc. to be very good, but would like some more adjustment. Is it just this printer? I would like to have a bit more control over grey balance (especially for B&W), ink limits (especially black) BEFORE printing my test charts. I print with Colour Management disabled. Almost all changes I make using Contrast, Individual Color Correction, Ink Control 2, has no effect. Some high quality papers should be able to take more ink. I can control Total Ink and GCR in the profiling software. I used to use GutenPrint, which had unlimited control (too much!) but didn't support Canons.
Thanks in advance,
