Thanks Scott for bringing up the color calibration importance of the x400 Canon printers. Fortunately, I did color calibrate my Canon ipf6400 this weekend, before I printed my targets from my new Xrite i1 photo pro. Yes, I turned off color management, definitely always do that.
I also calibrated my smaller Canon Pro-1. They come with their own software to do this also -requiring the i1 or colormunki, and ran some targets on it also.
I am glad to know how important that is, I was not sure and I figured that if Canon included it, I was gonna use it. Yes the unique and common calibration distinctions are strange, but I studied the manual and think I have a small handle on Canon's procedure and was successful on both of my Canons.
Thank you, Debra
