I'm happy with the profile I made for my Epson paper, but ironically the one I made for the Canon Photo Paper Plus (and my Canon printer!) looks and measures a bit blue in the neutral tones. I'd like to try using I1Profiler's optimization features, but I'm not sure in this case what the best approach would be. Do I print out a grayscale image and use the import funtion? Do I use one of the other techniques?
