He says that matte papers have less dynamic range, less contrast, and a smaller apparent color gamut than the more glossy papers. Mike Chaney, who I believe wrote the Qimage program, published an article called Using Matte, Semi Gloss, and Gloss Papers. I do not see these large out-of-gamut warnings when I select the glossy profiles (Pro, glossy, semi-gloss, ect.). These warnings cover much more of the images when I select the matte papers (matte, fine art photo rag, other fine art paper selections in the profiles) than if I used even the i860 printer matte profile. I have no complaint about the quality of the prints so far except that I am concerned that this out-of-gamut warning indicates a much smaller gamut than I was expecting. They have to call me back after checking with their engineers. I have asked Canon tech support about this because the out-of-gamut warnings with this matte paper on the MP990 might exceed 65% or more, even on a portrait. However, I often use Matte Photo Paper, and I find that in Photoshop CS3 with the gamut warning on, there are far more out of gamut colors with the MP990 than with the MP960 or the Canon i860 (only cyan, black, magenta, yellow, and pigment black inks) on the same photo using this Matte paper. It may be that the Canon profile for the paper I am using is just better than the profile for the same Canon paper for the other printer. The MP990 printer does seem to match my calibrated monitor much better than the MP960. That unit used photo cyan, photo magenta, cyan, yellow, black, and pigment black inks. It is replacing a dead Canon MP960 multifunction unit. First of all, I have only printed a few photos because I just got the printer. I have an issue with the Canon MP990 printer, which has cyan, yellow, magenta, black, gray, and pigment black inks.

I hope it is okay to start a new thread with this issue even though I put it in another thread earlier that had a different issue with the MP990 printer.
