Thanks Fred, Claude, and BruceT.

All of your explanations have helped clarify this process for me. It can certainly be confusing with so many places to apply settings.

Merry Christmas!

Thank you for the replies.

I know which profiles were installed with the printer software, and I know which ones apply to each kind of paper (glossy, matte, semiglossy etc). What I was asking (amongst other things) was whether I needed to choose, under "Prtr ICC", the profile for the type of paper I was using, or if when I selected that paper in the printer dialog box, the correct profile was automatically chosen. I suspect that when I choose the media type in the printer dialog box (Photo Paper Pro, Photo Paper Plus Glossy II, Pro Platiinum, etc), the appropriate profile is chosen. If I had also loaded the profile in the "Prtr ICC" then I would in effect be double profiling - am I correct in that analysis?

If I understand you correctly Fred, you are saying that I should choose, in the "Prtr ICC" the appropriate Canon profile for the paper that I am using. Then I should choose "Manual" under "Colour/intensity", followed by "None" under "Colour correction". Is that right? As an alternative, I can choose "Let printer/driver manage colour" under "Prtr ICC", then "Manual" under "Colour/intensity", followed by "ICM"  under "Colour correction". I did a test print with the latter settings and the print looked good. The former settings should produce a very similar print, I assume.

Hopefully I understand the situation now. I appreciate the responses.

Merry Christmas

This will no doubt seem like a very simple question with an obvious answer, and if so, my apologies.
I have just bought a new Canon MX922 printer as well as Qimage Ultimate; I used to use Qimage Studio with other printers, and was happy with the quality of the prints I made. Here is my quandary - I am not sure if I need to choose a profile appropriate to the Canon paper I use, or if in fact the profile is automatically chosen when I select the type of paper in the printer dialog box. In other words, if I choose to print on Canon Pro Platinum paper, do I need to also choose the correct profile, or is that taken care of for me by the printer when I select the type of paper?
As a secondary question, in the "Prtr ICC" section, do I choose "Let the printer/driver manage colour" or should I choose "OFF" (assuming that I am not choosing a printer profile here)? I have found that the colours have been off in some prints (reds come out as magenta) and I suspect that I may have double profiled somehow.
With my previous printer, I had a custom profile made, but I have not yet had that done for my new printer. With the custom profile, it was quite straightforward, but I seem to be having some issues with the new printer.
To further confuse matters, in the printer dialog box, for Colour/Intensity, I can choose Auto or Manual - which is correct? If I choose Manual, another dialog box opens where under Matching/Colour correction I can choose Driver matching, ICM, or None. The Canon help screen for this section is not much help - which should I choose if I have selected Manual?
Sorry that this became longer than I expected. I would appreciate some guidance. I really don't want to use lots of ink and paper experimenting and I know there's lots of expertise in this forum.
