Kurt,
The printers won't stock the fine art brands (Canson, Harman, Moab, Hahnemuhle, etc) in their drivers. These you would need to get from the manufacturer directly, download it and have Canon's MCT (Media Configuration Tool) install the profiles to your computer. If you want to do it yourself, you're more than welcome, but the MCT will install drivers with a click of a button for you. Canon will only provide their product profiles when you install the drivers (same with Epson and HP with their drivers). This process will also be the same with Breathing Color, Atlex (Simply Elegant line), LexJet (Sunset line), etc. since these are house brand products.
You would either acquire these fine art or house brand profiles and install them to match the colors properly, or use a the match thru Canon's drivers.
Hope this helps.
