I don't want to seem to be turning this into a blog. I have been using Lightroom for years, but this is the first time I have ever used a printer that uses profiles. And I have discovered that in Lightroom it is possible to soft proof using the paper profiles and get a good idea of what the final product will actually look like.
When I first installed this printer I made several prints of the same image using different profiles, not realizing that I could soft proof with those profiles. Then, through further experimenting, I have gone back and soft proofed the image that I printed using the different paper profiles. Guess what? The soft proof remarkably resembles the prints that I created.
Doing this successfully depends on preparing the image for the specific paper that is going to be used. Then in Lightroom, create a soft proof copy with the adjustments that are necessary to optimize that proof. The soft proof will be created as a virtual copy and will be named with the profile that was used. Then, you can go to the print module and set up a print job that should be exactly what you are expecting. The soft proof copy will not reflect the effects of the profile or any adjustments that you made while soft proofing was enabled. But those adjustments will be applied to the printed image.
This may seem very basic to some of you. That is why I have posted in the beginners forum. But maybe this will help the OP with the original question. If I have misunderstood something, I hope someone will correct me. But I'm amazed at how accurate my prints are matching now.
I've been using the Pro-100 for a few months. It is a great printer that I'm very happy with. There is currently a very aggressive rebate program if anyone wants a new printer. FWIW, I've been unable to find anyone, anywhere not happy with the Canon Pro printers. Basically, you can get $170 worth of paper and ink for $99 with a "free" printer until the end of the year.
Back to the subject!
There are potentially three completely different workflows between Lightroom and the Canon Pro- 1, 10, 100 series that involve selecting papers, ICC profiles and color management.
1. Print with Lightroom controlling the colors. You have to open the printer driver and disable the printer's color management. Selecting the paper in the driver seems to set the profile.
2. Print with the printer managing the colors. In LR you have to select Color Management > Managed by Printer. Then turn the color management in the printer back on through the driver.
3. Print with the Canon supplied plug in. After installing the plug in from the supplied disk, in LR go to File > Plug-in Extras > Canon Print Studio Pro.
As a Lightroom fan, addict and believer in everything J Kost says, I was using #1 and loving it for landscapes. I had to work a little to figure out how to disable the printer's control as J Kost's examples were for Epson. Then I tried to print a portrait of my granddaughter and her cheeks kept getting a little bit purple. When I checked the Print Preview button in the printer driver, I could see the color shift from the LR preview.
I switched to #2 where the printer makes the decisions. The previews matched and the cheeks stopped blushing.
Then I watched a one hour video lecture done by a Canon product specialist on the B&H Photo website. He demoed the Canon Plug-In. I'm strongly considering using that from now on. I hope J Kost won't be upset with me! It appears that the Canon plug-in really does have better quality control over the printing process.
One especially interesting feature in the plug-in is a test sheet that looks like a proof sheet. There are a bunch of thumbnails printed on a single sheet with different color casts and adjustment numbers under them. Once you pick the one that's "right" you can save the setting as a preset for that paper.
Note that in the long video, the Canon rep emphasized the support of 3rd party papers in the plug-in.
The too long video was worth the time investment. I understand my printer and printer more from having watched it. The link: http://www.bhphotovideo.com/indepth/photography/tips-solutions/canon-pixma-professional-inkjet-printers-exactly-you-envisioned
