Mark, I am very much looking forward to your review!
My settings form Canson Prestige:
Drying Time per Print Head Pass: 5
Paper Thickness: 8
Platen Gap: Wide
I found Prestige to be just a very smidgen brighter that Photographique, with very slightly more saturated blues and blue-violets. I can see that because my photography is abstract, of light shining through dichroic filters, prisms, so I do get very highly saturated non-landscapey colors.
I do like the paper, though, it feels good in the hand, and the surface is more upscale, so to say, than CIBP.
I did make a huge mistake though, and I hope others don't emulate this - I could only find 11x17 sheets, so for testing I cut say 10 sheets in half to play with the resulting 8.5 x 11. I did use fresh x-acto blades, but still, never realized how messy it is to cut through Barium Sulphate :-)
