Unless something has changed, I would not use Cathy's Profiles....period!
A bunch of people have sent money and printouts over the past year, and received nothing in return, and no answers to e-mail.
When I first started using the Canson version of this paper for my 3800, I made a profile and tested it against theirs. I guess it doesn't say much for my knowledge, or equipment/software, but theirs was a better profile than mine.
