When trying new papers (such as the new PK papers), I've ordered profiles from them. They're a bargain & quite good for such purposes. But when you figure out what paper/ink combination you're really going to stick with, I'd spend the extra $ for a profile from Andrew Rodney. His are made from more color samples & he creates a larger file of corrections. The differences I've observed are in shadow detail & control of Epson driver's smudgy greens.
