The Slickrock papers were released after the iPFx100 series printers were discontinued, so we rely on customers who are using the machines to print the profiling targets and send them to us to create the profile. I would be happy to create a custom profile for you, please email evan at legion paper dot com for the instructions. I wouldn't recommend using the Slickrock Pearl profile on the Silver paper, as they have a different base color and gamut.
