Thanks Tony. Interesting about the canvas. I have an Inkpress sample pack which a local dealer gave me for free so I'll be interested to test it and the mattes.
I was printing some profile test charts last night as well as some grayscale evaluation charts on both Epson Premium Luster and the Inkpress Chrome Luster. The Inkpress paper is noticeably whiter and just a little cooler than the Epson. The brighter white led to a little better definition in the gray step wedge as well as the full tone gradient. I couldn't see marked differences in the color patches of the test charts but I'll be interested to see how the profiles compare.
The dealer that I got the samples from was very enthusiastic about the paper but I don't know how much fine art printing he's doing. he mentioned that they are supposed to have some new media coming out with very impressive gamuts.
I think the paper is worth looking at. I've been curious that I haven 't heard too much about their paper being used by fine art printers who frequent the boards.
BTW, with the roll stock Chrome Luster, I got the best color charts using "Heavyweight Semi Gloss" media type. Slightly better greens and blues than when using "Semi-glossy Photo Paper".
I prefer the Inkpress Waterproof Canvas to the other canvas media from Legion, Epson, Fredrix, etc. Seems to give me better color accuracy, even with custom profiles for other canvas.
