Squid Technology (don't have their website to hand) do a sample pack of 10 A4 sheets. I have used up these on a 2200 with Lyson Photochrome inks. Looks very good but don't really know whether the black in the CIS is a full Photo black but so far the results are good enough to go for a box of A3+. Squid also do the Innova F Gloss but I think I prefer the Hahnemuhle although juding on A4 only is not entirely straightforward.
I'm just wandering what the new Hahnamhule Fine Art Pearl is like on the Epson 2200? I know that the original Ultrachrome inks have a tendency to bronze (and Gloss differential) on anything other than matte/fine art paper so given the cost of the paper and no samples available from the UK retailers I don't wish to fork out a lot of wedge for a box if its not a good match. (£100 per box of 50 A3)
I have recently tried some of the Chau Digital Fibre Based Gloss (Which I think is pretty much the same paper as Innova FBG and Permajet Fibre gloss).
This is a very nice paper and looks great with colour prints on the 2200. However any b&w prints need a coat of Printguard to get rid of the dreaded Ultrachrome bronzing.
