Digital BW, The Print

As I mentioned, if you are willing to order from the US you can buy the 325
and 205gsm weights double sided in sheet sizes from 8.5" to 17" wide as well
as the others in rolls from Photowarehouse - it's the cheapest source (the
manufacturer...).  And also the 250gsm + the other two weights in rolls -
there is also a 500gsm weight they don't list.

They will also cut the paper to different sizes for you (at a cost)

Their paper may be 99% the same as Epson Ultrasmooth (possibly the identical
paper). Inkjetart also sells it both as the Premier Art and their own
Digital Museum paper
