Permajet has suprisingly close substitutes of Hahnemuehle papers (I suspect paper base is the same), so Smooth Art Silk 300g/m^2 offers the same specific look.
Interesting, this paper is grouped within the gloss range and says the unlinked areas remain matt.
So close they could be identical :-) It is the only distributor who thought that having a clone of HM Baryta FB 350gsm is a good thing; Permajet Fibre Base Distinction 360gsm. The 10 grams difference must be what Distinction adds.
