Maybe because I liked it so much, but more likely for commercial reasons, Harman FB Al paper seems to be disappearing from distribution.
There is a new line named "Harman by Hahnemühle".
My sample pack arrived yesterday.
The apparent replacement for Gloss FB Al seems to be Gloss Baryta 320 which has a very similar surface but is a bit whiter than the Harman Gloss FB Al
There is also a new Gloss Art Fibre 300.
Its surface has more of an Epson Luster look to it and is a bit less glossy than the Harman FB Al. It also seems a bit whiter and brighter.
Also in the line is a Matt Cotton Smooth, a Matt Cotton Textured (sort of like an Epson Watercolor surface), a Warmtone version of both the Gloss Baryta and Gloss Art Fiber and a Canvas. The Warmtone versions are not as warm as the Harman warm toned paper, so might work a bit better for some.
I will have to buy a roll or two of this stuff and do some printing before I have more of an opinion. At the moment all I can say is that the papers all have a very good feel and the surfaces look very good.
