For your information:

A friend told me about Epson Exhibition Fiber paper and since it was on sale at Atlex (no longer on. line), I bought a box to try. Unfortunately, I just assumed that Epson would have a profile for using this paper with my Epson R1900 printer.

They don’t. But I went ahead anyway and got pretty good results with it by printing with the Premium Photo Paper Semi-Gloss profile.  YMMV.
