I like Epson Enhanced Matte Paper but I would like a slightly heavier paper with a just noticeable raised grain. I do not want to use a "coated" paper. What should I be looking at?
Not sure what you mean by "coated". All inkjet papers are coated ... without a receptive coating the results would be pretty poor. I don't use matt papers any longer, but from what you describe you may want to look at Epson Exhibition Fiber, Ilford Galerie Gold Fiber Silk, and Hahnemuhlee Fine Art Pearl and Fine Art Baryta. The Epson paper is very flat and feeds through a 3800 quite easily.
