My test image
In the last 4 days I have printed 26 test images on 23 papers on the Epson 2200. Outcomes: I like the look of optical brighteners (non-archival), smoother texture, and icc profiles make a HUGE diffference. Favorites right now: Moab Entrada and Hahnemuhle Photo Rag for the matte papers.
The glossies are still drying.
Epson's Enhanced Matte is what I've used up until now. The Somerset Photo Enhanced Velvet didn't get a fair shake with a proper icc profile (their own fault for making it so hard to find one). I have not tried Epson's own Watercolor Radiant White. All the matte papers are pretty fragile, will require matting to ship.
