Epson now has "ULTRA Premium Glossy Photo Paper" that is even smoother
than EPG. So far I have only seen it in 4x6 size. Works well with my
R800 with Gloss Optimizer. Specs show 11.8 mil thickness vs. 10.4 mil
of regular Premium Glossy, Brightness 96 ISO vs. 92 ISO and weight 79
lb. vs. 68 lb. Images seem to pop a bit more with this paper than with
Premium Glossy. Bought it at the local CompUSA.
