Robert,
I tried the Epson Pro Glossy (EPG) paper and ran into the same bronzing poblem.  The EPG is almost identical in surface gloss and texture to the Pictorico Premium Photo Glossy paper except that the latter is a brighter white color.  The "bronzing" problem I'm having with both papers (and the other RC papers as well) manifests itself in the midtones as a metallic bronze color reflection when viewed at certain angles to a light source - almost like a hologram effect.  I tried lowering the curve for the light black ink (in the warm profile) and decreasing the light black ink limit, but these changes only moved the bronzing effect up the scale a few steps.  I think I'll wait for the Ultratones and give up trying with the UC inks on RC papers for now.
