*edit*
oops, didn't see your post about the 30 hour disc. That's too bad. But I will say that we warned you that inkjet prints would most likely smudge, regardless of whether the media was "printable" or not. Sure, if it were regular media, the ink wouldn't hold at all. But this media holds some, and I think that's the most you can hope for, but it would be more than that faint layer you described.

Your only recourse will likely be as these people suggest, to find a way to print with less ink. Maybe call up Epson and see what suggestions they have?
