Hummm seeing most of epsons inks are water proof once they set (you can go to most stores and see a epson photo in a jar of water I would guess the CD media you pruchased is NOT for ink jet printing, there are 2 kinds of direct printable cd's Thermo and inkjet

Did you purchase thermo by mistake ?

I personal use the much cheaper epson photo stylus 960 and don't have this problem.
