Hey RK,
Ok it wasn't the Epson site it was actually the Brilliant Paper site that had this great walk through setup for using Photoshop and Epson Printers.
Go to
http://www.brilliantpaper.com/brilliantdigital.html
once the page loads in the left hand margin you'll see some links to pdf's select your version of Photoshop and make sure you get the one one for the PC platform.
Just ignore that the references to the brilliant profiles and use your own for whatever specific paper you are using.
I hope this helps.
Cris...
