QTR-Quadtone RIP

Hello,

This is my first post.  I recently purchased the Epson R3000 and also installed the latest version of QTR.  Instead of finding profiles for specific Epson papers, the profile names have 'raw' where you would normally expect to see a paper, such as EPremSemiGloss.  What is a 'raw' profile and when should I use it?

Incidentally, I am on a Windows machine (Win 7 64 bit).

Thanks,

David
