QTR-Quadtone RIP

Hello,
I just got a new Epson R800, and I make a trial to QuadtoneRip. Its the 
first time I'm using it, I have been reading the manual twice, and I 
browsed through the list, but I did not find any answer to my question:
 on page 9 of the manual, it is said that there are a LOT of curves for 
different papers on QTR. However, in my setting, for the R800 printer, 
there is only on set of curves for the EpsonEnhanced paper (mat papers). 
I do not feel strong anouth for now to make my own curves, so is there a 
place where I can download some curves for other papers ? (Moab, 
textured papers, etc... ).
Thanks for any advices, and sorry if it is a silly question.
