QTR-Quadtone RIP

I normally use the enhanced matte curves and like them a lot but I 
can't help but notice there are a lot of other papers and inksets 
listed in the dialog box.  Is there a list somewhere that explains the 
abreviations listed?  I would like to try some of the others but I 
don't want to waste paper doing so.

Thanks for any help you can give.
Randy
