QTR-Quadtone RIP

Hi all,

I managed to find myself a cheap (ok free...) R200 and have purchased 
MIS's UT2 inks for it.  I've experimented with Paul's workflow using 
the Epson driver and am so far impressed.  However...I'm still curious 
how QTR would compare.  Given this, I've got two questions:

1) Does a QTR curve for the R200 using UT2 exist?  If so, how could I 
get a copy of it?
2) In other people's experiences, how does QTR compare with Paul's 
workflow using the Epson driver in general?

Thanks all,

Cheers,

Mark
