QTR-Quadtone RIP

Josh,

Thanks to you I finally decided to follow the whole process today. I  
now have an excellent linearized warm curve for the standard UC inks  
on matte paper. Building the final ICC profile was my last step after  
reading your message, and it really came out great.
I'm now trying to create a cool curve, lots of reading ahead I  
guess... ;)

Thanks again for your time and help, much appreciated. And thanks to  
Roy for making available this great soft.
If I manage to build a decent cool curve I'll post it with the warm  
one in the files section, unless new ones have already been built for  
the next version of QTRip.

Best,
Fred
