QTR-Quadtone RIP

Paul,

Thanks for clearing that up. I really like the option of going with  
the Eboni-6 for my R1800. However, I do have a few questions on that  
(sorry I am asking so many!).

1) Is it easy to profile these inks? I don't  have any sort of  
calibration unit. The only thing I have is a scanner. I plan to use  
rag based papers or maybe Barayta style papers (if they will work with  
this ink).

2) I see the eboni-6 uses 6 inks. What position would I put everything  
in on my R1800? What about the 2 extra's left? Do I just put blanks  
carts in there, or will I need something to stop it from drying out  
the heads of the printer?

Thanks,
Shane Jordan
