QTR-Quadtone RIP

I would like to use this ink (why let it not be used?) since I feel 
using the larger number of inks might make a better tone.

Ken, you don't need LK to produce good QTR curve with UT7. This set was 
designed for printer driver, which uses LK, but when you mix inks in 
QTR, it is hard to linearize with this ink. This is why there is no 
curve that uses this ink. I am using light light gray instead.

Good luck,
Sergei
