QTR-Quadtone RIP

To John and Nemo (previous message)

I have only used the "better" choice under the "High Speed" setting. I also thought to try all 
the dither patterns. I printed each one out on the 21 step scale and saw weird patterns 
somewhere in the scale with all of the patterns except the standard: ordered, so I've stuck 
with that. 

As it happens, I was in Vermont the week *before* I loaded this machine with K6 inks. I 
had been shipped a mislabeled cart so I took it with me and the Cone folks were able to 
exchange it for me on the spot. The densities I see on an inkseparation chart match what I 
expect, but is the ink somehow bad (ie the density looks right but the ink doesn't perform 
correctly??)

What seems to be having a positive effect is making my own profiles. I've found I can up 
the overall ink limit beyond the 50% that comes with the supplied profiles. But now I 
wonder, do I set individual limits for each ink? For instance, black maxes out around 65%- 
cyan can go to 80- the others seem to continue to gain desnsity right up to the 100% area, 
should I go with such a mismash of limits? I've tried making a profile like this and it's 
working pretty well, but needs more tuning. Am I heading down a path here that will be 
filled with frustrations and blind alleys?

Thanks for your help

Mark
