QTR-Quadtone RIP

Sorry Jon, the question was to you and I jumped all over it.
I am curious though, are there formulation issues that may effect
pigment settling in different ink sets?

Also, I forgot to mention to the original poster- standard procedure
here to avoid anything like this is to take the carts out af all the
printers (the OEMs too) every other Monday morning and give them a
little shake. Also, if for some reason a printer has printed no paper
at all in a few weeks for somew reason, I print a few inches of
something, anything, at 40" wide to give the lines a lot of movement
as well, and also move a bit of ink through them. Seriously, I'm
extremely picky about hue subtlety for mono prints, it's never shifted.
