QTR-Quadtone RIP

The Eboni-6 inks are a little warmer in the 1.5 pl printers.  However, I've
found that with appropriate profiling I've been able to hold the Lab B of
Premier Art Smooth BW down to Lab B = 1.  So, I assume that could also be
done on the 1800.  

 

Carbon-6 is not recommended for the 1800 due to its surfactant (Photo Flo)
being too weak.  However, stronger surfactants take care of that banding
problem.  Eboni-6 has a good one that works well with the 1.5 pl printers.

Thanks Paul. I recall you saying that you don't suggest the EB6 inks
for the R1800 in here somewhere. Why is that?
