I have another round of G7 calibration coming and, for sure I will create
two sets of curves, of for AM and another for FM. But even, as Mike and
Terry indicated, I'm hitting the same or very close NDPC, the pressmen will
tell me that FM consume less ink than AM. I tend to go along the explanation
of Mike as to why that it. But it is a fascinating "paradox" nevertheless.
Imagine GCR on top of FM screening: soon we'll be printing with no ink!
