One small element seems to be missing from the picture, however ;
what to do
with process control.
Figuring out what to do with the black is straightforward and is
achieved
with a good old densitometer. But figuring out what to do with CMY
proves to
be a challenge. Really. Having adopted the nominal a* and b*
defaults of 0
and -2 for Gray Tone Aims, printer X now wonders how to instruct its
pressmen to control gray balance on press the way they used to do
it, very
successfully, with simultaneous measurements on the red, green and
blue
StatusT filters? Nothing in the G7 documentation seems to covers
this part
of the G7 method.
Will printer X have to buy 528s for all its presses, all of a sudden?
Nah. Just measure the density of the gray and review the response of
all 3 filters. They should be within about .03 of one another (or
close to what you achieved on your test runs).
