Greetings,
A printing press is, as Rick McCleary said, a complex process
involving a machine, a person (or several), and a whole system of
process controls.
Nothing stands alone in the process, and nothing can be isolated from
the other parts, as that breaks the chain of complex events that is
printing.
G7 can be one of those process steps, and if used correctly, can
reduce the variability of production that is experienced by most
printers.
Another equally important factor, one that is seldom mentioned, is the
quality and consistency of ink.
If inks are purchased and used without testing for color consistency
and acceptability, then the G7 gray balance will break, and the
process will go out of control.
Many of the best printers hold their ink suppliers accountable for the
color and the make-up of ink. When the acceptability standard is
reached, then the press can run within the tolerances under which G7
balance was achieved.
Many printers also have ink manufacture and quality measurement in-
house, ensuring that they have constant control over that variable.
One could argue that paper, blankets, packing and other parts of the
process are equally important, and they are. It is important to
evaluate as a series of interlocking steps, each of which must be
monitored with care and caution.
The best printers are those whose process is meticulously monitored
and adjusted for consistent quality – every step of the way.
Best wishes,
Brian P. Lawler
