Hi Gerry,
It seems the G7 process is not generating much enthousiam among newspapers
printers worldwide. The latest IFRA contest is still conducted on the base
of ISO-12647-3 conditions.
Thoughts?

The G7 process would an ideal way to to set up your
web presses with FM
screening. A profile can be created from an IT8 chart after printing within
the G7 process. This method is based on gray balance and tone shape. The color
of the newspaper stock is factored in by a formula applied to the tone curve.
The primaries and secondaries of solid ink would be standard newprint values.
The G7 method will be particularly helpful in managing the FM screening on
newsprint.
The entire method is explained in the "How to" document available has a free
download from
www.gracol.org. Please review the pdf document for all tools
needed to complete the process successfully.

Gerry Gerlach
