And pay for a full press run of targets... or live with the reduced accuracy
of trim area profiling...
Before you decide on a strategy, you have to know the variables. It
makes no sense to run a testchart in the trim area unless you know
the ink zones are calibrated and stay calibrated across the format.
Down the sheet the deltaE may be less than 1. Across the sheet the
deltaE may be very high in which case the profile doesn't match the
press condition.
If you have a system that controls the graybalance across the format
of the press, and based on that you run testcharts in waste areas of
the sheet, then that's another issue.
