printing color can be taken on a print control strip of a printed sheet for the ink zone
control. In addition ExPresso Mini provides the opportunity to get an overview of the
stability of the print run, by measuring the last ten printed sheets. Advanced functions

ExPresso Mini can display the last ten mea-
surements per color.
When, after the tenth measurement, the
display is filled up with measurement values,
the already existing values shift with every
new measurement one step to the left, and
the first value falls away.
The reference line marks the average value of
all measurements.
The tolerance area is defined with ± 0.10
density.
The average value is recalculated after every
measurement.
