8.3.2.3.3. Example: Determining the Switching Threshold for a Label Material
After selecting the
panel function Sync.Sens.Level
the contrast of
the inserted material (placed in the photoelectric sensor area) is shown
on the printer display.
The
left level value
is the
currently measured sensor value
(You’ll find more details in the previous sections.)
For
all
different
contrast zones
of the current
material
sensor values
(level values in %) have to be measured now.
Place
the material
in the
photoelectric
sensor
area and read the level values.
Example:
Self-adhesive material with black bars across the label
Zone of the inserted material: Sensor
measured
value (level):
Label + liner + black bar 75 %
Label + liner 44 %
Liner
(other names: carrier or backing)
12 %
Calculation of the Switching Threshold
The
middle between the label level
(incl. liner)
and liner level
has to
be calculated:
(44% - 12%)/2 + 12% = 28%
In this example the switching threshold is to be set to the value 28 %.
(The steps to set the Sync sensor level at the printer panel can be found
on the following page.)
