Techkon SpectroDrive Manual page 45

If a color bar is selected, whose ink zone width differs from the ink zone width of the
selected press, a warning is displayed.
If the selected color bar does not contain a paper white patch, a paper white calibration has to
be carried out manually, before the function "Scan color bar length" can be used.
The green arrow located left from "Scan color bar length" indicates that the color bar has to
be measured. By pressing the green measurement button (2. in picture p. 44), SpectroDrive
scans the printing sheet an sets the length of the color bar. The green arrow disappears, if a
color bar length has been scanned and captured successfully.
As a default, the color bar will be centrally aligned. Additionally the ink zone for the first mea-
surement can be defined individually. Use the arrow buttons of the "Starts in ink zone" function
to define which ink zone of the press will correspond with the first zone of the color bar (1.).
The selected connection between the color bar and the ink zones of the printing press is also
shown graphically (2.).
If no color bar has been detected, an information window appears (3.) which reminds the user
to position the color bar accurately (see p. 12 f.) and to repeat the measurement.
If a printing press with a reversing unit has been defined, there will be a measurement section
for the top side as well as one for the reverse side. This provides the possibility to capture two
different color bars for top- and reverse-printing.
