Two-Colour Printing

For printing in a second colour, the DuoPrint is equipped with an additional printing unit.
A = Front printhead
B = Rear printhead
Label Design
When creating a label, it must, in addition to the contents to be printed, also be determined which contents are to be printed in
the second colour, i.e. by the rear printhead.
The procedure depends on the transfer of the label.
NOTICE!
When creating the label, attention must be paid to the correct setting of the label size and slot length. Incorrectly
set values may result in an offset within the print image.
Correcting the Printout
Mechanical tolerances may result in a shift in the printout. These deviations can be corrected temporarily by setting the X and Y
offsets.
The set offset has an effect on both printheads. With the function Printhead 2 Offset the printouts of the front printhead and the
rear printhead can be corrected to each other.
A permanent shift of the printout is possible with the menu Service functions/Zero point adjustment.
Material Loss
As the print images are printed at different positions on the label, a minimal amount of label material is lost when the printing
process has been started. This is unavoidable, since rewinding the label material is not possible for reasons of a safe material
feeding process.
In order to prevent material losses during the ongoing print job, it is checked after each completely finished label printing
process whether there is sufficient print data to print the next label. The furthe rbehaviour can be set in menu Material
savings/Ribbon save mode.

Error Correction

In the event of recoverable errors such as transfer ribbon errors, the printing process can be continued after the error has been
corrected. If the printhead was opened in order to remove the cause then all labels which have not yet been completed are
printed again.
