Card Printing Basics
The ribbon synchronizes to it’s “starting” position whenever the Main Cover is opened and
then closed. For a
YMCKK ribbon, the starting position is with the leading edge of a Black
Panel at the Printhead location.
The figure below shows how the YMCKK ribbon and card move relative to each other
during printing.
In addition, the driver software allows the user to specify which ribbon panels are printed on
either side of the card.
