Sigma DS1, DS2, and DS3 Card Printers Installation and Administrator’s Guide 35
Monochrome Ribbon
Monochrome ribbon produces single-color cards. Monochrome ribbon can be
any of the following:
Alternating black and topcoat panels (KT or KTT ribbon)
The printer applies black and one or two topcoat panels on the
same side of the card.
Continuous black (K ribbon)
A continuous color, for example, green or silver (also called a
K ribbon). Refer to“Monochrome Print Ribbon Kits” on
page 51 for a list of available colors.
Ribbon Saver
Continuous monochrome printing with certified ribbon uses the Ribbon Saver feature. With
Ribbon Saver, the printer begins using ribbon at a location that corresponds to the leading edge
of the image on the card. The printer continues to spool ribbon for the length of the image but no
farther. The printer leaves a small margin between each card to avoid image overlap.
Print Text in Monochrome
Printing text using a K panel can make text look crisp, because it uses only one panel for printing.
Fine text is more readable when printed with more power. You set the power for the K panel
using the Printer Dashboard. Refer to the Printer Dashboard Help for more information.
The font used also affects legibility. The printer reliably
prints 4-point Arial font. Bold, sans-serif fonts are
more readable after printing than serif fonts, or fonts
with thin strokes, as shown at right. In the example,
fonts that print well are shown toward the top of the
card.
The Card Printer Driver allows you to specify a custom
print resolution of 300x600 or 300x1200, which also
may increase the legibility of smaller font sizes. Refer
to the XPS Card Printer Driver User’s Guide for more information.
