ribbon Ribbon is a thin film that is coated on one side with wax, resin, or wax resin (usually called “ink”),
which is transferred to the media during the thermal transfer process. Ink is transferred onto the media
when heated by the small elements within the printhead.
Ribbon is only used with the thermal transfer print method. Direct thermal media does not use ribbon.
When ribbon is used, it must be as wide as or wider than the media being used. If the ribbon is narrower
than the media, areas of the printhead are unprotected and subject to premature wear. Zebra ribbons have
a coating on the back that protects the printhead from wear.
ribbon wrinkle A wrinkling of the ribbon caused by improper alignment or improper printhead pressure.
This wrinkle can cause voids in the print and/or the used ribbon to rewind unevenly. This condition should
be corrected by performing adjustment procedures.
roll media Media that comes supplied rolled onto a core
(usually cardboard). It can be continuous (no separations
between labels) or non-contionous (some type of
separation between labels).
Contrast this with fanfold media.
supplies A general term for media and ribbon.
symbology The term generally used when referring to a barcode.
tag stock A type of media having no adhesive backing but featuring a hole or notch by which the tag can
be hung on something. Tags are usually made of cardboard or other durable material and are typically
perforated between tags. Tag stock can come on rolls or in a fanfold stack. See gap/notch media.
tear-off A mode of operation in which the user tears the label or tag stock away from the remaining media
by hand.
thermal transfer A printing method in which the printhead presses an ink or resin coated ribbon against
the media. Heating the printhead elements causes the ink or resin to transfer onto the media. By
selectively heating the printhead elements as the media and ribbon move past, an image is printed onto
the media. Contrast this with direct thermal.
void A space on which printing should have occurred, but did not due to an error condition such as
wrinkled ribbon or faulty print elements. A void can cause a printed barcode symbol to be read incorrectly
or not at all.
