3.8.2 RFID Media Guideline for Alpha-40L(R)
Here are a few things to consider for optimum performance. (Referring to the diagram on the right)
IMPORTANT: Always test RFID media on your printer before purchasing large quantities of media.
◼ Inlays should be centered across the media width with
a production tolerance of less than +/- 2mm
(dimension "a"). Consistent, tag-to-tag placement of
the inlays is more important than how close to center
the inlays are actually placed.
◼ Only Direct thermal media are supported. Minimum
black bar size is 8 mm(w) x 2 mm(h) and position is
centered.
◼ Maximum roll OD is 62 mm (2.44”). Media should be
wound on 1”, 0.75” or 1.5” ID core.
◼ The pitch (overall distance from inlay to inlay) is shown
as dimension "P". Tags with pitch less than 1" may
require the printer to back-feed during the encoding
and printing process, thus slowing the throughput of
the printer. The pitch should be greater than 1", if
possible to avoid this condition.
◼ The inlay should be set back from the lead edge of the
media (dimension "X") a constant distance tag to tag.
The "X" distance should be more than 5 mm to prevent
pre-peel.
