What is Bar Code Symbology and how does it work?
Symbology is a specific language (made from bars and spaces) that
sends a number to the software through a scanner. A bar code is “read” when
a beam of light from a scanner is passed over the bars/spaces.
What symbology do I need?
Your circulation software determines the bar code symbology you
need. Each software program reads a specific “language.” The
two basic symbologies are Code39 (Code 3 of 9) and Codabar. The third
(and least used) symbology in library applications is Interleaved 2
of 5. If you can’t find your software’s specifications
in your software manual or are unsure, call your software vendor and
ask what symbology your software supports.
What are the differences between digital, laser
and thermal bar codes?
All three bar code label types are acid-free and are chemical-
and UV-resistant. Thermal have a matte finish. Digital and laser are
offered in laminated and non-laminated. All types are available in
singles, doubles or pairs.
- Digital: These labels are the latest in technology and most
durable bar codes available. Imaged on 4-mil 60-lb. white paper
with a 1-mil permanent archival-safe acrylic adhesive. Advantages
include:
100% guaranteed first time read-rate; higher print-contrast ratio
than photocomposed; archival quality; no change in adhesive;
greater abrasion resistance than all other technologies; and
a lower cost
than photocomposed. See
Data2 Digitally-Imaged Bar
Code Labels.
- Laser: These labels are printed on a 24-lb. smudge-proof paper
using a 1200 dpi laser printing system. Available in five background
colors or white.. See Laser-Printed
Bar Codes.
- Thermal: BThese labels are printed on a 2-mil polyester material.
Available with colored text, color stripe or colored eye-readable
digits. See
Thermal-Printed Bar Codes.
Do I Need a Protector?
We recommend using a protector to:
·
Protect non-laminated bar code labels
·
Repel dirt and other damage
·
Keep information readable longer
·
Eliminate lifting and peeling labels
·
Extend the life of labels
Protectors specifically designed for use on bar code labels are
best to use. Generic tape or protectors may lose quality, which
increases the risk of damage to the bar code label. See our complete
selection
of bar code label protectors for a variety of options.
Quality
protectors can extend the life of the bar code if chosen
and applied properly. Protectors will not affect the read, however
you should always test the scan after a protector is
applied
to one or two bar codes to ensure an accurate read.
See Bar Code Label Protectors.
Whatis a scanner and how do I choose one?
A scanner is the vehicle by which the information from your bar
code is decoded and sent to your software package. As with any
product, there are many levels of quality and various styles
on the market. Always purchase the best-quality product that your
budget
allows.
