Code is a high density 2 dimensional matrix style bar
code symbology that can encode up to 3750 characters from
the entire 256 byte ASCII character set. The symbol is
built on a square grid with a bullseye pattern at its
center. Data is encoded in a series of "layers"
that circle around the bullseye pattern. Each additional
layer completely surrounds the previous layer thus causing
the symbol to grow in size as more data is encoded yet
the symbol remains square. Aztec's primary features include:
a wide range of sizes allowing both small and large messages
to be encoded, orientation independent scanning and a
user selectable error correction mechanism.
smallest element in an Aztec symbol is called a "module"
(i.e. a square dot). The module size and the amount of
error correction are the only "dimensions" that
can be specified for an Aztec symbol and both are user
selectable. It is recommended that the module size should
range between 15 to 30 mils in order to be readable by
most of the scanners that are currently available.
overall size of an Aztec symbol is dependent on the module
size, the total amount of encoded data and also on the
level of error correction capacity chosen by the user.
The smallest Aztec symbol is 15 modules square and can
encode up to 14 digits with 40% error correction. The
largest symbol is 151 modules square and can encode 3000
characters or 3750 numeric digits with 25% error correction.
JETEC for printing 2D codes on your products.
Corporation has the capability of upgrading your present
marking process to include 2D code marking and reading.
For those customers with existing ink jet or laser marking
systems our IMS5000
Software can provide the necessary 2D code marking capability
without requiring additional marking equipment. Otherwise,
JETEC can provide complete, turnkey 2D code marking
systems. All of the marking systems offered by JETEC
Corporation provide the capability to print traditional
1D bar codes as well as 2D codes. JETEC marking
systems incorporate industrial ink jet, laser scribing
and dot peening technologies for Direct Product Marking
(DPM), thereby creating a permanent robust mark without
the expense and hassle of labels. Additionally, all 2D
codes require a 2D code reader for encoding; they cannot
be read using an ordinary linear bar code scanner. Process
engineers should be aware that there is a large variance
in how well vendor 2D code readers perform on varying
surfaces. Knowing which industrial marker and reader to
use for your specific application can be challenging.
We encourage you to allow JETEC to use our expertise
in Mark-Read systems to select the best product marking
and read verification system for your application. Contact
us for free consultation, sample marking, product
demonstration and systems definition.
