Matrix was designed for small parts marking and is today
used for small electrical parts, by the pharmaceutical
industry for unit dose packaging, by the automotive industry
and by NASA.
Matrix's high degree of redundancy (data is scattered
throughout the symbol) and resistance to printing defects
makes it highly reliable. The symbol's sides can be adjusted
to carry more data in the same space or to fit the product.
It has built-in error correction, but does not include
code has a minimum print contrast requirement of 20% when
reading with an industrial-quality CCD video camera.
Matrix is a 2 dimensional bar code which can store from
1 to about 2,000 characters. The symbol is square and
can range from 0.001 inch per side up to 14 inches per
side. As an example of density, 500 numeric only characters
can be encoded in a 1-inch square using a 24-pin dot matrix
printer. Two adjacent sides of the square symbol are solid
black lines; the other two adjacent sides are printed
as a series of equally spaced square dots.
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.
