| Accurate,
functioning bar code symbols have become a critical requirement at
all stages of the supply chain – especially as manufacturers,
suppliers, and retailers all need to meet stringent compliance targets.
Poor quality bar code symbols can lead to losses in productivity,
massive shipping returns, and even supplier fines. Bar code verification
during printing, application or before shipment saves time, money
and trouble. |

Bar code verification
is the bridge between creating the bar code image and successful,
accurate and efficient scan rates, an important part of any bar
code system. Once used exclusively by large printing houses and
/ or major label vendors, bar code symbol verification is now commonly
used for on-site demand printing as well as on warehouse receiving
docks. Verifiers can be integrated, connected to the printer or
conveyor system, or they can be used in a stand-alone configuration.
These quality control instruments grade a bar code symbol’s
print quality based upon ISO and ANSI’s published criteria.
Some verifiers also provide results based on industry application
standards to ensure conformance to National, Industrial and International
standards.
Use of bar code
verification as part of your quality control process provides an
important step in increasing your AIDC system’s operating efficiency
by economically reducing potential problems caused by poor symbol
quality.
As AIDC applications
become more and more critical to a company’s success, the cost
of bar code scanning failure becomes more significant. Such giant
merchandisers as Wal-Mart, for example, have become famous for leveling
whopping fines of $50,000 or more on suppliers whose product
labels repeatedly misread. Consequently, bar code verification systems,
once exclusively used by printers and label vendors, are now commonly
used for on-site printing. Verifiers will grade a symbol unacceptable
or by degrees of acceptability based upon ANSI’s published
criteria, known as the Bar Code Print Quality Guideline. Verification
devices can be integrated in-line, attached to the printer while
monitoring the quality of every printed label or they can be used
in a standalone configuration to audit batches of labels. In either
case, verification can’t completely eliminate bar code performance
problems. Verification can, however, provide a quantitative measure
of print contrast and derive wide-to-narrow ratios, checking printed
symbol conformance against symbology print quality standards.
