Each barcode symbol is printed to certain specifications; these define the size of each bar, how sharp the edges of each bar should be, how much contrast there should be between the black bar and the background it’s printed on.
Barcode labels are graded based on how well they meet the specification; they are given a letter grade A, B, C or F. Why is this important? Because big companies like Walmart and Target rely on these barcode symbols to ship and receive products to their stores. Every shipping container barcode that doesn’t scan costs Walmart in time and money.
So in order to give their suppliers an incentive (?) to print good bar codes, Walmart (and other retailers) FINE companies that print poor bar codes. These fines can add up to tens of thousands of dollars to the supplier.
The device used to grade bar code symbols is called a Verifier. This is simply a bar code scanner with a computer attached that compares the actual printed bar code symbol to the specification. Anything less than a C grade can bring large fines to the supplier.
Some companies send workers armed with verifiers to check a certain percentage of boxes by hand. But some companies want to make sure the labels are good as they are being printed. This requires a bar code printer with a verifier built in.
This printer – the Printronix T5000r – uses Online Data Verification to check each label as it comes out of the printer. If a label fails the check it is automatically canceled and a new label printed.
If you don’t verify currently, ADC can do a no-cost, no-obligation review of your current labels with recommendations on how to improve them. Contact us for more information.
