Bowe Bell & Howell MVP Postal Verifier

The MVP uses established USPS MERLIN criteria to deliver reliable on-demand confirmation of a mail piece’s compliance with DMM barcode, reflectance and contrast ratio standards. Mail Verifier Plus verifies USPS POSTNET, PLANET and IMB (Intelligent Mail Barcode). This is the only commercially available product able to perform a full range of MERLIN-compliant barcode and reflectance…

Axicon 6015

The 6015 is a small, simple package loaded with unique, user-friendly features. It is ISO/ANSI compliant to verify virtually all 1D linear barcodes up to 72mm or 2.8: wide, including quiet zones. Using it—and looking at it—you can tell that Axicon did not start from other popular platforms and build on (or improve) their attributes.…

Verification and Validation

“Validation is to spelling what verification is to penmanship.”   Think about it. Spelling is making sure the word is really a word. After all, a misspelled word may not be recognizable as a word at all, and therefore devoid of meaning. Utterly useless, or worse: a misspelled word could closely represent something it was…

Modulation and Decodability

Modulation and decodability are easy to understand if you are familiar with the Scan Reflectance Profile or SRP. This is discussed in previous articles in this blog. The Scan Reflectance Profile is a powerful diagnostic tool for gauging what is going on with a barcode symbol. The SRP makes it easier to talk about reflectivity attributes…

Edges: Bar and Space Transitions

As we’ve said before, barcode scanners work based on reflectivity and contrast. The messages encoded in linear barcodes are decoded on the basis of the scanner’s ability to detect reflective and contrast differences. In a pattern of lines and spaces, these critical differences are demarked by the edges—the places where the bar ends and the…

Minimum Reflectance and Symbol Contrast

Minimum Reflectance and Symbol Contrast are tested by taking reflectance readings from the symbol—specifically the maximum reflectance value and the minimum reflectance value, and applying a calculation to those values. Minimum Reflectance is a Pass/Fail parameter A barcode image must have a minimum amount of reflective difference between the barcode and the background for the…
