Barcode quality has been the primary topic of discussion these past months. It’s important to may industries in a wide variety of applications. What about you out there in the trenches? Barcode [...]
It’s a common scenario: you have a contractor who prints your barcodes. Let’s say it’s a prepaid gift card or a consumer product package. You’ve done your due diligence or so you think: the [...]
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 [...]
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. [...]
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 [...]
The ANSI specification for the quality—and therefore the performance—of linear barcodes tests and grades 9 parameters. Whether or not you believe that ISO or ANSI are legitimate and meaningful as [...]
A short story about the ANSI specification for linear barcode quality. Once upon a time, in the olden days before the ANSI spec, there was something called Traditional verification. This method [...]
Barcode Verifier: The one question to ask… Artful wording and sins of omission are as prevalent in barcode verifier technology as anywhere else. Crafty, lawyerly word-smithing on the very [...]
I presented a workshop on barcode quality at a trade gathering last week. During the Q&A after my talk an attendee asked if a passing ANSI grade “guaranteed” that the barcode was good. The [...]
On June 9, 2011 Honeywell Scanning and Mobility released PRN #11-06, announcing the retirement of their entire line of barcode verifiers. Previously, they had retired a substantial portion of [...]
