Whether you are using 1D barcodes such as GS1-128 or 2D symbols such as Data Matrix codes for UDI compliance marking, UDI barcode verification is essential for assuring barcode quality. Here are [...]

We run across some very interesting barcodes and probably every imaginable mistake, that leave you wondering, “How did they do that?” And some of the mistakes we encounter are so subtle, we [...]

It can be difficult and confusing to relate the ISO parameters on the verification report to what is actually happening in a barcode. Here we will attempt to connect those dots in a way that [...]

Here we go again with wild and crazy barcodes. The barcode risk management business can seem oppressively serious, but that is simply not true: it can be downright fun! We are inviting you to [...]

Does an A grade guarantee scanning success? Does an F grade guarantee scanning failure? Did your mother not teach you, there are no guarantees? “If there are no guarantees, why did I buy a [...]

Barcodes that don’t work right can be a liability. Managing that risk begins with a well conceived, diligently executed barcode quality procedures document. Yes, a document, a step-by-step [...]

Recently we wrote about how to make sure your barcode verifier is accurate, by using a Performance Qualification test kit. The PQ test kit is a card deck of precise images, each displaying an [...]

After Modulation, discussed previously, Fixed Pattern Damage (FPD) is likely the next most prevalent problem with 2D barcodes. The “fixed pattern” referenced are the omnipresent locator targets [...]

In a previous article, we took a bird’s eye look at the ISO 15415 report, and defined the pass/fail and graded parameters that are the basis for the final symbol grade. Understanding the [...]

Scanning a barcode, whether a 1D like UPC or a 2D like Data Matrix, is based on reflectivity, specifically the reflective differences between the barcode image and its background. At the top of [...]
