How to Improve 2D Barcode Grading
A large Midwest flexo label printer was struggling with an order for 6 million UDI labels for an important medical device customer. The press was sitting, the clock was ticking, and the grading [...]
Decoding the ISO 15415 Verification Report: Fixed Pattern Damage
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 [...]
Decoding the ISO 15415 Verification Report: Modulation
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 [...]
Decoding the ISO 15415 Verification Report
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 [...]
