The Scan Reflectance Profile or SRP is a graphic representation of the changing reflectance values of a linear bar code across its width, from leading quiet zone to trailing quiet zone. As the [...]
“Bar code quality just isn’t a problem anymore—not nearly like it was back in the ‘80’s.” I hear this all the time. The rationale is often that print technology is so much better than it was, and [...]
First of all, what does it mean when bar code verifiers are ISO compliant? It means the test device has been independently tested and shown to be operating within stated hardware specifications [...]
Maybe the first question is why do you test a bar code—why is it necessary? It is necessary to test a bar code because when it doesn’t work right, it causes huge problems and potentially huge [...]
The term “high performance” associated with a bar code usually equates to a very high, nearly 100% first-read rate. That of course is the upper limit of how good a bar code could possibly be [...]
We exhibited our barcode quality products and services at a local trade show recently. One of the visitors commented that barcode quality wasn’t any longer as important an issue in recent years [...]
The ISO barcode quality specification for testing and grading of linear barcodes is often misquoted and misunderstood. Two frequently misrepresented parameters for ISO 15416 are the ten-scan [...]
Apologies to those of you for whom this is all review—it may be news to others. Barcode Quality begins way before the press Barcode quality isn’t just a printing issue—it begins in prepress. [...]
How can you determine what barcode colors are acceptable for linear barcodes? Do you have to actually print a barcode before you can tell if it will work? No! You can fairly easily test possible [...]
Of all the ANSI/ISO parameters, decodability is the one that confounds and confuses most people. Attempts to define it in simple terms (“Decodability is the amount of tolerance left for the [...]
