Barcode News

No this article is not actually about barcode news, it is of course about bar code quality. But when you think about it, almost anything having to do with barcode news is by definition about bar code quality. Incidentally the very best place to find out about barcode news is at a great newsletter called…

The Dangers of an Old Verifier

Verifiers are expensive. Sometimes companies are reluctant to invest the money and once they finally do, they are reluctant to let go of an old verifier that still works. But sometimes an old verifier that works is worse than one that does not work. Here are some reasons why. “Working” is one thing; “functioning properly”…

Bar Width Reduction

Bar width reduction or BWR is a method for adjusting the graphics design file of a barcode to compensate for press gain. Press gain or ink spread is one of the most common causes of poor barcode performance. Bar width reduction is a compensation for press gain Not all barcode design software provides for bar…

Bar Codes on Corrugated

It is a widely accepted fact that printing bar codes on corrugated is a challenge. TAPPI and other trade groups recognize that the verification grade is seldom better than ANSI D (ISO 0.5-2.3) due to the low reflectance value of the bare kraft substrate. There is very little that can be done to improve this,…

Scan Reflectance Profile

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 scanner detects and, through a timing algorithm, “measures” the widths of each element (bar and space), it acquires a reflectance reading that…
