Why Do Barcodes Misread?

So much technology is involved with barcodes, from designing and printing them to scanning and decoding them, it is often overlooked that this is as much art as science. Sometimes there is not a readily evident technological explanation for why a barcode misreads—there is always a reason but it can be difficult to tease out…

How Do Barcode Scanners Work?

A simple enough question and it leads to a qualifying question—do you really want to know? So we’ll start with the simplest answer: a barcode scanner works on the basis of reflectivity, or more precisely on reflective differences in the barcode. Still interested? OK. Barcode scanners decode linear barcodes by finding the edges of the…

Barcode 201: How do Barcodes Work?

How Do Barcodes Work? If you refer to all barcodes as UPC’s, this article won’t be interesting to you. But if you know that all barcodes are not UPC’s, it may interest you to know that different symbologies encode the data very differently, and I’m not talking about how the data itself is arranged: that’s…

Ten Most Common Thermal Printing Barcode Problems and How to Prevent Them

The use of thermal and thermal transfer printing continues to rise and many if not most of those labels include barcodes—thermal is a great technology for barcodes, especially variable or one-at-a-time label printing. Robust, industrial grade thermal printers perform well in less than pristine environments such as warehouses, packaging companies and shipping departments. But heavy…
