Barcode Labels and Ribbons

Thursday, April 8th, 2010

“Consumables” for your inkjet printer at home include paper and ink cartridges. Consumables for a dedicated bar code printer (such as the Zebra ZM600 or RP4T and Datamax O’Neil I-series) include rolls of labels and ribbons. Bar code printers are thermal, meaning the printhead is heated to make an image.

In a direct thermal printer there is no ribbon; instead the labels are coated with a heat sensitive material and the printhead ‘burns’ an image into the coating. In a thermal transfer printer the heated printhead melts a carbon film ribbon producing a bar code symbol. Thermal transfer ribbons are only god for one pass and must be replaced with each roll of labels.

Another consumable item with a bar code printer is the thermal printhead. With good preventive maintenance the printhead will last a long time. However when not cleaned and adjusted regularly, or when using low quality labels, the printhead will burn out elements thereby degrading the quality of the bar code symbol. ADC Integrated Systems can provide you with bar code media solutions for any type of printer application.

How Bar Code Works

Wednesday, March 31st, 2010

Each barcode symbol is printed to certain specifications; these define the size of each bar, how sharp the edges of each bar should be, how much contrast there should be between the black bar and the background it’s printed on. Barcode labels are graded based on how well they meet the specification; they are given a letter grade A, B, C or F.

Why is this important? Because big companies like Walmart and Target rely on these barcode symbols to ship and receive products to their stores. Every shipping container barcode that doesn’t scan costs Walmart in time and money. So in order to give their suppliers an incentive (?) to print good bar codes, Walmart (and other retailers) FINE companies that print poor bar codes. These fines can add up to tens of thousands of dollars to the supplier.

The device used to grade bar code symbols is called a Verifier. This is simply a bar code scanner with a computer attached that compares the actual printed bar code symbol to the specification. Anything less than a C grade can bring large fines to the supplier. Some companies send workers armed with verifiers to check a certain percentage of boxes by hand. But some companies want to make sure the labels are good as they are being printed. This requires a bar code printer with a verifier built in. Barcode printers such as the Printronix T5000r use Online Data Verification to check each label as it comes out of the printer.

If a label fails the check it is automatically canceled and a new label printed. If you don’t verify currently, ADC can do a no-cost, no-obligation review of your current labels with recommendations on how to improve them. You can contact us via the website www.adcisi.com.

Why Verify Barcode Labels?

Laser Scanner or Digital Imager?

Wednesday, August 5th, 2009

A scanner is a device that “looks” at a bar code; the first step in decoding the information contained in the bar code. Diode laser scanners have been around for close to two decades. Digital imagers are somewhat newer.

A laser scanner uses a dot of laser light to produce a signal. A digital imager ‘takes a picture’ of the bar code symbol. Which is “better”?

A new case study from our partner, Motorola, provides some answers. Access this PDF report HERE Contact ADC to request a scanner demo on your bar code symbols.
