Thanks to Clive Hohberger for this posting. “I remember a Tech Support call I took while at Zebra in 1985. The woman explained to me that she printed a 3:1 Code 39 which just fit on her label, but would not read. I duplicated it and realized she had no Quiet Zones. She thought QZs […]
Got the leading Quiet Zone OK but extended a line from the Nutrition Facts area right through the trailing Quiet Zone. Big oops.
Thanks to Matt Swaim who sent this image and question: “Is it possible for two GS1-128 barcodes to have slightly different bar patterns, yet scan the exact same numbers?”
…and for all the wrong reasons. They did the hard part–printed a beautiful looking ITF14 with full surround bearer bars and great press gain control. They even went to the expense of a second pass to provide a clean, crisp white background. And then, OMG, they printed it in red. I’m speechless.
Sort of a cheap shot since it is fairly easy to find bad barcodes on corrugated–but it really shouldn’t be that way. Good barcodes on corrugated are mostly a matter of a well documented process, good controls and operator vigilance.
UPC printed by inkjet at about 170% magnification. A combination of problems here–badly oversprayed and poor control of the carton on the conveyor. Opposite side also very bad but for different reasons, which adds up to process neglect.
Several problems with this EAN barcode. Both quiet zones have been violated, and there are obvious defects in the bars and human-readabales. Very poor print quality overall.
QR Code is designed to withstand a lot of “customization”–hence the owner’s logo in the data section of the symbol. But it cannot survive fixed pattern damage such as the modified position targets.
You will see, the HRI is displayed as mirror-image). In application with high temperatures (about 1250°C) such a minor failure could turn-out as a complete disaster. The trouble here was, that the operator applied the wet slide-label flipped over.
