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.
