Quality Control is as important as the product. Here is a classic example of issues of print quality encountered everyday.
Hello,, Please look for attached and let us know about the result. The format of the GS1-128 Barcode Label meet the standard and Barcode needs to be at least 3.02″ in lenth, 1.25″ in height with a .25″ quiet zone from the edge on both side. Thank you, K.
Seen in Mumbai when I was running some bar coding workshops in 2008. 28% magnification!
This little UPC is way undersize and left quiet zone is barely intact
Another playful–and perfectly working–UPC from the folks at Bigelow. Love their teas and their fun barcodes!
White-on-black won’t work for a UPC
This should have been on Swiss cheese!
