If ink bleeds or smudges on a barcode, a scanner will not be able to identify it. If the lines of a barcode are not spaced correctly, it will be impossible to read. Ink bleeding can cause lines to appear closer together than they should be, as can using an incorrect font to print a barcode. Dirt or water damage can also cause lines to be distorted. None of this is good. Barcode scanning will not end well if any of the above is in play.
Barcodes are valuable allies and should be protected. Don’t let ink bleed kill your barcodes!
