Barcode Problems - Tesco Value Dishcloths
This EAN 13 barcode has been printed by flexography (flexo) - and there are tell-tale artifacts of flexo printing near the printed edges of the printed image which result in a barcode that does not meet the standard. In this case, a large magnigfication of barcode may have improved the quality. Remember, the higer the magnification, the more tolerance in the barcode.

| Flexo printed at too small a magnification for the process. Bars overprinted causing ghosting of bars. Bars edges not seen correctly therefore giving a low Defect grade. |
