Barcode Problems -Mrs Mays

This barcode has been printed by gravure, a method that is not appropriate for laminated packaging of this type. The glossy surface of the packaging is also reducing the chances of a first time scan.

User comment:
Mrs Mays:

Reverse printed and sandwiched in a laminate.

Magnification is 59% - well below the accepted minimum of 80%.
Recommended minimum for Gravure print is 90%.

Print tolerance at such a small size is not acheivable using Gravure.

High reflectivity of surface is also a probelm as much of the light from the scanner is scattered rather then reflected back to the scanner.
