Abstract:
A parcel label design system, comprising:a) a label specification encoder, responsive to a label design specification, for providing a neutral language specification of the label design, the neutral language specification suitable for automatic translation into control codes and printer commands for a plurality of types of label printer; and b) a label design generator, responsive to the neutral language specification, and further responsive to a target printer type, for providing a printer-specific label design, wherein the label specification encoder includes a means for generating a check digit, as part of a bar code, for detecting tampering of the bar code, and the check digit is computed as a mathematical combination of pre-determined weights associated with each bar of the bar code, the value associated with each bar of the bar code, and a predetermined scaling operation to ensure that the check digit falls within a pre-determined range.
