Abstract
A system for visually detecting unauthorized print value, such as postal indicia on a mail piece. At least one print image is imprinted on a document based upon predetermined relationships and corresponding to a relationship indicator such that the relationship indicator is made known to an authority who may visually inspect the document to detect whether the value was printed by an authorized machine. The relationship indicator may be dependent on valid indicia, geographical location, time of printing, document position, print graphic or like information. The print graphic may also be imprinted in invisible ink for increased security.
