ABSTRACT:
A deterrent to counterfeiting of indicias on mailpieces is provided in a method and apparatus for implementing the printing of the indicia using a customized printhead or customized printer drivers such that the dots of the bit-mapped printing are produced by the printer in unevenly spaced rows or columns. The dot size may also be varied in accordance with data from the meter, printed value, variable data such as the date, and forensic data suitably encrypted. When the indicia is scanned, the variations are readily detectable and the information is easily extracted by Postal Authorities.
