ABSTRACT:
A method of identifying a franking machine used to print franking impressions is disclosed. Ink used by the franking machine contains an identification tag unique to each franking machine, or to a group of franking machines, and the impression printed by the franking machine is sensed to determine the identity of the tag and hence to determine the identity of the franking machine used to print the impression. The tag may be chemically unique or may be physically unique. The physically unique tag may have a unique shape or size or may bear a unique marking.
