<p>Method and apparatus for applying unique composite indicia or makings to a succession of articles, in which each unique composite indicium comprises two or more indicium. At least part of each of the indicia may be co-located at a predetermined location on the article with such co-location being unique or distinct for each composite indicium for each article. The indicium may be overprinted with one or more images, logos or colour-shemes. A code (e.g. an alphanumeric code) that is stored in a database may be derived from the composite indicium from one or more mathematical properties. The code may be later accessed for identifying or verifying the article with indicium.</p> |
