Abstract: The invention provides stable nucleic acid-tagged ink compositions suitable for printing an ink mark on an object as an identifier or for authentication of goods, and methods of marking an article with such a mark. These ink compositions contain a specific nucleic acid of known length and sequence that can be deposited on an article by inkjet printing or thermal transfer printing to produce a mark, which may be visible or invisible, covert or overt. These ink products are stable and can accurately deliver an amount of nucleic acid tag that can be removed or sampled and analyzed by known DNA analytical methods to detect the specific nucleic acid on the marked article but which cannot be identified without previous knowledge of the nucleic acid sequence in the mark. The invention also provides methods of applying these tagged marks using inkjet printers and printer systems, and the systems for using the tagged ink compositions.
