FIELD: physics, labelling. ^ SUBSTANCE: invention relates to an electric discharge method of marking thin-sheet dielectric articles, particularly strictly accountable paper documents and paper money. The method of making an irreproducible identification mark involves deposition of an identification number, an information array and an irreproducible picture through discharges and entering the irreproducible picture into a database. The irreproducible picture is created through discharge between main and auxiliary electrodes and an identifiable dielectric article, for example paper, is placed between the main and auxiliary electrodes. ^ EFFECT: disclosed document with an irreproducible identification mark ensures high security from replication and forgery. ^ 3 cl, 3 dwg, 1 ex |
