The invention concerns a method for printing security graphics (EGS) on a support that is to be secured, characterised in that it involves using, in combination, at least three different types of EGS taken from a group of eligible EGS items, and in that said EGS items that are used are interdependent by construction, such that a modification to one of the EGS items forming the print item automatically results in an identifiable inconsistency. |
