Title
(EN) SECURITY ELEMENT AND METHOD TO INSPECT AUTHENTICITY OF A PRINT
(FR) ELEMENT DE SECURITE ET PROCEDE PERMETTANT D'INSPECTER L'AUTHENTICITE D'UNE IMPRESSION
Abstract
(EN) The invention relates to a security element applied onto printing substrates (bankĀ¬ notes, securities, product packagings, identity cards/labels or other similar documents) by printing, comprising a unique identifier as primary information visible to the naked eye and secondary information protecting against copying non-visible to the naked eye. The unique identifier is typically a point code. Said secondary information is represented by a structure with the largest dimension of 2 to 40 microns, and due to printing distortions arising when the security element is applied onto a printing substrate, said secondary information is non-reconstructable from the print of the security element and a statistically analyzable inherent feature is associated to it. The invention also relates to a printed matter with such an inventive security element and to a method to check authenticity of a printed matter with the inventive security element in visible light (380-750nm).
