Title
(EN) SECURITY ELEMENT AND METHOD TO INSPECT AUTHENTICITY OF A PRINT
(FR) ÉLÉMENT DE SÉCURITÉ ET PROCÉDÉ PERMETTANT D'INSPECTER L'AUTHENTICITÉ D'UNE IMPRESSION
Abstract
(EN) The invention relates to a security element applied onto printing substrates (bank¬ 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).
(FR) La présente invention concerne un élément de sécurité appliqué par impression sur des substrats dédiés à l'impression (billets de banque, valeurs, emballages de produits, étiquettes/cartes d'identité, ou autres documents similaires), comprenant un identificateur unique en tant qu'information primaire visible à l'œil nu et une information secondaire de protection contre la copie non visible à l'œil nu. L'identificateur unique est typiquement un code à points. Ladite information secondaire est représentée par une structure dont la dimension la plus grande fait de 2 à 40 microns, et, du fait des distorsions d'impression se produisant lorsque l'élément de sécurité est appliqué sur un substrat dédié à l'impression, ladite information secondaire ne peut pas être reconstruite à partir de l'impression de l'élément de sécurité ; de plus, une caractéristique inhérente pouvant être analysée de manière statistique lui est associée. L'invention concerne également une matière imprimée dotée d'un élément de sécurité selon l'invention, ainsi qu'un procédé servant à vérifier l'authenticité d'une matière imprimée dotée de l'élément de sécurité selon l'invention à la lumière visible (380 à 750 nm).
