Title (EN) SECURITY DOCUMENT WITH SECURITY MARKING
(FR) DOCUMENT DE VALEUR A MARQUAGE DE SECURITE
Abstract:
(EN) The security marking for security documents, in particular papers representing a value, consists of a plurality of circular or elongate holes (11), which are arranged in parallel rows (14) in a printed area (5) of the document. The diameter (a) of the holes is chosen such that they are practically invisible with bare eyes in reflection, but become well visible when the document (10) is held against a light and viewed in transmission. The holes (11) are generated by laser pulses. The marking can be produced quickly and easily and it can be verified without technical aids.
(FR) Marquage de sécurité pour documents de valeur, en particulier des papiers représentant une valeur, constitué d'une pluralité de trous circulaires ou oblongs (11) disposés en rangées parallèles (14) dans une zone imprimée (5) du document. Le diamètre (a) des trous est choisi de façon à être pratiquement invisible à l'oeil nu en réflexion, mais devient bien visible lorsque le document (10) est tenu à la lumière et examiné en transmission. Les trous (11) sont produits par des impulsions laser. Le marquage peut être produit rapidement et facilement et peut être vérifié sans outils techniques.
