Title (EN) SECURITY DEVICE AND AUTHENTICATABLE ITEM
(FR) DISPOSITIF DE SECURITE ET OBJET POUVANT ETRE AUTHENTIFIE
Abstract:
(EN) An authenticatable item and security device carry a number of symbols (4A, 4B, 4C, 6A, 6B, 6C) identifiable to the naked eye, there being at least two sets of at least three symbols. All the symbols within a set are substantially identical, are positioned in a non-overlapping, regular geometric arrangement, and at least one common viewing angle of inclination, exhibit substantially the same optical performance, the optical performance varying with inclination viewing angle.
(FR) Un objet pouvant être authentifié et un dispositif de sécurité portent un certain nombre de symboles (4A, 4B, 4C, 6A, 6B, 6C) identifiables à l'÷il nu, présents sous forme d'au moins deux ensembles d'au moins trois symboles. Tous les symboles dans un ensemble sont pratiquement identiques, sont placés en un agencement géométrique régulier sans chevauchement, et produisent, à au moins un angle d'inclinaison d'observation commun, pratiquement le même effet optique, lequel effet varie selon l'inclinaison de l'angle d'observation.
