Title
(EN) RETROREFLECTIVE SECURITY FEATURES IN SECURE DOCUMENTS
(FR) CARACTERISTIQUES DE SECURITE RETROREFLECHISSANTES DANS DES DOCUMENTS SECURISES
Abstract
(EN)
Retroreflective material is used to create security features in secure documents. Retroreflective material in the document or sheets used for document creation is laser engraved to create optically variable images, identification quality grayscale images, different directional images viewable at corresponding angles of incidence, multidimensional images, and floating images. High refractive index glass beads are selectively applied to areas of a document surface using a variety of techniques. The beads may be applied in the form of a pre-determined or personalized pattern.
(FR)
Une matière rétroréfléchissante est utilisée pour former des caractéristiques de sécurité dans des documents sécurisés. La matière rétroréfléchissante dans le document ou les feuilles utilisées pour produire un document est gravée par laser afin de former des images optiquement variables, des images d'identification en niveaux de gris, différentes images orientables pouvant être vues selon des angles d'incidence correspondants, des images multidimensionnelles et des images flottantes. Des billes de verre à indice de réfraction élevé sont appliquées sélectivement sur des zones de la surface d'un document à l'aide de diverses techniques. Les billes peuvent être appliquées de manière à former un motif prédéterminé ou personnalisé.
