The present invention concerns a method and a system for controlling the relative position between a printed pat-tern and a non-printed pattern, such as for example a pattern of creasing lines or holes, on a running web-shaped material, by providing the material web with at least one impressed indentation mark with a three-dimensional topographic configuration, at a pre-determined distance from a printed register mark and detecting the marks with a same sensor control system. According to a fur-ther aspect of the invention said controlling method and system is used for the manufacturing of a laminated packaging material, having a printed decor and creased folding lines in register.
L'invention concerne un procédé et un système pour commander la position relative entre un motif imprimé et un motif non imprimé, tels que par exemple un motif de lignes de pliage ou de trous, sur un matériau en bande qui défile, par formation d'au moins un repère d'encoche imprimé sur la bande de matériau selon une configuration topographique tridimensionnelle, à une distance prédéterminée d'un repère d'alignement imprimé, et par détection des repères au moyen du même système de commande par capteur. Selon un autre aspect, le procédé de commande et le système de l'invention sont utilisés pour fabriquer un matériau d'emballage laminé présentant un motif imprimé et des lignes de pliage en alignement.
