Abstract

Le problème décrit par la présente invention est de pourvoir à un procédé d'impression au moyen duquel il est possible d'aligner efficacement les positions d'impression d'une impression par jet d'encre et d'une impression par rotative avec une grande précision. La solution selon l'invention porte sur un procédé d'impression comportant les étapes consistant à : imprimer, sur un objet (W) devant faire l'objet d'une impression, un repère de référence (7) pour l'objet (W) devant faire l'objet d'une impression au moyen d'un dispositif d'impression par jet d'encre (40) ; réaliser une héliogravure sur l'objet (W) devant faire l'objet d'une impression au moyen de cylindres porte-plaque (11a, 11b, 11c) d'une pluralité d'unités d'héliogravure (10a, 10b, 10c), et imprimer des repères (8a, 8b, 8c) sur l'objet (W) devant faire l'objet d'une impression ; et détecter chaque repère parmi le repère de référence (7) sur l'objet (W) devant faire l'objet d'une impression et les repères (8a, 8b, 8c) sur l'objet (W) devant faire l'objet d'une impression qui ont été envoyés par les unités d'héliogravure, au moyen de capteurs de détection (15a, 15b, 15c) de repères des unités d'héliogravure (10a, 10b, 10c). L'amplitude de différence des positions du repère de référence (7) et des repères (8a, 8b, 8c) sur l'objet (W) devant faire l'objet d'une impression qui ont été détectés au moyen des capteurs de détection (15a, 15b, 15c) de repères est calculée à l'aide d'un dispositif de commande de repérage (30), et la position de l'objet (W) devant faire l'objet d'une impression est ajustée sur la base de l'amplitude calculée de différence.
