Abstract

La présente invention concerne un procédé et un système de repérage pour machines d'impression flexographique permettant de définir le repérage du moyen de contact de substrat d'impression (13, 14a, 14b, 15, 16, 21-24) d'une machine d'impression flexographique. Le procédé comprend les étapes consistant à détecter la position d'au moins deux emplacements pour support d'impression (13, 14a, 14b, 15, 16, 21-24), comparer les valeurs réelles détectées pour la position avec des valeurs définies pour déterminer les positions relatives, et déterminer un placement de repérage adéquat en fonction des positions relatives déterminées.
