Abstract

L'invention concerne un élément d'impression présentant au moins une paire de cylindres constitué d'un cylindre gravé (03) et d'un cylindre de transfert (07). Ce dernier coopère avec un cylindre d'impression (07;28) de façon à permettre à une bande de matière à imprimer, passant verticalement entre ces deux derniers cylindres, d'être enduite d'encre. La circonférence du cylindre de transfert et/ou celle du cylindre d'impression représentent respectivement un multiple entier, différent de un, de la circonférence du cylindre gravé. Le cylindre de transfert et le cylindre gravé présentent respectivement un moteur d'entraînement (08) indépendant mécaniquement de celui de l'autre cylindre.
