Abstract

L'invention concerne une unité d'impression comprenant au moins deux paires de, dans chaque cas, deux cylindres (16, 17), à savoir un cylindre de transfert (17) et un cylindre porte-clichés associé (16), avec une circonférence correspondant au moins à deux pages imprimées disposées l'une à la suite de l'autre dans le sens périphérique. Les cylindres de transfert coopèrent avec un cylindre d'impression commun, dans une position de mise en marche d'impression, de manière à former un point d'impression. Les cylindres de deux paires diamétralement opposées sont disposés dans chaque cas de sorte que leurs axes de rotation (R16, R17) se trouvent dans un plan commun (G) conjointement avec l'axe de rotation (R18) du cylindre d'impression en position de mise en marche d'impression.
