Abstract

L'invention concerne un procédé pour faire fonctionner une machine d'impression (1), une bande de matériau à imprimer (20) pouvant être imprimée, de préférence des deux côtés, dans la région d'au moins deux unités d'impression (11 à 14), et au moins une unité d'impression étant conçue comme unité d'impression supplémentaire. Selon ledit procédé, la vitesse de transport de la bande de matériau à imprimer (20) est réduite lorsqu'au moins une unité d'impression (15'), qui est conçue comme unité d'impression supplémentaire, passe à un état de non impression en vue de la réalisation de travaux d'équipement et/ou de maintenance sur ladite unité d'impression, tandis que la bande de matériau à imprimer (20) est en même temps imprimée dans la région d'au moins une autre unité d'impression (11 à 14).
