Une surface extérieure du rouleau pelliculeur présente une structure régulière formée par des sillons. La structure de la surface extérieure du rouleau pelliculeur est formée par plusieurs sillons rectilignes parallèles les uns aux autres à droite par rapport à un axe de rotation du rouleau pelliculeur et par plusieurs sillons rectilignes parallèles les uns aux autres à gauche par rapport à l'axe de rotation du rouleau pelliculeur. Plusieurs des sillons à droite et plusieurs des sillons à gauche sont disposés de manière à se croiser les uns avec les autres. Les surfaces délimitées respectivement par au moins un sillon à droite et au moins un sillon à gauche et formant respectivement une partie de la surface extérieure du rouleau pelliculeur constituent additionnées un pourcentage de portée de maximum 10 % par rapport à la surface extérieure du rouleau pelliculeur considérée en tant que surface enveloppante fermée. Le train de rouleaux comporte au maximum cinq points de contact le long d'un trajet de transport s'étendant du rouleau pelliculeur au cylindre gravé et servant au transport de l'encre d'imprimerie. La surface extérieure du rouleau pelliculeur présente une dureté différente selon son pourcentage de portée, et ce de telle manière que ladite surface extérieure est constituée d'un matériau présentant une dureté d'au moins 500 HV10 pour un pourcentage de portée compris entre plus de 0 % et au maximum 1 %, d'un matériau présentant une dureté comprise entre plus de 100 HV10 et de moins de 500 HV10 pour un pourcentage de portée compris entre plus de 1 % et au maximum 5 %, et d'un matériau présentant une dureté comprise entre plus de 30 HV10 et au maximum 100 HV10 pour un pourcentage de portée compris entre plus de 5 % et au maximum 10 %.
