Le système d'alimentation en encre comprend au moins deux cylindres monochromes (5a,5b, 5c) et des rouleaux de distribution correspondants (6a, 6b, 6c) et des rouleaux d'encrier (7a, 7b, 7c), et comprend en outre un dispositif à cylindre de collecte de couleur (4), le dispositif de cylindre de collecte de couleur (4) comprenant au moins un premier cylindre collecteur de couleur (4-1), au moins un deuxième cylindre collecteur de couleur (4-2) espacé du premier cylindre collecteur de couleur (4-1), et une courroie de cylindre collecteur de couleur (4-3) qui entoure les premier et deuxième cylindres collecteurs de couleur. La courroie de cylindre collecteur de couleur (4-3) est apte à être en contact avec le cylindre porte-plaque (2) de l'imprimante (1) au moyen du premier cylindre collecteur de couleur (4-1) et à être en contact avec les cylindres monochromes (5a,5b, 5c) au moyen du deuxième cylindre collecteur de couleur (4-2), et la courroie de cylindre collecteur de couleur (4-3) est apte à se déplacer avec la rotation des premier et deuxième cylindres collecteurs de couleur, transférant ainsi l'encre des cylindres monochromes (5a,5b, 5c) au cylindre porte-plaque (2) de l'imprimante (1). L'invention concerne également une imprimante comprenant le système d'alimentation en encre, l'utilisation du système d'alimentation en encre dans une imprimante, et un procédé d'impression.
