    - recevoir les premières données de mesure, afin de générer des premières données de commande sur la base des premières données de mesure et pour commander le premier dispositif de tension (9a) conformément aux premières données de commande, de sorte que le premier dispositif de tension (9a) provoque une première tension de bande prédéterminée du substrat d'impression (1) sur le premier dispositif de tension (9a) ; et
    - recevoir les deuxièmes données de mesure, afin de générer des deuxièmes données de commande sur la base des deuxièmes données de mesure et pour commander le deuxième dispositif de tension (9b) conformément aux deuxièmes données de commande, de sorte que le deuxième dispositif de tension (9b) provoque une deuxième tension de bande prédéterminée du substrat d'impression (1) au deuxième dispositif de tension (9b).
  10. Dispositif selon la revendication 9, caractérisé en ce que le dispositif de commande (10) est conçu pour maintenir constante la tension de bande du substrat d'impression (1) le long du trajet de bande devant la table d'impression (3) pendant un processus d'impression et pour maintenir constante la tension de bande du substrat d'impression (1) le long du trajet de bande derrière la table d'impression (3).
  11. Dispositif selon au moins une des revendications précédentes, caractérisé par un dispositif de séparation, comprenant :
    - un dispositif de test (20) comportant un dispositif d'enregistrement d'image (21) qui est configuré pour
    - enregistrer une image de l'image imprimée sur le matériau en bande (1),
    - comparer l'image enregistrée de l'image imprimée sur le matériau en bande (1) avec des données d'image de comparaison,
    - déterminer l'image imprimée en tant qu'image imprimée correcte si, sur la base de la comparaison de l'image imprimée sur le matériau en bande (1) avec les données d'image de comparaison, une correspondance entre l'image imprimée et les données d'image de comparaison est établie, et
    - déterminer l'image imprimée comme une image imprimée incorrecte si aucune correspondance entre l'image imprimée et les données d'image de comparaison n'est établie sur la base de la comparaison de l'image imprimée sur le matériau en bande (1) avec les données d'image de comparaison ;
    - un dispositif de conditionnement (23), qui est configuré pour conditionner le matériau en bande (1) en feuilles individuelles ; et
    - un commutateur de document (25) qui est configuré pour guider une feuille finie sur un d'un premier trajet de transport (26a) et d'un deuxième trajet de transport (26b), dans lequel
    - une feuille conditionnée avec une image imprimée, qui a été déterminée comme étant une image imprimée correcte est guidée sur le premier trajet de transport (26a) et
    - une feuille conditionnée avec une image imprimée qui a été déterminée comme étant une image imprimée incorrecte est guidée sur le deuxième trajet de transport (26b).
  12. Procédé d'impression d'un substrat d'impression (1), comprenant de :
    - appliquer un support d'impression sur un substrat d'impression (1), qui est un matériau en bande (1) qui peut être déplacé le long d'un trajet de bande dans une direction d'alimentation (4), au moyen d'au moins une tête d'impression (14a, 14b) d'une navette de tête d'impression (5), qui est disposée sur un premier côté du substrat d'impression (1), pour générer une image imprimée ;
    - maintenir le substrat d'impression (1) pendant le mouvement d'alimentation du substrat d'impression (1) au moyen d'un dispositif de maintien (11) d'une table d'impression (3), qui est disposée en face de la navette de tête d'impression (5) sur un deuxième côté du substrat d'impression (1), de sorte que pour l'impression, un mouvement relatif entre la table d'impression (3) et le substrat d'impression (1) soit empêché pendant le mouvement d'alimentation; et
    - déplacer la navette de tête d'impression (5) lorsque le support d'impression est appliqué sur le substrat d'impression (1) dans et à l'encontre d'une direction de mouvement de navette s'étendant transversalement à la direction d'alimentation (4) du substrat d'impression (1), de sorte que le mouvement d'alimentation du substrat d'impression (1) dans la direction d'alimentation (4) et le mouvement de la navette de tête d'impression (5) transversalement à la direction d'alimentation (4) établisse un positionnement de la navette de tête d'impression (5) au-dessus du substrat d'impression (1) afin de générer l'image imprimée sur le substrat d'impression (1), dans lequel la table d'impression (3) déplace le matériau en bande (1) le long du trajet de bande dans une direction d'alimentation (4) et la table d'impression (3) se déplace dans la direction d'alimentation (4) et à l'encontre de la direction d'alimentation (4).
  13. Procédé selon la revendication 12, caractérisé par au moins une des étapes suivantes lors de l'application du support d'impression sur le substrat d'impression (1) :
    - déplacer le substrat d'impression (1) le long du trajet de bande, dans lequel la table d'impression (3) effectue un mouvement d'alimentation tandis que le dispositif de maintien (11) maintient le substrat d'impression (1) de sorte que le mouvement d'alimentation soit transféré sur le substrat d'impression (1) est transféré et la table d'impression (3) provoque un mouvement d'alimentation du substrat d'impression (1) le long du trajet de la bande ; et
    - déplacer la navette de tête d'impression (5) dans et à l'encontre d'une direction de déplacement parallèle de navette qui s'étend parallèlement à la direction d'alimentation (4) du substrat d'impression (1).
