Le dispositif de traction 8, associé aux autres unités de la presse, permet d'imprimer une bande de papier et de la réceptionner dans le dispositif de découpe et d'empilage 10, sans sécher cette bande de papier 12 et par évaporation des solvants de l'encre.The traction device 8, associated with the other units of the press, makes it possible to print a strip of paper and to receive it in the cutting and stacking
L'image est imprimée par l'encre 24 contenue dans le réservoir d'encre 22. De manière avantageuse, l'encre 24 est une encre siccative, ou une encre sans eau (« waterless »), ou une encre bi-composante. Le séchage des encres siccatives est la combinaison d'un premier phénomène dit « la pénétration dans le support » et d'un second phénomène dit « l'oxydo-polymérisation des vernis constitués d'huiles et de résines ».The image is printed by the
Les encres sans eau (« waterless ») sont utilisées avec des plaques d'impression spécifiques permettant de définir des zones non imprimantes sans faire appel au procédé lithographique classique fondé sur le refus de l'encre grasse par une surface hydrophile préalablement humidifiée. L'utilisation de ces encres peut être envisagée au même titre que les encres siccatives conventionnelles vues précédemment et permet de se dispenser d'un sécheur, ou de le concevoir de manière moins encombrante.The waterless inks are used with specific printing plates to define non-printing areas without using the conventional lithographic process based on the rejection of the greasy ink by a previously moistened hydrophilic surface. The use of these inks can be considered in the same way as the conventional drying inks previously seen and can be dispensed with a dryer, or design less cumbersome.
Les encres fixables par la chaleur ("heat-set") par contre sèchent par évaporation des solvants minéraux mélangés à la résine. Les encres UV sèchent par polymérisation de la résine sous l'effet d'un rayonnement ultraviolet.Heat-set inks, on the other hand, dry by evaporation of the mineral solvents mixed with the resin. The UV inks dry by polymerization of the resin under the effect of ultraviolet radiation.
