A printing system (10) which uses a single layer printing member (100) coated onto a cylinder (12) is provided. For waterless offset application, the single layer printing member consists of an oleophobic imaging layer (100) containing an oleophobic resin, coated on an oleophilic cylinder (12), or for wet application, the single layer (100) may be hydrophilic, coated on an oleophilic cylinder (12); or vice versa. The single layer printing member is composed of a resin having either oleophobic, hydrophilic, or oleophilic properties and may contain infrared absorbing components. The printing system further contains a coating head (20) for applying the single layer, a dryer/cross-linker (24) for curing the applied layer, an imaging system (16), plate cleaner (25) for cleaning the imaged layer, and erasing system (22) for removing the layer from the cylinder.
La présente invention concerne un système d'impression (10) qui utilise un élément imprimant monocouche (100) appliqué sur un cylindre (12). Pour l'application par transfert sans eau, l'élément imprimant monocouche est constitué d'une couche imageuse oléophobe (100) contenant une résine oléophobe appliquée sur un cylindre oléophobe (12). Mais pour l'application par transfert humide, la monocouche (100) peut être hydrophile, appliquée sur un cylindre oléophile (12) ou réciproquement. L'élément imprimant monocouche, qui est composé d'une résine présentant des caractéristiques oléophobes, hydrophobes ou oléophiles, peut contenir des composants absorbant l'infrarouge. Le système d'impression comporte en outre une tête applicatrice (20) servant à l'application de la monocouche, un dessicatif/réticulant (24) permettant de durcir la couche appliquée, un nettoyeur de plaque (25) du système imageur (16) servant à nettoyer la couche des images, et un système d'effacement (22) servant à supprimer la couche du cylindre.
