摘要:
The present invention relates to the field of the intaglio printing process. In particular, the present invention relates to a method that combines intaglio inks curable by oxidation with UV-VIS-curable intaglio inks on one intaglio plate or cylinder. The disclosed method results in an intaglio printed security element using advantageously the unalike properties of the different inks while enabling the printing on a standard printing press in one printing step.

An apparatus for manufacturing a decorative film for semi-finished products such as leather, imitation leather and fabric includes a first gravure-printing station (5) consisting of a photo-engraved cylinder (5a) that picks up a molten thermoplastic material from an underlying heated tray (5b) and transfers it to a print substrate (2) with the aid of an overlying rubber cylinder (5c), followed by a first cooling station (6) suitable to cool and fix the thermoplastic material applied to the print substrate (2), as well as a second gravure-printing station (9) arranged downstream from the first cooling station and consisting of a photo-engraved cylinder (9a) that picks up a second molten thermoplastic material from an underlying heated tray (9b) and transfers it to the print substrate (2) with the aid of an overlying rubber cylinder (9c), followed by a similar second cooling station (10). The invention also relates to the manufacturing method of said decorative film and to the film thus manufactured.

The present invention is directed to a floor panel that is processed on roll equipment, whereby a decorative design consisting of elongated striations is printed with the elongated striations oriented in an across-machine direction. The decorative design is printed on a print layer and is subsequently laminated to a substrate layer. The laminated flooring material is then cut such that the elongate sides of the panels are cut in the across machine direction. This results in a floor panel with greater dimensional stability on the elongate side.

The invention relates to an inking unit of a gravure printing machine comprising a gravure printing cylinder and an inking device inking the gravure printing cylinder with an ink. In order to simplify the proofing process of a gravure printing machine, the inking unit is removed from said machine in such a manner that said inking unit remains in a ready-to-print state.
摘要:
Rotationsdruckmaschine mit einem elektrisch im Wesentlichen isolierenden Bedruckstoff (12) auf einer Abwickelrolle (11), von der der Bedruckstoff zu mehreren in Durchlaufrichtung des Bedruckstoffes hintereinander angeordneten Druckwerken (1.1-1.4) geführt wird, die jeweils einen Druckzylinder (2.1-2.4) und einen Presseur (4.1-4.4), die gegensinnig aufeinander abrollen, und eine Einrichtung zum Erzeugen eines elektrischen Felds (9.1-9.4) im Druckspalt (10.1-10.4) zwischen Druckzylinder und Presseur aufweisen, wobei die Einrichtungen zum Erzeugen eines elektrischen Feldes (9.1-9.4) verschiedener Druckwerke mit Hochspannungsquellen (5.1-6.4) verbunden sind, die verschiedene Polaritäten aufweisen, und mit einer Aufwickelrolle (15), auf die der Bedruckstoff hinter den Druckwerken geführt wird, dadurch gekennzeichnet, dass jede Einrichtung zum Erzeugen eines elektrischen Feldes (9.1-9.4) über eine Umschalteinrichtung (7.1-7.4) mit einer Hochspannungsquelle positiver Polarität (5.1-5.4) und einer Hochspannungsquelle negativer Polarität (6.1-6.4) verbunden ist, sodass durch Umschalten der Umschalteinrichtung (7.1-7.4) wahlweise eine Hochspannung positiver Polarität oder eine Hochspannung negativer Polarität an die Einrichtung zum Erzeugen des elektrischen Feldes (9.1-9.4) anlegbar ist.
