Abstract:
There is described an intaglio printing plate coating apparatus comprising a vacuum chamber having an inner space adapted to receive at least one intaglio printing plate to be coated, a vacuum system coupled to the vacuum chamber adapted to create vacuum in the inner space of the vacuum chamber, and a physical vapour deposition (PVD) system adapted to perform deposition of wear-resistant coating material under vacuum onto an engraved surface of the intaglio printing plate, which physical vapour deposition system includes at least one coating material target comprising a source of the wear-resistant coating material to be deposited onto the engraved surface of the intaglio printing plate. The vacuum chamber is arranged so that the intaglio printing plate to be coated sits substantially vertically in the inner space of the vacuum chamber with its engraved surface facing the at least one coating material target. The intaglio printing plate coating apparatus further comprises a movable carrier located within the inner space of the vacuum chamber and adapted to support and cyclically move the intaglio printing plate in front of and past the at least one coating material target.
Abstract:
There is described an ink wiping system (100; 100′; 100″) of an intaglio printing press comprising a wiping tank (101) and a rotatable wiping roller assembly (102; 102*) supported on and partly located in the wiping tank (101) for wiping excess ink from the surface of a rotatable intaglio printing cylinder (80) of the intaglio printing press. The ink wiping system (100; 100′; 100″) comprises a wiping roller retracting device (150) which forms an integral part of the ink wiping system (100; 100′; 100″) and is adapted to be coupled to the wiping roller assembly (102; 102*) to move the wiping roller assembly (102; 102*) between a working position (W) where the wiping roller assembly (102; 102*) is supported on and partly located in the wiping tank (101) for cooperation with the intaglio printing cylinder (80) and a parking position (P) where the wiping roller assembly (102; 102*) is retracted out of the wiping tank (101) and away from the intaglio printing cylinder (80). In the working position (W) of the wiping roller assembly (102; 102*), the wiping roller retracting device (150) is coupled to the wiping roller assembly (102; 102*). The ink wiping system (100; 100′; 100″) further includes, at the parking position (P), a storage section (110) adapted to receive the wiping roller assembly (102; 102*) which is retracted by the wiping roller retracting device (150).

Abstract:
There is described an intaglio printing plate coating apparatus (1) comprising a vacuum chamber (3) having an inner space (30) adapted to receive at least one intaglio printing plate (10) to be coated, a vacuum system (4) coupled to the vacuum chamber (3) adapted to create vacuum in the inner space (30) of the vacuum chamber (3), and a physical vapour deposition (PVD) system (5) adapted to perform deposition of wear-resistant coating material under vacuum onto an engraved surface (10a) of the intaglio printing plate (10), which physical vapour deposition system (5) includes at least one coating material target (51, 52) comprising a source of the wear-resistant coating material to be deposited onto the engraved surface (10a) of the intaglio printing plate (10). The vacuum chamber (3) is arranged so that the intaglio printing plate (10) to be coated sits substantially vertically in the inner space (30) of the vacuum chamber (3) with its engraved surface (10a) facing the at least one coating material target (51, 52). The intaglio printing plate coating apparatus (1) further comprises a movable carrier (6) located within the inner space (30) of the vacuum chamber (3) and adapted to support and cyclically move the intaglio printing plate (10) in front of and past the at least one coating material target (51, 52).
