摘要:
There is described a substrate (S) for security documents, such as banknotes, comprising one or more paper layers (11, 12) and a polymer layer (20) which is made to adhere to a side of at least one of the paper layers (11, 12), which polymer layer (20) is substantially transparent in at least one region of the substrate (S) which is not covered by the paper layer or layers (11, 12) so as to form a substantially transparent window (W) in the substrate (S) which is formed and closed by the polymer layer (20). The polymer layer (20) exhibits in the region of the window (W) a thickness (T) which is greater than a thickness (t) of the polymer layer (20) outside of the region of the window (W). The thickness (T) of the polymer layer (20) in the region of the window (W) is substantially equal to the added thickness of the paper layer or layers (11, 12) and of the polymer layer (20) outside of the region of the window (W) so that the substrate (S) exhibits a substantially uniform and constant thickness (T). The substrate (S) further comprises a micro-optical structure (30), in particular a lens structure, which is disposed in the region of the window (W) on at least one side of the polymer layer (20).

The system for an intaglio printing machine comprises at least a duct (1) for inking the surface of an engraved selective inking cylinder (5) which in turn inks the surface of a plate cylinder (16) of the intaglio printing machine via a chablon roller (17) having reliefs (18) corresponding to engravings (27) to be inked on said plate cylinder (16). Said inking system further comprises a wiping system (8) for wiping the surface of said selective inking cylinder and recuperating the wiped ink in the duct (1).

There is described a sheet-fed printing press for numbering and varnishing of security documents, especially banknotes, including: - a sheet-feeder (01) for feeding in succession printed material in the form of individual sheets carrying multiple security imprints ; - a numbering group (02) comprising at least one numbering unit (21, 22) for numbering the sheets ; - a varnishing group (03) located downstream of the numbering group (02) for applying varnish onto recto and verso sides of said sheets, the varnishing group (03) comprising at least a first varnishing unit (31) for applying varnish on the recto side of the sheets and at least a second varnishing unit (32) for applying varnish on the verso side of the sheets ; and - a sheet-delivery system (04) for collecting varnished sheets coming from the varnishing group (03), the numbering group (02) being coupled to the varnishing group (03) by means of an intermediate sheet gripper system (05) comprising space-apart gripper bars for holding the sheets by a leading edge of the sheets and transporting the sheets from the numbering group (02) to the varnishing group (03).
摘要:
Bogenverarbeitende Maschine zur Herstellung von Geldscheinen oder anderen Wertpapieren mit einer Mehrzahl von nacheinander gekoppelten Modulen zur Verarbeitung von Bogen, die mit einer Mehrzahl von in Spalten und Reihen angeordneten Nutzen versehen sind, umfassend : - ein Bogenanlagemodul (04) mit einem Bogenanleger (01) zum Zuführen einzelner Bogen ; - ein mit dem Bogenanlagemodul (04) gekoppelten Inspektionsmodul (31) zum Überwachen der Druckqualität der Bogen ; und - ein mit dem Inspektionsmodul (31) gekoppelten Nummeriermodul (08) zum Anbringen einer laufenden Nummerierung auf den Bogen,
wobei das Bogenanlagemodul (04), das Inspektionsmodul (31) und das Nummeriermodul (08) so gestaltet sind, dass das Inspektionsmodul (31) von den anderen Modulen abgekoppelt werden kann und eine Bogenannahmeschnittstelle (17) des Nummeriermoduls (08) an eine Bogenabgabeschnittstelle (07) des Bogenanlagemoduls (04) koppelbar ist.
摘要:
There is described a multicolour letterpress printing press, in particular a numbering press, comprising a printing group (50) with at least a first letterpress (e.g. numbering) cylinder (51) which is inked by an associated inking system (60, 71, 72, 81, 81 a, 81 b, 82, 82a, 82b). The inking system (60, 71, 72, 81, 81 a, 81 b, 82, 82a, 82b) comprises (i) a first inking device (81) supplying ink to a first chablon cylinder (71), (ii) at least a second inking device (82) supplying ink to a second chablon cylinder (72), and (iii) an ink-collecting cylinder (60) contacting the first and second chablon cylinders (71, 72) and collecting a first ink pattern (A, D) from the first chablon cylinder (71) and a second ink pattern (B, C) from the second chablon cylinder (72). As a result, a first multicolour pattern of inks (A-D) is formed on the ink-collecting cylinder (60), which first multicolour pattern of inks (A-D) is transferred onto the first letterpress cylinder (51).
