Abstract:
There is described an inspection system (50) for in-line inspection of sheet-like or web-like material on an intaglio printing press, wherein the inspection system comprises an optical quality control apparatus for carrying out inspection of a printed area on a printed side of the sheet-like or web-like material, the optical quality control apparatus including a camera system (55) with at least one line-scan camera (56) for scanning and acquiring an image of the printed area while the sheet-like or web-like material is being transported in the intaglio printing press past the camera system (55). A location of the at least one line-scan camera (56) in the intaglio printing press along a delivery path of the sheet-like or web-like material is selected in such a way that cyclical vibrations that spread periodically throughout the intaglio printing press during operation of the intaglio printing press do not occur while the camera system (55) is scanning the printed area of the sheet-like or web-like material and acquiring a complete image of the printed area.
Abstract:
There is described an intaglio printing plate (1; 1*) for the production of banknotes and like printed securities, which intaglio printing plate comprises an engraved polymer layer (10) and wherein a surface of the engraved polymer layer is covered by one or more coatings (100; 200, 300) including an outer coating (100; 300) made of a wear-resistant material. The outer coating (100; 300) is preferably and advantageously formed by physical vapour deposition (PVD) of the wear-resistant material. Also described is a method of manufacturing the intaglio printing plate (1; 1*).
Abstract:
There is described a method for processing bundles (5) of securities, in particular banknote bundles, during production thereof, the method comprising the steps of (a) processing stacks of sheets (SS), each carrying an array of multiple security prints arranged in a matrix of rows and columns, into successive sets (2) of consecutive bundles (5) of securities arranged side-by-side, (b) forming at least one intermediate pile (8; 8*) of consecutive bundles (5) by placing the consecutive bundles (5) of a set (2) one on top of the other, and (c) successively ejecting bundles (5) one-by-one from a bottom of the said at least one intermediate pile (8; 8*) and conveying each ejected bundle (5) with a determined spacing from a preceding and/or following ejected bundle (5). There is also described a bundle processing system to carry out the above method.
Abstract:
There is described a numbering unit (6) of a numbering device (1), the numbering unit (6) comprising rotatable numbering wheels (7) carrying alpha-numerical symbols thereon, which numbering wheels (7) are disposed next to each other and rotate about a common rotation axis (17). The numbering unit (6) comprises a releasable indexing mechanism (50'; 7a', 510, 520) for mechanically aligning and maintaining the position of the numbering wheels (7) during a numbering operation, once the numbering wheels (7) have been rotated to their target positions. The releasable indexing mechanism (50'; 7a', 510, 520) comprises a movable indexing member (50'; 510) extending parallel to the rotation axis, which movable indexing member (50'; 510) is adapted to be pushed into indexing grooves (7a') provided on an inner periphery of the numbering wheels (7).
Abstract:
The machine comprises at least a plate cylinder (6) carrying printing plates with engravings corresponding to a specific intaglio structure to be printed, and cooperating with an impression cylinder (3), a collector cylinder (8) on which the ink in the different colours is deposited by selector cylinders (10), each selector cylinder (10) receiving ink of a given colour from a duct roller (11) and each selector cylinder (10) is driven by drive means (20,21,22) in an independent manner.
Abstract:
There is described a system and method for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate. The system comprises a processing unit (10*) with at least one magnetic-field-inducing device for orienting the magnetic flakes contained in the ink or varnish vehicle applied on the substrate, which processing unit (10*) is located along a path of the substrate in such a way that the substrate is brought into contact with or in close proximity to the processing unit (10*) and the at least one magnetic-field-inducing device. The system further comprises at least one drying or curing unit (60) disposed in the vicinity of the processing unit (10*) for drying or curing the ink or varnish vehicle to fix the orientation of the magnetic flakes contained therein while the substrate is still in contact with or in close proximity to the processing unit (10*) and the at least one magnetic-field-inducing device before the substrate is taken away from the at least one magnetic-field-inducing device.
Abstract:
There is described a method for processing stacks (1) of sheets of securities, especially banknotes, into bundles (3) and bundle packs (4), said sheets each having an array of security prints printed thereon which array comprises M columns and N rows. According to this method, each stack (1) of sheets is processed into M successive bundle groups (3*) of N individual bundles (3) each and these M successive bundle groups (3*) are stored in M separate storage areas (11), which storage areas (11) are vertically superposed, whereby each one of the M successive bundle groups (3*) is stored in a predetermined one of the M separate storage areas (11). Subsequent stacks (1) of sheets are processed, whereby each one of the M successive bundle groups (3*) processed from said subsequent stacks (1 ) of sheets is piled in the same predetermined one of said M separate storage areas (11) as the first stack (1) of sheets. When K stacks (1) of sheets have been processed, each storage area (11) contains a complete set (4*) of N bundle packs (4) of K bundles (3) each. There is also described a bundle collating system (10) for collecting the bundles (3) processed according to the above collating method.
Abstract:
There is described process for producing security papers, in particular banknotes, comprising the step of sealing the surface of the security papers by applying a protective pattern on the surface of the security paper, which sealing comprising printing the security papers by intaglio printing using an intaglio printing plate with engraved areas such that at least 80% of the whole surface of each security paper is covered with embossed intaglio patterns produced by engraved areas of the intaglio printing plate which are inked or with a combination of embossed intaglio patterns and flat intaglio patterns, which flat intaglio patterns are produced by unengraved areas of the intaglio printing plate which are inked after wiping of the intaglio printing plate, at least a part of the embossed intaglio patterns and/or flat intaglio patterns being printed with a transparent or semi-transparent intaglio ink. The transparent or semi-transparent intaglio ink is applied in engraved areas and/or unengraved areas of the intaglio printing plate so as to seal substantially the whole surface of the security papers with a protective pattern composed of intaglio patterns. Also described are intaglio printing presses for implementing the said process and the resulting security papers.
