Abstract:
There is described a sheet-fed or web-fed printing press for numbering and varnishing of security documents, including banknotes, comprising: —a numbering group (02) comprising at least one numbering unit (21, 22) for numbering printed material in the form of individual sheets or successive portions of a continuous web carrying multiple security imprints; and—a varnishing group (03; 03*) located downstream of the numbering group (02) for applying varnish onto recto and verso sides of the printed material, the varnishing group (03; 03*) comprising at least a first varnishing unit (31) disposed above a path of the printed material to apply varnish on the recto side of the printed material and at least a second varnishing unit (32) disposed below the path of the printed material to apply varnish on the verso side of the printed material.
Abstract:
There is described a method for applying foil material (200) onto successive sheets (S), especially sheets of securities. In a first step, individual sheets (S) are transported in succession along a sheet transport path. In a second step, at least one continuous band of foil material (200) is applied onto the individual sheets (S) along a direction substantially parallel to a direction of displacement of the individual sheets, thereby forming a continuous flow of sheets linked to one another by the said at least one continuous band of foil material (200). In a third step, the said at least one continuous band of foil material (200) is cut by means of a laser beam such that the continuous flow of sheets is again separated into individual sheets (S) with portions of foil material (200*) remaining on the sheet. The cutting is performed at positions located on the sheets (S) such that said portions of foil material (200*) remaining on the sheets do not extend beyond leading and trailing edges of the sheets (S). Waste portions (205) of said at least one continuous band of foil material (200) that are not to remain on the sheets (S) are evacuated by aspiration, evacuation being carried out by direct aspiration of the waste portions (205) at least at a first position located downstream of and proximate to a cutting position where said at least one continuous band of foil material (200) is cut by the laser beam. There is also described an installation for carrying out the above method.
Abstract:
The printing machine comprises at least one transfer system for conveying a substrate onto an impression cylinder and at least one screen of cylindrical or flat shape, with a doctor blade, said screen collaborating with the impression cylinder and intended to print the substrate with an ink containing pigments that can be orientated by a magnetic field and an unloading system for carrying the substrate away. The impression cylinder comprises at least one magnetic element on its impression surface, said magnetic element being positioned at a point corresponding to said impression performed by said screen on said substrate.
Abstract:
There is described a method for applying foil material (200) onto successive sheets (S), especially sheets for the production of securities, such as banknotes. In a first step, individual sheets (S) are transported in succession along a sheet transport path. In a second step, at least one continuous band of foil material (200) is applied onto the individual sheets (S) along a direction substantially parallel to a direction of displacement (A) of the individual sheets, thereby forming a continuous flow of sheets linked to one another by the said at least one continuous band of foil material (200). In a third step, the said at least one continuous band of foil material (200) is cut by means of a laser beam (L) such that the continuous flow of sheets is again separated into individual sheets (S) with portions of foil material (200*) remaining on the sheet. The cutting is performed at positions located on the sheets (S) such that said portions of foil material (200*) remaining on the sheets do not extend beyond leading and trailing edges of the sheets (S). Waste portions (205) of said at least one continuous band of foil material (200) that are not to remain on the sheets (S) are seized prior to cutting by the laser beam (L) and are held throughout the cutting process. There is also described an installation for carrying out the above method.

Abstract:
The invention concerns a method for printing security documents (1) comprising in particular a lacquering step which consists in depositing a protective layer on the surface of the security documents, as well as a typographic printing step which consists in printing at least one typographic element (4) on said security documents following the lacquering step. Therefor, prior to the typographic printing step, at least one roughened surface (3) is formed on the security documents, for receiving a typographic element. The roughness of the surface (4) provides better adherence of the typographic ink on the documents already provided with a protective coating produced, for example, with a UV-curable lacquer.
Abstract:
A cylinder for stamping planar substrates, such as sheets of paper comprises at least a pit with clamping means for holding a stamping medium on said cylinder, said medium comprising at least a row of stamps distributed along the medium. The medium is formed by a stamping plate or by stamping strips and said cylinder further comprises at least a supporting piece forming a bridge over said pit.

Abstract:
There is described a method for processing stacks of sheets (SS) into bundles (5) of securities, in particular banknote bundles, the method comprising the steps of cutting successive stacks of sheets (SS), each carrying an array of multiple security prints arranged in a matrix of rows and columns, into successive sets of bundle strips (S; S*), and cutting the successive set of bundle strips (S; S*) into successive sets (2) of consecutive bundles (5) of securities. This method further comprises the step of counting the number of substrates within each bundle strip (S; S*) prior to cutting thereof into the successive sets (2) of consecutive bundles (5). Such counting comprises taking at least one image (I) of a at least a portion of a longitudinal side (10) of the bundle strip (S; S*) while the bundle strip (S; S*) is being displaced along a direction of displacement (A) which is parallel to the longitudinal side (10) of the bundle strips (S; S*), and processing the said at least one image (I) to derive a substrate count of the substrates within the bundle strip (S; S*). Also described in a system for carrying out this method.
