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:
The invention relates to a method for transferring a decorative section (16) of an embossing foil (1) to a substrate (23) by means of an embossing roller (24), an embossing stamp (24'), or an applied adhesive layer (14). The embossing foil (1) comprises a carrier foil (11) and a transfer layer (13) arranged on the carrier foil (11). The method comprises providing the embossing foil (1), stamping at least one linear notch (15) arranged at a distance from the edge of the decorative section (16) into the transfer layer (13), embossing the decorative section (16) onto the substrate (23), and detaching the remaining embossing foil from the substrate (25) embossed with the decorative section (16).
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.

Abstract:
There is described a sheet-fed or web-fed screen printing press, especially for the production of banknotes and like securities, comprising an impression cylinder (2a), a first screen printing unit (2b) cooperating with the impression cylinder (2a) for applying a first ink pattern (A) onto successive sheets or web portions, at least a second screen printing unit (2c) cooperating with the impression cylinder (2a) for applying a second ink pattern (B) onto the successive sheets or web portions, which second screen printing unit (2c) is located downstream of the first screen printing unit (2b) with respect to a direction of rotation of the impression cylinder (2a), and an intermediate drying unit (10) located between the first and second screen printing units (2b, 2c). The intermediate drying unit (10) is adapted to perform superficial drying of the first ink pattern (A) applied by the first screen printing unit (2b) before application of the second ink pattern (B) by the second screen printing unit (2c), which superficial drying involves only the drying of an outer superficial portion (S) of the first ink pattern (A). Preferably, the second screen printing unit (2c) is adapted to apply the second ink pattern (B) in close proximity to the first ink pattern (A) or at least in a partially overlapping manner onto the first ink pattern (A).
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.
