Abstract: An inking system for inking an intaglio printing cylinder of an intaglio printing press is designed to perform a selective transfer of ink to one or more intaglio printing mediums by way of a selective inking cylinder provided in at least one device. The selective inking cylinder carries a selective inking plate that receives ink supplied by an associated inking unit. The selective inking plate comprises a coating that is selectively structured to exhibit ink-repellent portions and perform selective transfer of ink at locations corresponding to engraved areas of the one or more intaglio printing mediums that are to be inked with the ink supplied by the associated inking unit. The selective transfer of ink is performed indirectly from the selective inking cylinder to the one or more intaglio printing mediums via an ink collecting cylinder and/or via a chablon cylinder carrying a chablon plate.

Abstract: There is described an inking apparatus of a printing press, in particular an offset or letterpress printing press, comprising at least one ink duct (11, 12) with an ink supply roller (13, 14), an ink roller train (30) comprising at least one inking roller (31) which receives ink from the at least one ink duct (11, 12), and at least one vibrator roller (15, 16) interposed between the ink supply roller (13, 4) and the inking roller (31), which vibrator roller (15, 16) is swung back and forth between the ink supply roller (13, 14) and the inking roller (31) and intermittently transfers ink from the ink supply roller (13, 14) to the inking roller (31). A circumference of the vibrator roller (15, 16) exhibits an ink-transfer 10 structure (15a, 16a) which reflects a desired inking profile of a printing plate to be inked by the inking apparatus and is designed to modulate a quantity of ink transferred by the vibrator roller (15, 16). The ink-transfer structure (15a, 16a) on the circumference of the vibrator roller (15, 16) is subdivided, in a circumferential direction (y) of the vibrator roller (15, 16), into an integer number 1 (r) of individual ink-transfer portions (15b, 16b) that are repeated with a determined circumferential period (Δy) in the circumferential direction (y), each individual ink-transfer portion (15b, 16b) reflecting the desired inking profile of the printing plate to be inked by the inking apparatus. A contact length (CL) over which the vibrator roller (15, 16) runs in contact with the ink supply roller (13, 204) is equivalent to the determined circumferential period (Δy) of the individual ink-transfer portions (15b, 16b) or to an integer multiple of the determined circumferential period (Δy) of the individual ink-transfer portions (15b, 16b).

Abstract: There is described a recto-verso printing press (100*) adapted to carry out simultaneous recto-verso printing of sheets, the printing press (100*) comprising a main printing group (5, 6, 15, 16, 25, 26) with first and second printing cylinders (5, 6) cooperating with one another to form a first printing nip between the first and second printing cylinders (5, 6) where first and second sides of sheets are simultaneously printed, the first printing cylinder (5) acting as a sheet conveying cylinder of the main printing group (5, 6, 15, 16, 25, 26). The printing press (100*) further comprises an additional printing group (7, 8, 17, 18, 27, 28) with third and fourth printing cylinders (7, 8) cooperating with one another to form a second printing nip between the third and fourth printing cylinders (7, 8) where the first and second sides of the sheets are simultaneously printed, the third printing cylinder (7) acting as a sheet conveying cylinder of the additional printing group (7, 8, 17, 18, 27, 28). The main printing group (5, 6, 15, 16, 25, 26) and the additional printing group (7, 8, 7, 18, 27, 28) are coupled to one another by means of an intermediate sheet conveying system comprising one or more sheet-transfer cylinders (10, 10′, 10″)interposed between the first and third printing cylinders (5, 7).

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: A method of authenticating security documents and a mobile device, especially a smartphone, programmed to carry out the method, based on an analysis of features which are produced by intaglio printing, which analysis involves a decomposition of sample images of a candidate document to be authenticated based on Wavelets, each sample image being digitally processed by performing a Wavelet transform of the sample image in order to derive a set of classification features. The method is based on an adaptive approach, which includes the following steps: —prior to carrying out the Wavelet transform, defining a categorization map containing local information about different intaglio line structures that are found on the security documents; —carrying out a Wavelet selection amongst a pool of Wavelet types based on the categorization map; and —performing the Wavelet transform of the sample image on the basis of the selected Wavelet.

Abstract: There is described a sheet numbering process involving feeding of individual sheets (S) in succession, which individual sheets (S) each carry a plurality of imprints (P) that are arranged in a matrix of rows and columns, and providing unique serial numbers to multiple ones of the plurality of imprints (P) carried by the individual sheets (S). The sheet numbering process comprises numbering of at least some of the individual sheets (S), wherein numbering of the individual sheets (S) is selectively commutable between a first numbering scheme (N1) and at least a second numbering scheme (N2; N2′; N*), different from the first numbering scheme (N1), without interruption of the numbering process. The first numbering scheme (N1) involves providing all imprints (P) of a first subset (S0) of individual sheets (S) with a unique serial number (SN1) of the first numbering scheme (N1). The second numbering scheme (N2; N2′; N*) involves providing all or part of the imprints (P) of a second subset (S′; S*) of individual sheets (S) with a unique serial number (SN2; SN2′; SN*) of the second numbering scheme (N2; N2′; N*). The first subset (S0) of individual sheets (S) and the second subset (S′; S*) of individual sheets are sorted after numbering in dependence of the numbering scheme (N1; N2; N2′; N*). Also described is a sheet-processing machine for carrying out the aforementioned sheet numbering process.

Abstract: There is described a method for manufacturing intaglio printing plates for the production of security papers, wherein a laser beam (2) is used to engrave intaglio printing patterns (3, 3.1, 3.2, 3.3) directly into the surface of a laser-engravable, especially metallic, printing plate medium (1), wherein laser engraving of the printing plate medium (1) is carried out layer by layer in several individual engraving steps performed one after the other in register so that the intaglio printing patterns (3, 3.1, 3.2, 3.3) are gradually engraved into the surface of the printing plate medium (1) up to desired engraving depths, the surface of the engraved printing plate medium (1) being cleaned from residues of the laser engraving process following and between each individual engraving step.
