    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: 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 printing press (100) comprising a printing group (2) adapted to apply on a substrate at least one ink or varnish vehicle containing magnetic or magnetisable flakes and at least one magnetic orientation unit (10) located downstream of the printing group (2) along a path of the substrate, which magnetic orientation unit (10) includes at least one magnetic-field-inducing device (12) adapted to orient the magnetic or magnetisable flakes contained in the ink or varnish vehicle applied on the substrate to induce an optically-variable effect in the ink or varnish vehicle. The printing press (100) further comprises a drying/curing unit (15) located along the path of the substrate and cooperating with the magnetic orientation unit (10), which drying/curing unit (15) is adapted to dry or cure the ink or varnish vehicle applied on the substrate following orientation of the magnetic or magnetisable flakes. The drying/curing unit (15) is mounted on a movable supporting structure (16) that is adapted to move the drying/curing unit (15) between a working position (WP), where the drying/curing unit (15) is cooperating with the magnetic orientation unit (10) and which is located proximate to the path of the substrate next to the magnetic orientation unit (10), and a retracted position (RP), where the drying/curing unit (15) is retracted away from the magnetic orientation unit (10) and from the path of the substrate.

    Abstract: There is described a new coding approach for printed document authentication, one objective of which is to increase the difficulty of copying. In addition, this new coding approach provides better performance compared to other 2D coding technolo gies under certain constraints. The new coding technique requires less print space in comparison to other coding techniques. This is achieved by optimising some of the features which are used in standard 2D-codes for stabilisation and which are necessary for e.g. mobile applications. Furthermore, the code can be decomposed in elementary units, or “byte-units” which can be widely spread over a text document. Such “byte-units” can in particular be used for integration in text symbols. If a document protected with such a coding is copied, at least some of these symbols will be extensively degraded by the copying process. Therefore, copy detection is intrinsically achieved thanks to the new coding technique.

    Abstract translation: 描述了用于打印文件认证的新的编码方法，其目的是增加复制的难度。 此外，与其他2D编码技术相比，这种新的编码方法在某些限制下提供了更好的性能。 与其他编码技术相比，新的编码技术需要更少的打印空间。 这通过优化用于稳定化的标准2D代码中的一些特征来实现，并且对于例如， 移动应用。 此外，代码可以以基本单位分解，或者可以广泛分布在文本文档上的“字节单位”。 这样的“字节单位”可以特别地用于集成在文本符号中。 如果复制了用这种编码保护的文档，则这些符号中的至少一些将被复制过程广泛地降级。 因此，通过新的编码技术，本质上实现了拷贝检测。
