    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: The control element has a first drawing printed on a first side of the article, comprising at least a first set of geometrical shapes. It includes a second drawing printed on a second side of said article, the second drawing being printed so as to face the first drawing and be in register with the latter, said second drawing comprising at least a second set of geometrical shapes corresponding to the first screen. At least one of said geometrical sets includes sectors which are offset so that, when the front side/reverse side register is correct, the control element has regions of variable density which are visible in transmitted light and are created by said offset sectors.

    Abstract: There is described a method for controlling the position of numbering wheels (7) of a numbering device (1), which numbering device (1) is of the type comprising a plurality of independently-driven numbering wheels (7) disposed adjacent to one another for rotation about a common rotation axis, the method comprising actuating the numbering wheels (7) between successive numbering iterations, whereby each numbering wheel (7) which has to be rotated to a new target position is driven into rotation until it reaches its new target position. The method further comprises, at least during actuation of the numbering wheels (7), compensating for external factors acting on the numbering wheels (7), such as friction induced by adjacent rotating numbering wheels, by electronically regulating the position of each numbering wheel (7) which is not rotated or which has reached its new target position. Also described is a device for carrying out this method.
