Abstract:
It is especially described a control process for intaglio printing, in particular for printing paper securities, such as banknotes. This control process includes defining on an intaglio printing plate (80) control areas (150, 151-155; 170, 171-179) designed in such a manner as to allow in particular evaluation of effects of the printing pressure applied during printing of a substrate by means of the intaglio printing plate (80) and evaluation of effects of the ink coverage applied during inking of the intaglio printing plate (80), which control areas (150, 151-155; 170, 171-179) are engraved in a portion of the intaglio printing plate (80) in order to produce corresponding printed control zones (160, 161-165) on the substrate. The process further includes carrying out of measurements in the printed control zones allowing evaluation of the printing pressure applied during printing of the substrate as well as of the ink coverage applied during inking of the intaglio printing plate (80).
Abstract:
There is described a printing press (1; 1*; 1**) comprising an ink-receiving cylinder (9; 8) receiving ink from an inking system (90-93, 90*, 93*; 95-99, 95*, 99*; 100-104, 100*, 104*) having a plurality of ink-applying cylinders or rollers (93, 93*; 99, 99*; 104, 104*) arranged one above the other around part of a circumference of the ink-receiving cylinder (9; 8), the ink-applying cylinders or rollers (93, 93*; 99, 99*; 104, 104*) being inked by a corresponding plurality of inking devices (90, 90*; 95, 95*; 100, 100*), the printing press (1; 1*; 1**) further comprising an inking carriage (52; 55; 57) supporting the plurality of inking devices (90, 90*; 95, 95*; 100, 100*), which inking carriage (52; 55; 57) can be moved with respect to the ink-receiving cylinder (9; 8) between a working position and a retracted position. The at least one selected inking device (90*; 95*; 100*) amongst the plurality of inking devices (90, 90*; 95, 95*; 100, 100*) of the inking system (90-93, 90*, 93*; 95-99, 95*, 99*; 100-104, 100*, 104*) is supported onto the inking carriage (52; 55; 57) via a movable frame (60; 65; 70), which movable frame (60; 65; 70) is supported by the inking carriage (52; 55; 57) to allow movement of the selected inking device (90*; 95*; 100*) with respect to the inking carriage (52; 55; 57) and with respect to a remaining part (90; 95; 100) of the plurality of inking devices (90, 90*; 95, 95*; 100, 100*).
Abstract:
Intaglio printing press systems for recto-verso intaglio printing of sheets, in particular for the production of banknotes and the like securities, wherein first and second intaglio printing presses are operatively-coupled to one another by a sheet processing and transporting system comprising an automated guided vehicle system for automatically transporting sheets from a sheet delivery station of the first intaglio printing press where recto printing is performed to a sheet feeding station of the second intaglio printing press where verso printing is performed.
Abstract:
There is described an intaglio printing press (1; 1*) comprising a plate cylinder (8) carrying one or more intaglio printing plates, the plate cylinder (8) receiving ink from an inking system (9, 20, 23; 20*, 23*) having a plurality of chablon cylinders (23; 23*) transferring ink directly or indirectly onto the plate cylinder (8), the intaglio printing press (1; 1*) comprising an adjustment system acting on the chablon cylinders (23; 23*) in order to compensate elongation of the one or more intaglio printing plates. The adjustment system comprises, for each chablon cylinder (23; 23*), an adjustable drive unit, which adjustable drive unit (25) is interposed between the chablon cylinder (23; 23*) acting as a rotating output body of the adjustable drive unit (25) and a driving gear (100) acting as a rotating input body of the adjustable drive unit (25). The adjustable drive unit (25) is designed to allow selected adjustment of a rotational speed of the chablon cylinder (23; 23*) with respect to a rotational speed of the driving gear (100). In an adjusting state of the adjustable drive unit (25), driving into rotation of the chablon cylinder (23; 23*) is adjusted over each revolution of the chablon cylinder (23; 23*) by means of an adjustment motor (300) of the adjustable drive unit (25). In a non-adjusting state of the adjustable drive unit (25), the adjustment motor (300) is inoperative and driving into rotation of the chablon cylinder (23; 23*) is performed exclusively mechanically via the adjustable drive unit (25), the chablon cylinder (23; 23*) rotating at a same rotational speed as the driving gear (100).

There is described a cylinder body (10) for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate, which cylinder body (10) has a plurality of magnetic-field-generating devices (50, 60) disposed on an outer circumference of the cylinder body (10). The cylinder body (10) comprises a plurality of distinct annular supporting rings (40) distributed axially along a common shaft member (20), each annular supporting ring (40) carrying a set of magnetic-field-generating devices (50, 60) which are distributed circumferentially on an outer circumference of the annular supporting rings (40).
Abstract:
A sheet-processing machine comprises a plurality of modules which are passed through one after the other by the sheets to be processed. The modules each have a sheet input interface and/or a sheet output interface, wherein, in at least one of the modules, the sheet input interface and/or the sheet output interface can optionally be coupled to sheet output interfaces and sheet input interfaces, respectively, of at least two other modules.
