    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).

    Abstract: There are described various embodiments of an inking system for inking an intaglio printing cylinder (8) of an intaglio printing press (1I; 1II; 1III ; 1IV; 1V), which intaglio printing cylinder carries one or more intaglio printing mediums (8a, 8b, 8c) that are inked by means of a plurality of inking devices (95; 95*; 95**; 905; 905*). The inking system is designed to perform a selective transfer of ink to the one or more intaglio printing mediums by means of a selective inking cylinder (98; 98*; 98**) provided in at least one of the inking devices, preferably in each of the inking devices. More precisely, the selective inking cylinder carries a selective inking plate (90a) receiving ink supplied by an associated inking unit (96/96a/97; 96*/96a*/97*; 96**/96a**; 906/906a/910/915; 906*/906a*/910*/915*), which selective inking plate comprises a coating (900) that is selectively structured to exhibit ink-repellent portions (910) and perform selective transfer of ink at locations (920) 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 to the one or more intaglio printing mediums is performed indirectly from the selective inking cylinder to the one or more intaglio printing mediums via an ink collecting cylinder (9) and/or via a chablon cylinder (99*; 99**) carrying a chablon plate (99a) comprising relief portions (99A) 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.
