Summary:There are described various embodiments of an inking system for inking an intaglio printing cylinder (8) of an intaglio printing press (1 I ; 1 II ; 1 III ; 1 IV ; 1 V ), 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.
