Claim 0:
1. An intaglio gravure printing press comprising at least one gravure printing unit, the at least one gravure printing unit comprising at least one forme cylinder (03), at least one impression cylinder (01), and at least one inking unit (18), wherein:
the at least one inking unit (18) is arranged at the at least one forme cylinder (03) and provides ink to the at least one forme cylinder (03), or
at least one ink collecting cylinder (12) is arranged at the at least one forme cylinder (03) and the at least one inking unit (18) is arranged at the at least one ink collecting cylinder (12), the at least one ink collecting cylinder (12) providing ink from the inking unit (18) to the at least one forme cylinder (03),
the intaglio gravure printing press further comprising at least one print head (04), which is arranged at the at least one forme cylinder (03), and which is positioned with respect to the at least one forme cylinder (03) to apply a protective fluid into at least one engraving on the at least one forme cylinder (03) prior to the ink being applied into the at least one engraving on the at least one forme cylinder (03) to enable the at least one forme cylinder (03) to deposit concurrently both the ink and the protective fluid during printing onto at least one substrate (10), the protective fluid forming a protective layer and/or protective film on the ink deposited onto the at least one substrate (10), the protective fluid configured to at least one of dry, be dried, cure, or be cured more quickly than the ink,
the intaglio gravure printing press further comprising at least one wiping device (05) arranged at the at least one forme cylinder (03), wherein the at least one wiping device (05) is arranged along the direction of rotation of the at least one forme cylinder (03), downstream from the at least one print head (04), and upstream from a contact region of the at least one forme cylinder (03) with the at least one impression cylinder (01), and
the intaglio gravure printing press further comprising at least one dryer (07) arranged along a transport path of the at least one substrate (10), downstream from the at least one forme cylinder (03) and upstream from at least one collecting position of the at least one substrate (10), the at least one dryer (07) configured to dry and/or cure, at least in part, the protective fluid.
