摘要： An inking system for inking an intaglio printing cylinder of an intaglio printing press is designed to perform a selective transfer of ink to one or more intaglio printing mediums by way of a selective inking cylinder provided in at least one device. The selective inking cylinder carries a selective inking plate that receives ink supplied by an associated inking unit. The selective inking plate comprises a coating that is selectively structured to exhibit ink-repellent portions and perform selective transfer of ink at locations 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 is performed indirectly from the selective inking cylinder to the one or more intaglio printing mediums via an ink collecting cylinder and/or via a chablon cylinder carrying a chablon plate.

摘要： There is described a printing press (100***; 100****) adapted to carry out printing on a sheet-like or web-like substrate (S), in particular for the production of security documents such as banknotes, comprising a printing unit (2*; 2**; 2***; 2****) designed to print a first side (I) and/or a second side (II) of the substrate (S). The printing press (100***; 100****) further comprises an in-line casting device (80; 80*; 80**; 80***) adapted to apply a layer of material acting as an optical medium on a portion of a first side (I, II) of the substrate (S) and to replicate and form a micro-optical structure (L) in the layer of material acting as optical medium. The printing unit (2*; 2**; 2***; 2****) is furthermore adapted to print at least one printed pattern on the first or second side (I, II) of the substrate (S) in register with the micro-optical structure (L), wherein the printing unit (2*; 2**; 2***; 2****) comprises at least a first printing group (93) being adapted to print at least one printed pattern on the second side (II) of the substrate (S) in register with the micro-optical structure (L) and wherein the in-line casting device (80; 80*; 80**; 80***) comprises at least one embossing cylinder (85), which embossing cylinder (85) also is acting as counter-pressure cylinder and cooperates with a printing cylinder (8) of the at least first printing group (93) and/or whereas the in-line casting device (80; 80*; 80**; 80***) and the at least a first printing group (93) being arranged at the Substrate transport path such way, that in-line casting of the micro-optical structure, on one side of the sheets S, and printing of the associated pattern, on the other side of the sheets S, are performed in a same step, without this involving any sheet transfer operation.

摘要： There is described a printing press adapted to carry out printing on a sheet-like or web-like substrate, in particular for the production of security documents such as banknotes, comprising a substrate feeding device for feeding the substrate to be treated, at least a printing unit designed to print a first side and/or a second side of the substrate and a delivery unit for receiving the treated substrate. The printing press in the conveying path for the substrate between the feeding device and the delivery unit further comprises an in-line casting device adapted to apply a layer of material acting as an optical medium on a portion of the second side of the substrate and to replicate and form a micro-optical structure in the layer of material acting as optical medium, wherein the printing unit comprises a first printing group comprising a printing cylinder and being adapted to print at least one printed pattern on the first or second side of the substrate in register with the micro-optical structure.

摘要： There is described a hot-stamping press (10; 10″; 10′″) comprising a foil application unit (2; 2*) designed to allow transfer or lamination of foil material (FM) by hot-stamping onto a substrate (S) supplied in the form of successive sheets or successive portions of a continuous web, which foil material (FM) is fed to the foil application unit (2; 2*) in the form of a foil carrier (FC) supplied by means of a foil feeding system (3). The hot-stamping press (10; 10″; 10′″) further comprises at least one UV-curing unit (61; 62; 63) located along a path (A) of the substrate (S) downstream of the foil application unit (2; 2*) to subject the foil material (FM) transferred or laminated onto the substrate (S) to a UV-curing operation. The foil material (FM) is provided with an adhesive intended to ensure adhesion of the foil material (FM) onto the substrate (S), which adhesive comprises a combination of hot-melt compounds reacting to the application of heat produced by the foil application unit (2; 2*) and UV-curing compounds reacting to the application of ultraviolet radiation produced by the UV-curing unit (61; 62; 63).
