A method is provided for producing banknotes, which include, in each case, at least one integrated circuit. The banknotes are produced from a sheet or from a material web in a production panel. In at least a plurality of these banknotes, or in each of these banknotes, an aperture is created through their substrate. In each case, an integrated circuit is arranged in the relevant aperture. In a first method step, each of the integrated circuits to be arranged in one of the apertures is arranged, with respect to the intended position in each of the banknotes that include an aperture, in the correct position on a band-shaped foil, and, in the second method step, each of these integrated circuits is transferred from this band-shaped foil onto the relevant banknote. Owing to this transfer carried out in the second method step, one integrated circuit in each case, is arranged in the aperture created in the banknotes.

Method for producing banknotes including in each case at least one integrated circuit

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.

There is described a hot-stamping press ('&#x2033;) comprising a foil application unit (*) 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 (*) in the form of a foil carrier (FC) supplied by means of a foil feeding system (). The hot-stamping press () further comprises at least one UV-curing unit () located along a path (A) of the substrate (S) downstream of the foil application unit (*) 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 (*) and UV-curing compounds reacting to the application of ultraviolet radiation produced by the UV-curing unit ().

The printing press (****) further comprises an in-line casting device (***) 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 (****) 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 (****) comprises at least a first printing group () 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 (***) comprises at least one embossing cylinder (), which embossing cylinder () also is acting as counter-pressure cylinder and cooperates with a printing cylinder () of the at least first printing group () and/or whereas the in-line casting device (***) and the at least a first printing group () 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.

The invention relates to a device for producing security elements () on a substrate (), said device having a first printing couple (), by means of which substrate () being conveyed along a transport path is and/or can be printed with a plurality of first print image elements () spaced apart from one another using a first coating medium () that contains magnetic particles; a first magnetic cylinder (), arranged downstream of the first printing couple () in the transport path and comprising magnetic elements () on its outer circumference; a second magnetic cylinder (), arranged downstream of the first magnetic cylinder () in the transport path and likewise comprising magnetic elements () on its outer circumference; and a drying and/or curing device (), associated with or positioned downstream of the second magnetic cylinder () in the transport path, by means of which at least the coating medium () of a plurality of second print image elements (), printed onto the substrate () and spaced apart from one another, is and/or can be dried and/or cured at least superficially and/or at least each partially, wherein in the transport path between the first and the second magnetic cylinder () a second printing couple () is provided, by means of which the substrate () is and/or can be printed with the spaced-apart second print image elements () using the second coating medium () that contains magnetic particles, and wherein a drying and/or curing device () positioned upstream of the second printing couple () is associated with or positioned downstream of the first magnetic cylinder () in the transport path, by means of which device the coating medium () containing magnetic particles of the first print image elements () printed by the first printing couple () is and/or can be dried and/or cured at least superficially and/or at least each partially.

Device and printing press for producing a security element on a substrate

There is described a security element (EL) or document (BN), such as a banknote, comprising (i) a substrate (S) with first and second sides (I, II) and exhibiting at least one window region (W) made of a substantially transparent material, (ii) a micro-optical structure (OP) provided on the first side (I) of the substrate (S) and extending over at least a part of the window region (W), and (iii) a printed feature (P-P) printed on the second side (II) of the substrate (S) over at least a part of the window region (W), the printed feature (P-P) being provided in register with the micro-optical structure (OP) to produce an optically-variable effect (EF) upon looking at the printed feature (P-P) from the first side (I) of the substrate (S) through the micro-optical structure (OP) and the window region (W).
