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.

Printing press with in-line casting device for the replication and formation of a micro-optical structure

A printing press and a method for producing security products or security intermediate products comprises a feed device for feeding unprinted printing substrate into the printing press. Multiple printing couples print the unprinted printing substrate in an indirect planographic or in a letterpress printing method in one or more printing nips. In a conveyor line, between the feed device and the first printing nip located in the printing substrate path, at least one inspection device, which is embodied as a transmissive inspection device, is provided for inspecting the as yet unprinted printing substrate.

Printing press and method for producing security products or security intermediate products

There is described a printing press (****) 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 (****) designed to print a first side (I) and/or a second side (II) of the substrate (S). 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 printing sheets of printing substrate (), having a first printing nip () which is formed between a first cylinder (*) that acts as a transport cylinder (*) and a second cylinder (), and in which the printing substrate sheets () can be printed on one or on both sides with one or more collected print image segments, and having a second printing nip () lying downstream in the printing substrate path, which printing nip is disposed at a level lying below the first printing nip () and is formed between a third cylinder () that acts as a transport cylinder () and a fourth cylinder (), and in which the printing substrate sheets () can be printed on one or on both sides with one or more collected print image segments, wherein the printing substrate sheets () can be conveyed via at least one rotating transport means () along a transport path from the cylinder (*) that acts as a transport cylinder (*) of the first printing nip () to the cylinder () that acts as a transport cylinder () of the second printing nip (), wherein on the transport path, downstream of the cylinder (*) that acts as a transport cylinder (*) of the first printing nip () and upstream of the cylinder () that acts as a transport cylinder () of the second printing nip (), at least one first electrode () directed toward the outer circumference of the at least one rotating transport means () is arranged in an angular segment lying in the transport path for the printing substrate sheets () in such a way that when an electric voltage is applied, a printing substrate sheet () being guided past the electrode () can be electrostatically charged.

Device, method and printing press for multiple printing of printing substrate sheets

There is described an intaglio printing press (*) comprising a plate cylinder () carrying one or more intaglio printing plates, the plate cylinder () receiving ink from an inking system (*) having a plurality of chablon cylinders (*) transferring ink directly or indirectly onto the plate cylinder (), the intaglio printing press (*) comprising an adjustment system acting on the chablon cylinders (*) in order to compensate elongation of the one or more intaglio printing plates. The adjustment system comprises, for each chablon cylinder (*), an adjustable drive unit, which adjustable drive unit () is interposed between the chablon cylinder (*) acting as a rotating output body of the adjustable drive unit () and a driving gear () acting as a rotating input body of the adjustable drive unit (). The adjustable drive unit () is designed to allow selected adjustment of a rotational speed of the chablon cylinder (*) with respect to a rotational speed of the driving gear (). In an adjusting state of the adjustable drive unit (), driving into rotation of the chablon cylinder (*) is adjusted over each revolution of the chablon cylinder (*) by means of an adjustment motor () of the adjustable drive unit (). In a non-adjusting state of the adjustable drive unit (), the adjustment motor () is inoperative and driving into rotation of the chablon cylinder (*) is performed exclusively mechanically via the adjustable drive unit (), the chablon cylinder (*) rotating at a same rotational speed as the driving gear ().

Intaglio printing press

There is described an intaglio printing press (*) comprising an intaglio cylinder () and an ink wiping system () with a rotating wiping roller assembly () contacting a circumference of the intaglio cylinder () for wiping excess ink from the surface of the intaglio cylinder (), a rotational speed of the wiping cylinder being adjustable with respect to a rotational speed of the intaglio cylinder (). The intaglio printing press (*) comprises an adjustable drive unit (), which adjustable drive unit () is interposed between the wiping roller assembly () acting as a rotating output body of the adjustable drive unit () and a driving gear () coupled to the intaglio cylinder () and acting as a rotating input body of the adjustable drive unit (). The adjustable drive unit () is designed to allow selected adjustment of a rotational speed of the wiping roller assembly () with respect to a rotational speed of the driving gear (). In an adjusting state of the adjustable drive unit (), driving into rotation of the wiping roller assembly () is adjusted by means of an adjustment motor () of the adjustable drive unit (). In a non-adjusting state of the adjustable drive unit (), the adjustment motor () is inoperative and driving into rotation of the wiping roller assembly () is performed exclusively mechanically via the adjustable drive unit (), the wiping roller assembly () rotating at a defined rotational speed with respect to the rotational speed of the intaglio cylinder ().
