A sheet-fed printing machine comprises two sheet-fed printing units; of which a first is configured as a sheet-fed simultaneous printing unit and has two collector cylinders, which interact with one another and each have an axis of rotation. An axial plane contains the axes of rotation of the collector cylinders. A reference plane contains an axis of rotation of this type and has a horizontal surface normal. An intersection angle between the axial plane and the reference plane is, at a maximum, 45 degrees. A first one of the sheet-fed simultaneous printing units has exactly four plate cylinders, of which exactly two are arranged such that they directly interact with the first collector cylinder and has exactly two others which are arranged such that they directly interact with the second collector cylinder. A second sheet-fed printing unit has at least one impression cylinder and at least one plate cylinder, which is arranged such that it directly interacts with the impression cylinder and which is configured a screen printing plate cylinder, or as a flexo plate cylinder or as a numbering plate cylinder. The two collector cylinders of the first printing unit and the impression cylinder of the second printing unit have the same circumference.

An assembly of a first and a second printing or converting apparatus is each at least provided with a number of printing or converting modules disposed one after the other in a main direction, through which in use a substrate web can be guided. The first and the second printing or converting apparatuses are respectively provided with a first and a second rail assembly each extending in a main direction next to or above the associated printing or converting modules and over which at least one processing station is movable. The assembly further includes a transfer assembly which is provided with rail assemblies which are configured to move the at least one processing station from the first rail assembly to the second rail assembly and vice versa and to buffer processing stations.

The present invention is a method for measuring the varnish film thickness of a printed article by obtaining the film thickness of varnish on a sheet (1) on which a pattern is printed on a base thereof with ink and the pattern is coated with the varnish, wherein a metal foil (1c) having a smooth surface is attached to the base of the sheet (1), and the film thickness of the varnish coated directly over the metal foil (1c) is detected with a spectral interference-type film thickness meter (81) so as to determine whether the film thickness of the varnish is acceptable or not on the basis of the results detected by the spectral interference-type film thickness meter (81).

A machine arrangement, for sequentially processing sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. The processing station, including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged. On the circumferential surface of the printing cylinder, four substrates are or can be placed behind each other in the circumferential direction. Each of the substrates that are to be conveyed are retained in one of a force-locking and a form-fitting manner on the circumferential surface of the printing cylinder by at least one retaining element.

A primer roller may include a cylinder having an outer support surface. The outer support surface support surface may have a length in an axial direction and a fixed outer diameter extending along the length. The roller may further comprise, at least at least one elastically deformable annular sleeve having an axial length less than the axial length of the support surface of the cylinder an external diameter greater than the outer diameter of the support surface of the cylinder, and an internal diameter which provides a friction fit on the support surface of the cylinder. The outer surface of the support roller comprises a plurality of fluid outlets. The outlets are distributed about the support surface. Fluid expelled from the fluid outlets enables the sleeve to be slidably positioned relative to the support surface. A priming apparatus and a print press are also disclosed.

A printing machine for printing on a printing substrate web includes a plurality of inline flexographic printing units which are disposed in a plane accessible to an operator of the machine. Each one of the two flexographic printing units of a respective duplex printing station includes a respective impression cylinder and a dryer disposed between the two impression cylinders along a path of web travel of the web of printing substrate. A method of operating the printing machine is also provided.

In some examples, a machine for generating optically variable image elements on a substrate includes a printing substrate infeed and a printing unit including a printing mechanism by which a substrate guided on a transport path is printed with a coating agent containing magnetic or magnetizable particles. A device for aligning the magnetic or magnetizable particles includes a first alignment device in the transport path and a further alignment device arranged upstream therefrom. During normal operation, the further alignment device is fixed to a frame at the transport path. The further alignment device includes a plurality of magnets that are spaced apart from one another transversely to the transport direction and, during operation, remain stationary. The number of magnets included in the further alignment device correspond to a number of columns of image-producing print motifs or groups of image-producing print motifs around a circumference of a forme cylinder.

A system for manufacturing a substrate with a decorative design, such as an image and/or a relief, which has feed means for feeding a foil, digital printing means for printing the decorative design on the foil and coating means for coating the substrate with the foil. The system is configured for printing the foil with the digital printing device after supplying the foil with the feed means and before coating the substrate with the coating means.

A sheet-fed printing unit has a first impression cylinder and a second impression cylinder, which are arranged directly and interactingly in contact and which each have an axis of rotation. An axial plane contains the axes of rotation. A reference plane is a plane which contains an axis of rotation of a cylinder of this type and has a horizontal surface normal. These two cylinders are arranged such that an intersection angle between the axial plane and the reference plane is a maximum of 15°. A transport path is provided for a transportation of sheets, which transport path has a region for the respective impression cylinder in which there is contact between sheets and a casing surface. This region of the transport path for the respective impression cylinder extends over an angular range of at least 270°. A sheet-fed printing machine has a sheet-fed printing unit of this type.

The present disclosure provides a laminating device. The laminating device may include a first conveying device, a second conveying device, and a laminating apparatus. The first conveying device may be configured to convey a film-like structure. The second conveying device may be arranged along a conveying direction of the first conveying device. A conveying speed of the first conveying device may be greater than that of the second conveying device. The second conveying device may receive the film-like structure conveyed by the first conveying device. The film-like structure may form a folded portion on the second conveying device. The laminating apparatus may be configured to convey an object to be laminated and receive the film-like structure conveyed by the second conveying device.
