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.

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.

A hybrid transfer machine includes: a body including a first drum installation part, a second drum installation part, a first body, a second body, and a worktable; a first drive means configured to allow wound fabric to be unwound; a thermal transfer unit configured to be installed in the second body, and to press and heat the fabric and transfer paper; a piece-type roller arm configured to be installed in the second body, and to guide the transfer paper to the third drum installation part; a second drive means configured to allow the transfer paper to be wound; a third drive means configured to allow the fabric to be wound; and a conveyer configured to be installed in the body, and to transfer the fabric and the transfer paper to the third and fourth drum installation parts.

A turret styled container decorator machine is disclosed having a rotatable turret and a number of circumferentially spaced container holding assemblies for holding a variety of pieces of media, such as a drink container, the surface of which is to be printed upon with an image. A plurality of workstations are positioned around the perimeter of the turret through which each media holder passes as the turret rotates. Each workstation includes an ink printing assembly and a curing assembly so that ink may be applied and cured as each piece of media is indexed into each workstation location. Each printing workstation may be removed and replaced with a different arrangement or configuration of ink heads to suit different types of media sizes and shapes, and the turret holds a plurality of media holding means assigned to a pie-shaped section of the turret adjustable to accommodate various types of media geometries.

The present invention relates to an inversion transfer module (60) for a converting machine having a printing module (16) comprising a first printing unit (17) arranged to print on a top side (S1) of the sheet (1), and a second printing unit (17) arranged to print a bottom side (S2) of the sheet. The inversion transfer module is arranged between the first printing unit and the second printing unit and comprises a first inversion vacuum transfer (62) arranged to contact the first side of the sheet and a second inversion vacuum transfer (64) configured to contact the second side of the sheet, whereby the inversion transfer module is configured to change the side of adherence and transportation of the sheet.

The invention relates to a mobile window apparatus and a hot foil stamping device including the apparatus. The mobile window apparatus comprises at least one first window portion, the first window portion movable in a first direction; at least one second window portion movable in a second direction different from the first direction; and an actuating means configured to move the first window and the second window, respectively; wherein said actuating means moves said first window portion and said second window portion between a closed position and an open position, in said open position, said first window portion and said second window portion being spaced apart from each other to form an access opening, and in said closed position, the first window portion and the second window portion are close to each other so as to substantially shield the access opening and to keep a gap between the first window portion and the second window portion for passing through a sheet material for processed.

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 print quality examination device is provided in a printing machine (1) provided with a printing unit (3) that performs printing on a mirror-reflection member (5a) of a sheet (5) to which the mirror-reflection member (5a) is added. The print quality examination device of the printing machine is provided with an examination camera (18a) that images a picture printed on the sheet (5), a light source (18h) that irradiates the sheet (5) with light, and a print quality examination unit (18g) that examines the quality of the picture printed by the printing unit (3) based on image data imaged by the examination camera (18a). The examination camera (18a) or the light source (18h) is configured to be movably supported on an arc about a detection point (P) imaged by the examination camera (18a) for the sheet (5).
