    摘要: A printing machine includes a plurality of inkjet print heads arranged together in a printing unit and controlled by a control unit. At least two of the inkjet print heads are jointly arranged in relation to a stationary position in a transport path at a printing nip. The control unit activates a first inkjet print head when a substrate of a first substrate type moves past the stationary position, and activates a second inkjet print head when a substrate of a second substrate type moves past the stationary position. The first substrate type and the second substrate type differ from each other in material and/or nature of a surface to be printed. The inkjet print heads arranged in the printing unit are each configured to print an ink that comprises at least one colorant, both for the first substrate type and for the second substrate type.

    摘要: A sheet-fed printing press has at least one coating assembly configured as a non-impact coating assembly. The sheet-fed printing press has at least one transport belt which extends, having at least one transport section of a circular path thereto, parallel to a transport direction along a partial region of a transport path provided for a sheet. At least one coating location of the at least one coating assembly is arranged along the transport section of the at least one transport belt. At least one printing head is arranged connected to at least one first frame of the at least one coating assembly. The at least one transport belt is arranged, connected to at least one second frame, via at least one deflection device and at least one radial bearing. The at least one first frame, apart from at least one installation surface which is different from the at least one first frame and the at least one second frame, is arranged in contact to the second frame at most via flexible connections.

    摘要: A printing press has at least two units in the form of modules, at least one of which is in the form of a non-impact coating module and has at least one print head. The at least two modules each have at least one dedicated drive which is used to effect transport of a substrate through the module or through an effective region of the module. Along an intended transport path, there is at least one first application point, provided for the application of a color coating agent, an effective region of at least one drying device assigned to the first application point and at least one further application point provided for color coating agent application, and further oriented towards the same side, of at least one non-impact coating module, and an effective region of at least one further drying device assigned to the further application point. At least one print head is preferably one of connected and connectable to at least one positioning device. The at least one positioning device preferably has at least one positioning drive.

    摘要: A printing assembly has a frame having two side walls, between which, a transport path for the transport of printing material, extends. A transport direction is defined by the transport path. The printing assembly has at least three cross bars which extend in a transverse direction between the side walls. They are arranged one behind the other with respect to the transport direction. The printing assembly has at least three printing heads which are arranged one behind the other. At least one first additional device, is arranged on each of the cross bars. At least one second additional device, is arranged on each of the crossbars.

    摘要: A printing assembly has a frame having two side walls and has at least one cross member which extends at least in a transverse direction between the side walls and which has at least one supporting body which can be moved in relation to the frame in at least one parking direction and which extends at least in the transverse direction. At least one printing head is arranged on the supporting body and can be moved jointly with the supporting body. At least one first contact point, which is arranged on the supporting body, and at least one second contact point, which is arranged on the cross member, form a first contact-point pair. The first contact points lie opposite each other in the parking direction and are one of in contact and can be brought into contact with each other. At least one third contact point, which is arranged on the supporting body, and at least one fourth contact point, which is arranged on the cross member, form a second contact-point pair. The second contact points lie opposite each other at least at times at least also in a supporting direction orthogonal to the parking direction and orthogonal to the transverse direction and are one of in contact and can be brought into contact with each other.
