Such inkjet printing devices each have at least one nozzle bar. At least one nozzle bar preferably extends orthogonally to the intended transport path of the printing material over a working width of the printing press. The at least one nozzle bar preferably has at least one row of nozzles. As viewed in a transverse direction, the at least one row of nozzles preferably has the entire working width of the printing machine and / or the width of the bale of the at least one first central cylinder, ie printing cylinder 22 ; 38 For example, at regular intervals nozzle openings. The nozzles are preferably distributed over several print heads. A surface of the respective print head surrounding the nozzle openings is preferably called nozzle area.

Each nozzle bar preferably has at least one supporting body. On the support body directly or preferably indirectly, for example via positioning means and / or in particular designed as alignment means connecting elements, the printheads this nozzle beam attached.

A travel of the adjusting device comprises in a first embodiment exclusively in a setting direction, which has at least one component in a radial direction to the axis of rotation of the central cylinder and which is further preferably oriented exclusively radially to the axis of rotation of the central cylinder. In a second embodiment, the adjusting travel of the adjusting device comprises at least 75%, more preferably at least 90% of its entire length in a setting direction which has at least one component in a direction parallel to the axis of rotation of the central cylinder and which more preferably exclusively parallel to the Rotary axis of the central cylinder is oriented. A small part of the travel then preferably has in a radial direction, in order to avoid damage to the print heads.

The adjusting movement by means of the adjusting device serves, for example, to make printheads accessible for maintenance and / or cleaning work and / or a single or group-wise replacement of one or more print heads. In particular, a temporary access for a cleaning device to respective printheads can be created by the adjusting movement by means of the adjusting device.

Preferably, a plurality of print heads are arranged side by side on the at least one nozzle bar in the transverse direction, the nozzle faces, for example, have the shape of a rectangle, but more preferably the shape of a trapezoid and / or a parallelogram. Since such individual printheads are usually not provided with nozzles up to an edge of their housing, printheads need to be overlapped with respect to the transverse direction. The at least one row of nozzles is preferably not formed as a single linear juxtaposition of nozzles, but instead results as a sum of several individual, more preferably two, arranged in the circumferential direction offset from each other juxtaposition of nozzles. For this purpose, different embodiments are possible.

For example, in a first embodiment, at least two, and more preferably exactly two, transversely extending rows of printheads are staggered in the circumferential direction of the first central cylinder, preferably such that transversely successive printheads preferably alternately belong to one of the at least two rows of printheads; always prefers alternately a first and a second of two rows of printheads.

For example, a respective nozzle surface of each print head and / or at least one respective surface of the print head delimiting the print head in its ejection direction has a shape deviating from a rectangular shape, in particular the shape of a preferably symmetrical trapezoid and / or a parallelogram. As a result, the nozzle surfaces of adjacent print heads may overlap in the transverse direction and the print heads may nevertheless be arranged directly adjacent to one another in the transverse direction, in particular without being offset relative to one another in a transport direction T. Such a series of printheads is called, for example, obliquely overlapping series of printheads.

Each double row of printheads or obliquely overlapping row of printheads is preferably associated with and / or assignable to a coating agent, in particular a printing ink of a specific color, for example one of the colors black, cyan, yellow and magenta or a varnish, for example a clearcoat. For example, one coating agent is assigned two double rows of print heads or two obliquely overlapping rows of print heads. The at least one print head operates to produce coating agent drops, preferably by the drop-on-demand method, in which coating agent drops are selectively produced as needed.

In a regular printing operation, all print heads are stationary. This ensures a permanent passport-oriented and / or register-oriented alignment of all nozzles. There are different situations in which, apart from the movement by means of the adjusting device, a defined alignment movement of the print heads is necessary. The respective alignment movement of the print heads preferably takes place by means of at least one positioning device.

Preferably, at least one positioning device is arranged, by means of which at least one print head can be adjusted in its position, in particular in its position relative to other print heads of the printing unit and / or to other print heads belonging to the same nozzle bar and / or in its position with respect to the transverse direction and / or in its position with respect to a pivot axis oriented parallel to its nozzle ejection direction. Preferably, a plurality of positioning devices are arranged. For example, each print head is assigned its own positioning device. Preferably, however, at least one such positioning device is assigned to several printheads together, in particular such that a plurality of printheads can be adjusted in position by means of their associated common positioning in particular, in their position relative to the common nozzle beam and / or relative to other printheads on these common nozzle bars are arranged and / or in their position with respect to the transverse direction and / or in their position with respect to a pivot axis which is oriented parallel to the direction of their Düsenausstoßrichtung.

By means of the alignment of the respective printhead is preferably individually aligned to the body, in particular manually and / or in its position with respect to the transverse direction and / or in its position relative to a pivot axis which is oriented parallel to its Düsenausstoßrichtung. In this way can preferably several, in particular at least three and more preferably at least four printheads are aligned relative to the base body and thus also to each other.

Preferably, these several, in particular at least three and more preferably at least four printheads and the main body are each part of a first assembly. The printheads of the first assembly, for example, outside of the printing unit relative to the body and thus aligned with each other. As a result, they can be aligned with a corresponding tool and / or with the aid of a camera detecting the relative position and / or with particularly good accessibility to the base body and thus also to one another. As a result, a particular precisely aligned respective first assembly is generated.

Preferably, the respective nozzle bar is arranged supporting several such first assemblies. Preferably, these several first assemblies are adjustable in their respective position relative to the support body of this nozzle beam via their own positioning. Accordingly, a plurality of positioning devices are preferably arranged on a support body. Preferably, at least indirectly via the positioning a plurality of first modules are arranged on a support body, in particular by means of the plurality of positioning each in their position relative to the support body adjustable. For example, the print heads of two obliquely overlapping rows of print heads are arranged on a carrier body at least indirectly via the positioning devices.

By moving the support body all the print heads attached directly or indirectly can then be moved, in particular without being changed relative to one another without their relative orientation.

In order to determine which printhead or which group of printheads has to be moved to which extent and in which direction in order to produce an optimum print result, it is preferred to print and examine at least one test print image.

Such relative settings are, for example, relative geometric positioning of the printheads or groups of printheads and / or relative actuation times, in particular drop ejection times of the printheads and / or groups of printheads. The relative settings additionally or alternatively include, for example, relative settings which relate to at least one color density and / or at least one area coverage and / or at least one point size of generated pixels. In the following, the relative setting is related to geometric positioning and / or activation times, in particular drop ejection times. However, the devices and / or processes described also relate to the other relative settings mentioned, as far as no contradictions arise from this.

The at least one adjustment sensor and in particular the at least two adjustment sensors are preferably designed at least as position sensors. The at least two adjustment sensors, in particular position sensors, are designed, for example, as cameras and / or as CCD sensors and / or as CMOS sensors.
