Examples include a printing unit having a first tool-dependent printing nip formed by a pair of cooperating rotational bodies. The printing unit includes, along a transport path, downstream from the first tool-dependent printing nip, a first alignment cylinder and a first non-impact printing position to which at least one first print head is assigned. The printing unit further includes, along the transport path, downstream from the first non-impact printing position, a first curing device having a first curing area assigned thereto. The printing unit, downstream from the at least one first alignment cylinder, including at least one second alignment cylinder and a second non-impact printing position, to which a second print head is assigned. The printing unit, downstream from the second non-impact printing position, comprising a second curing device having a second curing area assigned thereto.

Examples include a printing unit, which has at least one first tool-dependent printing nip formed by a pair of cooperating rotational bodies. The printing unit includes, downstream from the first tool-dependent printing nip, along a transport path provided for a transport of substrate, at least one first alignment cylinder and at least one first non-impact printing position, to which at least one first print head is assigned. The printing unit further includes, downstream from the first non-impact printing position, along the transport path provided for the transport of substrate, at least one first curing device having a first curing area assigned thereto. Additionally, in the region of the first non-impact printing position, the transport path provided for the transport of substrate is defined by the first alignment cylinder or a rotational transport body arranged directly upstream from the first alignment cylinder.

Examples include a cylinder for aligning magnetic or magnetizable particles contained in a coating agent on a substrate. In the region of the outer circumference of the cylinder, in a matrix-like manner, a number of magnetic elements that provide magnetic fields are arranged in n rows extending in an axially parallel manner and in m columns extending in the circumferential direction. Additionally, suction elements with suction openings pointing outwards are also arranged in the circumferential region. A plurality or all of the magnetic elements are arranged one behind the other and are each combined with at least one assigned suction element in respective modular units as action units in a plurality or all of the columns of magnetic elements. The action units can be positioned in each case independently of the other action units in the circumferential direction and/or can be detached from the cylinder.
