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.

In some examples, a printing press includes a support element with a circulatingly movable contact surface for contacting a printing substrate. An ink jet print head includes an ejection opening arranged to be directed at the support element. Additionally, the printing press includes a charging device that includes a charging electrode, which is arranged to be directed at the contact surface. The charging device further includes a counter-electrode, and the movable contact surface is at least partially arranged between the charging electrode and the counter-electrode of the charging device. A smallest distance between the charging electrode and the movable contact surface is greater than a smallest distance between the ejection opening of the ink jet print head and the contact surface. For example, the smallest distance between the charging electrode and the contact surface may be at least 50 mm.
