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.
A printing press comprising at least one circulatingly movable support element, which includes a circulatingly movable contact surface intended for contact with a printing substrate, and the printing press further comprising at least one first print head configured as an ink jet print head, whose at least one ejection opening is arranged so as to be directed at the at least one support element, and the printing press comprising at least one first charging device, and the at least one first charging device comprising at least one charging electrode, which is arranged so as to be directed at the contact surface, and the at least one first charging device comprising at least one counter-electrode, and the contact surface being at least partially arranged between the at least one charging electrode and the at least one counter-electrode of the at least one first charging device, characterized in that a smallest distance between the at least one charging electrode of the first charging device and the contact surface is greater than a smallest distance between an ejection opening of the at least one first print head and the contact surface, and that the smallest distance between the at least one charging electrode of the first charging device and the contact surface is at least 50 mm.
