At least one printing fluid of a printing fluid supply system of a printing press is changed. A printing unit of the printing press includes a print head. At least a first printing fluid or second printing fluid is selectively conducted from at least one supply unit to the print head. The at least one supply unit includes a reservoir of the first printing fluid and a reservoir of the second printing fluid. The at least one supply unit further includes an intermediate tank of the first printing fluid and an intermediate tank of the second printing fluid arranged between the reservoirs and the print head in the flow direction of printing fluid. The first and second printing fluids are conducted from their respective intermediate tanks to the print head, and there is no return of the printing fluids from the intermediate tanks to the respective reservoirs.

Method for changing at least one printing fluid, and method for cleaning and/or maintaining at least one printing fluid supply system, and printing press

A printing assembly has at least one transport direction defined by a transport path provided for the transport of printing material through the printing assembly. The printing assembly has at least one first support body on which at least one first image-generating device is arranged and which at least one first support body extends both in the transport direction and in a transverse direction that is oriented horizontally and orthogonally to the transport direction. The printing assembly has at least one first temperature-control device for the targeted generation of a temperature difference between a first point of the at least one first support body and at least one second point of the at least one first support body. That second point is spaced apart from the first point, at least in the transport direction.
