A depiction of a printed image, which is printed onto a printing material by the printing press, together with a plurality of ink zones, arranged next to one another transversely, with respect to a transport direction of the printing material which is guiding through the printing press, of at least one inking unit, which is arranged in the printing press, are indicated on a display surface of the display device of a control unit in a controlled manner. The inking zones are indicated by way of parallel boundary lines, which delimit them in each case. For the display of the boundary lines which delimit the inking zones, the control unit fixes one of the color thereof and the brightness thereof and the opaqueness thereof in a manner which is dependent on a minimum contrast which has previously been set in the control unit, in order to form an image region, adjoining the boundary lines, of the printed image which is displayed on the image surface of the display device and displays the boundary lines which delimit the inking zones in the contrast ratio which is fixed in respect of the printed image which is displayed on the display surface of the display device.
A screen-printing unit in a printing machine comprises a screen cylinder which carries a screen-printing stencil and in which a squeegee is moved, from the inside, into contact with, and away from the screen-printing stencil. The screen cylinder is moved into contact with an impression cylinder, such that a printing position is formed, and is moved away therefrom, such that a gap is formed. The screen cylinder is moved away from the impression cylinder, in a first phase, when the squeegee is in a non-contacting position. In a second phase, at least one sheet of printing material is passed through the printing position when the squeegee continues to be in a non-contacting position and the screen cylinder is at least temporarily in a contacting position. For subsequent sheets of printing material, in a third phase, the screen-printing unit is operated with the squeegee one of permanently and cyclically, such as at least once for each sheet of printing material, in a contacting position.

A machine arrangement sequentially processes sheet-like substrates with multiple different processing stations each having a substrate-guiding unit and a substrate-processing unit. At least one of the processing stations has, as a substrate-processing unit, at least one non-impact printing device which prints on the substrate. The processing station with the at least one non-impact printing device has a printing cylinder. Each non-impact printing device is arranged at the circumference of the printing cylinder. The printing cylinder is triple-sized or quadruple-sized. A double-sized or a triple-sized transfer drum, or a corresponding feed cylinder, is arranged directly upstream of this printing cylinder. Alternatively, a double-sized or a triple-sized transfer drum, or a corresponding transfer cylinder, is arranged directly downstream of this printing cylinder.
