Abstract

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.
