Abstract: A press unit of a web-fed press is disclosed. The press unit has at least one pair of cylinders including a form cylinder and a transfer cylinder and also an impression cylinder, it being possible for a printing material web to be led through between the transfer cylinder and the impression cylinder and covered with ink. The pair of cylinders has a width of eight horizontal or upright newspaper pages, and the width of the form cylinder has a ratio of 1:3 to 1:5 to the circumference of the form cylinder.

Abstract: A printing press simulator is integrated into a control desk of a printing press, it being possible for input data to be predefined by an operator on an input device of the control desk during the simulation. A simulation unit of the printing press simulator simulates the printing process and the behavior of the printing press on the basis of the input data and produces output data which can be displayed on an output device of the control desk. The printing press simulator has a database with intended image data based on the prepress stage for a specific number of customer-specific and updatable printed pages, and the printing press simulator also has a manipulation unit which, on the basis of the input data predefined by the printer, changes the intended image data based on the prepress stage and stored in the database in order to provide simulation image data.

Abstract: A cutting cylinder is mounted such that it can rotate and be driven and is provided with four cutting blades on its circumference, which blades divide the circumferential length into four sections arranged on the circumference of the cutting cylinder.
