摘要： An offset printing unit includes at least one cylinder pair with a form cylinder and a transfer cylinder. The transfer cylinder cooperates with an impression cylinder in such a way that ink can be applied to a printing material web guided between the transfer cylinder and the impression cylinder. In order to permit the economic production of multifarious products with a relatively low technical outlay, the form cylinder is fitted in the circumferential direction with one, and in the longitudinal direction with at least four, portrait printed pages in broadsheet format. The form cylinder may optionally be fitted with landscape printed pages in tabloid format or portrait or landscape printed pages in book format. A circumference of the form cylinder receives one flexible printing plate and a longitudinal length of the form cylinder receives at least one flexible printing plate. The circumference of the transfer cylinder and the circumference of the impression cylinder in each case is an integral multiple of the circumference of the form cylinder.
