Abstract: The invention relates to a sheet-fed press (10) comprising a sheet feeding device (11) for introducing sheets that are to be printed into the sheet-fed press, at least one printing unit (12) and/or coating unit (13) for printing the sheets with a static printed image that is identical for all sheets, a discharging mechanism (14) for discharging printed sheets from the sheet-fed press, and at least one printing device (1) which includes no printing form and is integrated into the sheet-fed press (10) to print the sheets with an especially dynamic, variable printed image. According to the invention, the printing device (1) is integrated in the region of a supply strip (19) in the sheet-fed press (10) which guides a stream of products to the first of the printing units (12).

Abstract: A method is described for producing an RFID label using a printing process. The required parts are applied to the label in a simple way and preferably also to protect the antenna against mechanical or chemical damage. At least parts of the antenna and the tuned circuit which are required for functioning of the RFID label are applied to the printing material by sheet-fed offset printing or, directly or indirectly, by way of a relief printing plate.

Abstract: An undershot inking unit and associated method are disclosed. The undershot inking unit includes an ink fountain roller that is controlled independently of the printing speed of the printing machine, and in which the rotational contact angle of the distributor roller on the ink fountain roller is varied according to the printing unit speed. The method comprises controlling the rotational speed of the ink fountain roller independently of the printing speed of the printing machine; and varying the rotational contact angle of the intermittent ductor roller on the ink fountain roller according to the printing speed of the printing machine. In a preferred embodiment, the apparatus includes two coaxial cams rotatably adjustable with respect to each other. Each cam includes a predominant circumferential contour and a subordinate circumferential contour.
