A printing unit of a web-fed rotary press has a plurality of press units, each press unit having a form cylinder, a transfer cylinder, an inking unit and optionally a damping unit, and having at least one impression cylinder. Each form cylinder rolls on the respective transfer cylinder and each transfer cylinder rolling on an impression cylinder in a thrown-on position of the printing unit, in order to apply single-color printed images onto a printing material which is moved through between the transfer cylinders and the or each impression cylinder. Each form cylinder bears a plurality of printing images next to one another in the axial direction, by which corresponding single-color printed images are applied to the printing material. The printing images which are arranged next to one another in the axial direction of the respective form cylinder are offset with respect to one another in the circumferential direction in such a way that deviations in the circumferential register between the single-color printed images which are to be printed in different press units can be compensated for.

Printing unit of a web-fed rotary press

A cylinder for an offset printing press comprising a steel core and a heat-conducting layer arranged on the steel core in order to uniformly distribute localized steel core heating. The heat can consist of copper and can be arranged in or underneath a functional layer on the cylinder.

Rolls and cylinders with a steel core for offset presses

A rubber cylinder sleeve for an offset printing press includes an inner carrier sleeve that has a circumferential and an axial direction. The carrier is expandable outwardly by an application of compressed air from the interior. The rubber cylinder sleeve also includes a single rubber layer having an inner surface disposed on the inner carrier sleeve and an outer surface for contacting the printing plate. The single rubber layer includes a plurality of compressible elements for increasing the compressibility of the single rubber layer and a plurality of filaments for increasing the stiffness of the single rubber layer. The compressible elements and the filaments are disposed at a distance from the outer surface.
