A forme cylinder is supported and adjusted in a printing group of a rotary
printing press, which group includes a transfer cylinder and a
counter-pressure cylinder, which two cylinders include interacting
support elements. The forme cylinder does not include a support element
which interacts with the transfer cylinder. The forme cylinder has a
shaft distance that can be adjusted during printing to adjust a contact
pressure between the forme cylinder and the transfer cylinder. The forme
cylinder may be covered with a waterless printing forme. The contact
pressure between the forme cylinder and the transfer cylinder can be
adjusted to a property, such as the compressibility, of the waterless
printing forme.
