A method of printing comprising includes spreading and flattening a plastic film web before passing the plastic film web through a first printing unit; and spreading and flattening the plastic film web after the plastic film web exits the first printing unit and before passing the plastic film web through a second printing unit.

A calibration plate is arranged on a support surface of a table. The calibration plate has first and second alignment marks arranged in one direction, and third and fourth alignment marks arranged in another direction that is orthogonal to the one direction. The first and second alignment marks that move in a front-and-rear direction are imaged by a first camera. The one direction of the calibration plate is made parallel to a front-and-rear direction based on the image. The positions of second and third cameras are adjusted based on the third and fourth alignment marks. The second and third cameras, positions of which have been adjusted, are moved to positions below the transfer roller, and a reference line formed at the transfer roller is imaged by the second and third cameras. An orientation of a rotation shaft of the transfer roller is adjusted in a plane parallel to the support surface based on these images.

An assembly for a printing machine includes: a printing plate cylinder, which has a cylinder body; a printing sleeve, which is arranged on an outer surface of the cylinder body; and a transmission device, which has a connecting point on the printing plate cylinder side and a connecting point on the printing sleeve side, which connecting points can be connected by means of a connecting element to form a transmission connection. The connecting element is displaceable between a retracted position, in which the transmission connection is interrupted, and an extended position, in which the transmission connection is formed for at least one of the following types of transmission: transmission of a fluid, transmission of signals and transmission of electrical energy. Furthermore, a method is provided for producing an arrangement for a printing machine.

A structural underblanket unit (10) for blanket cylinders (100) of printing machines, comprising a first layer (11) made of rubber, a second layer (12) made of polyester and a third layer (13) made of fabric. The layers (11, 12, 13) are solidly bonded to one another so as to define a multilayer structural unit (10) having an overall transversal thickness (S) corresponding to the sum of the transversal thicknesses (S11, S12, S13) of said layers, the order of bonding of said layers being any whatsoever. A process for adjusting a distance of a printing blanket (101) from a wall (102) of a blanket cylinder of a printing machine.
