Abstract: A print assembly including an upstream print unit and a downstream print unit adapted to print, one after the other, a strip to be printed over a print width. Each upstream and downstream print unit defining a print interstice and the two print interstices defining an interstice plane. The two upstream and downstream print units defining a middle line. The print assembly includes a compensator having at least one compensation path between the upstream and downstream print units for a partial strip of the strip to be printed. Each compensation path is longer than a neutral path for a neutral portion of the strip to be printed.

Abstract: A method for regulating a first printing unit is provided. The first printing unit includes a plate cylinder, a first blanket cylinder carrying a tubular blanket and an impression cylinder. The first blanket cylinder defines a region of contact with the plate cylinder. The impression cylinder defines a region of counter-pressure with the first blanket cylinder.

Abstract: An infeed device for drawing a material web into a web-fed rotary printing machine in an infeed direction includes an infeed channel, an infeed element guidable in the infeed channel, and an infeed triangle releasably connectable to the infeed element, the infeed triangle having fastened thereto a leading end of the material web to be drawn into the rotary printing machine, and the infeed triangle having, on a side thereof facing towards the infeed channel, a deformation extending at least approximately perpendicularly to the infeed direction.

Abstract: A method for regulating the ink-to-wetting agent equilibrium in a rotary offset printing machine, the wetting agent quantity being determined especially using the signals of a sensor which measures the light reflectance of an area on the printing form of the rotary printing machine that is wetted by a wetting agent.
