An anilox printing unit includes, as inking unit rolls, an ink applicator roll and an engraved roll mounted in rapid change roll sockets, for removing the engraved roll from the roll sockets and inserting another engraved roll into the roll sockets by an operator. The engraved roll is hollow and a temperature control fluid flows therethrough. The engraved roll and the ink applicator roll each have bearer rings. A device which presses the bearer rings of one inking unit roll against the bearer rings of the other inking unit roll has springs for compensating for diameter differences as a result of manufacturing tolerances between the bearer rings of the engraved roll and the bearer rings of the other engraved roll and for compensating for thermally induced diameter changes of the bearer rings of the engraved roll. A printing press having an anilox printing unit is also provided.

A method of operating an anilox printing unit in which ink accumulates on and detaches from a feed blade and, after detaching from the feed blade, forms ink accumulations on a screen roller, and in which a gap is formed between the screen roller and a further roller for the ink accumulations to pass through the gap without contacting the further roller, includes forming the gap by displacing the axis of the further roller and evening out the ink accumulations on the screen roller to such an extent that the ink accumulations that have been evened out pass the gap without contacting the further roller. A smoothing roller, for example, may be used to even out the ink accumulations. A printing press for carrying out the method is also provided.

A printing press includes a first rotary body with a first bearer ring and a second rotary body with an axle which eccentrically supports a second bearer ring. The second bearer ring is in rolling contact with the first bearer ring and is rotatably coupled to the second rotary body.
