Abstract
A method of adjusting a roller (18) in a rotary printing press (10), includes the steps of a) mounting the roller (18) in a preparation rack (24) so as to be rotatably supported therein, b) scanning the peripheral surface of the roller, thereby to detect a topography of the roller surface, c) deriving set data for the adjustment of the roller from the topography, and storing the set data, d) mounting the roller in the printing press (10), and e) adjusting the roller in accordance with the set data.

A method of adjusting a roller in a rotary printing press, comprising the steps of:
- a) mounting the roller in a preparation rack so as to be rotatably supported therein,
- b) scanning a peripheral surface of the roller, thereby to detect a topography of the roller surface by using a follower roll to detect the topography of the roller,
- c) deriving set data for the adjustment of the roller from the topography, and storing the set data,
- d) mounting the roller in the printing press, and
- e) adjusting the roller in accordance with the set data.

A rack for one of mounting printing plates on a printing cylinder and for creating a printing pattern on the surface of the printing cylinder, the rack being adapted to rotatably support the printing cylinder and comprising:
- a detector for detecting a reference mark on the printing cylinder, and
- a scanning system for mechanically scanning the surface of the printing cylinder for detecting the surface topography of the printing cylinder.
A scanning system for measuring a surface profile of a rotating cylinder, comprising a follower roll that is movably supported to roll over the cylinder, and a contactless distance sensor fixedly mounted at a distance from the periphery of the follower roll in a position opposite to the cylinder for measuring the position of a peripheral surface of the follower roll.
