Rotary printing machine for packaging industry, has color decks, in which one deck comprises control unit that is designed, such that adjusting system is controlled based on data for optimally adjusting position of cylinder for printing

摘要

The machine has color decks (A-J), each comprising a printing cylinder and an adjusting system for adjusting position of the cylinder based on another component of the machine. One deck has a control unit (50) for capturing and processing data relating to the cylinder, where the data describes the topography of the surface of the cylinder and/or a spatial relationship between a printing pattern and a reference mark (36) on the cylinder. The control unit is designed, such that the system is controlled based on the data for optimally adjusting the position of the cylinder for printing. An independent claim is also included for a method for adjusting a cylinder in a rotary printing machine.
