Temperature-dependent print image position error compensating method for rotary printing machine, involves correcting print job specific register adjusting data by pre-determined printing unit-specific side register correction data

摘要

The method involves continuously determining temperature distribution in cylinder-axial direction. Print job specific register adjusting data are corrected by pre-determined printing unit-specific side register correction data during a printing operation in printing units of a rotary printing machine. Temperature gradients are reduced by separate temperature devices for each of the printing units of the machine, where the machine comprises register adjusting devices for position correction of applied print images. An independent claim is also included for a device for compensating a temperature-dependent print image position error in a rotary printing machine.
