Abstract
A method and a control device for prevention of registration errors. In the current state of the art, a control circuit of a control device eliminates registration errors. A first sensor detects a sheet before a printing module and a second sensor detects the sheet after the printing module, an actual number of pulses is counted between the detection of the sheet by the first sensor and by the second sensor and this actual number of pulses is fed into a closed-loop control system as an actual parameter, the actual number of pulses is compared with a reference number of pulses, which represents a reference parameter of the closed-loop control system, a control signal of the closed-loop control system is determined from this comparison, and a number of pulses is conducted into a controlled process of the closed-loop control system, which number of pulses is in direct relation to the current sheet to be printed in the printing module.
