Abstract: An apparatus, a printing press and method for correcting the printing position of a printing unit of a printing press that has at least one sensor unit, where the method includes the steps of detecting an actual position of at least one print mark via the sensor unit, where the print mark is printed onto a printing material via the printing unit, determining of a deviation of the detected actual position from a setpoint position, determining at least one difference value that characterizes the deviation, determining a buffer value from a number of basic values previously stored in a memory, determining a correction value by subtracting the buffer value from the difference value, storing the determined correction value in the memory as one of the basic values, and correcting the printing position based on the determined correction value.
