<p>A method of preventing a registration error while printing at least one printing image, wherein, in order to control or adjust the correct length of the printing image, the start and/or the distance of the printing image lines of the printing image are controlled by determining the ratio of the number of rotary encoder signals of a transport web counted during a specific time interval to the number of rotary encoder signals of a cylinder of a printing and by taking into account a change of this ratio as a correction, said ratio being a function of a printing sheet located in a printing nip between the transport web and the printing unit, is characterized in that a changed printing material situation occurring in said printing nip between the transport web and the printing unit is used to achieve registration accuracy immediately.</p> |
