disengagement movement is respectively added or subtracted or is added on the one side and is subtracted on the other side depending on the conveying direction of the web 08 and whether the forme cylinders 02 11 are disengaged in the same or in the opposite direction with respect to each other in connection with the linear embodiment of the double printing group 13 for example as seen in fig7 in particular the amount of the relative speed such as angular position or angular speed resulting from the disengagement in the case of the transfer cylinder 07 whose movement during disengagement has a component in the conveying direction of the web 08 is subtracted while in the case of the transfer cylinder 03 whose movement during disengagement has a component which is anti parallel to or opposite to the conveying direction of the web 08 it is added for placing the double printing group 13 against a web 08 running at production speed for example following a flying plate change or at start up the conditions must be applied in accordance with the relative speed resulting from the engagement the amount of the relative speed such as angular position or angular speed resulting from the engagement in the case of the transfer cylinder 07 whose movement during disengagement has a.
