摘要

The invention relates to a method for avoiding printing errors in conjunction with the stopping of a printing unit of a tube or can printing machine, having an impression cylinder with at least one printing segment which can be pivoted in, having at least one inking unit, and having mandrels of a transporting system for the tubes or cans, separately actuable servomotors being used to drive them in each case. According to the invention, when stopping the impression cylinder, the braking operation is only introduced when a current printing operation has been completed without changing the circumferential speed and when all the printing segments have been completely inked again and then pivoted in.
