Abstract

A method for preventing limit values from being exceeded in sheet-fed printing machines includes acquiring values relevant to the printing process with respect to individual sheets, and processing those values so that predetermined limit values are maintained, detecting the development trend of a relevant value in the course of a series of sheets, and initiating measures when a change in the values occurs that would lead to a limit value being exceeded in an additional predetermined number of sheets if a continuation of the trend occurs; and a device for performing the method.
