A method for determining a repeating lengths - web voltage - function on a printing press and regulation of the auxiliary device for carrying out

摘要

A method for operating a printing machine (100), in which a repeating lengths - web voltage - function is determined, and which contains at least the following steps:a) continuous printing a print motif (2) with at least one plate cylinder (12) to a web of material (1; 1'');b) subjecting the web of printed material (1; 1 '') with a first web tension (f1)c) measuring the web tension (f_i), Measuring the repeat - actual length (l_i)and storage of the repeat - - - istlängen web voltage values (l_i; F_i)d) a simple or multiple change in the web tension (f_i) the web of printed material (1; 1 '') and at least single repetition of step c);e) calculation of the repeating lengths - web voltage - function of the repeating lengths - web voltage - pairs of values (l_i; F_i).
