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

The invention relates to 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 the printing material web (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 rapportistlänge l_i and storage of the repeating lengths - web voltage - values (l_i; F_i)d) change in rotation, 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).
