摘要

A method for the compensation of a fan - out conditional transverse extension (δ01; δ02) a in a printing press with a plurality of printing inks printed web of printed material (01) with the use of at least one actuating means (07) of an image path controller (03), wherein for the pressure of the plurality of printing inks participating printing mechanism cylinder (02) on the basis of the web of printed material (01) in the transverse to their transport direction (t) which are disposed in a row sections (41; 42; 43; 44; 46; 47) arranged markings (m41; m42; m43; m44; m46; m47) first of all the respective sides register deviation between the respective markings (m41; m42; m43; m44; m46; m47) of in each case, immediately adjacent sections (41; 42; 43; 44; 46; 47) of a with a detecting means (49) is connected to the control unit (33) is determined, whereupon this printing mechanism cylinder (02) in each case by means of a displacement along their respective axis of rotation (38) in a one hand, from the respective ascertained sides register deviations of average value formed reducing manner relative to one another are arranged before the compensation of the lateral expansion caused by fan - out (δ01; δ02) of the web of printed material (01) by means of the at least one actuating means (07) of the image path controller (03) is carried out, wherein all the determined values of the side register deviations due to the displacement of the respective printing-unit cylinder (02) along their respective axis of rotation (38) in order to a maximum a predetermined barriers value corresponding amount can be reduced, when the respective determined value of at least one of the side register deviations is greater than the prescribed limits value.
