Claim:
A method of minimizing the influence of register differences in multicolor printing, in a digital printing press, having a plurality of printing units ( 5 , 5 ′, 5 ″, 5 ′″) including a plurality of writing heads respectively, said method comprising the steps of: measuring the value of register values ( 1 ) at a number of locations transversely with respect to a transport direction through a printing press, setting register values ( 1 ) in the transport direction ( 2 ) which are different transversely with respect to such direction to a value between the extremes ( 3 , 3 ′), wherein a number of individual values of the register ( 1 ) are measured and an average value ( 4 , 4 ′) is determined from the variation in such register values, and brought into alignment with the average value ( 4 , 4 ′) from at least one further color printing unit ( 5 , 5 ′, 5 ″, 5 ′″).
