Abstract
The invention relates to a method of aligning a plurality of printed motifs on a sheet () in a converting machine (). An actual position (Pa_) at a first sensor is defined as an initial reference position (P_ref) for the sheet, and at least one displacement error (Δd) is calculated and compared to a first threshold (T). If the displacement error is lower than the first threshold, then the angular position (α) of a printing cylinder () in the second flexographic printing unit () is adjusted. However, if the error is higher than the first threshold, then at least part of the of the displacement error (Δd_) is corrected by modifying the speed (V) of a vacuum transfer unit located between the first printing unit and the second printing unit.
