Abstract
To match the width of zone adjustment of doctor blade elements or zones of a continuous doctor blade of a printing machine inking system to pick up units of photoelectric transducers scanning patterns, in columnar zones, so that the degree of inking of the ductor roller can be matched to the degree of printing density of the pattern in the respective zones by control of the doctor blade elements or zones, the transducer arrangement includes a plurality of transducer elements of selectively different transducing widths, associated with the zones of information coverage of selectively different widths to match the width of the transducing means to the zones and for transmission of thus matched transduced signals to the printing apparatus and derive an output of utilization signals with respect to the zones of selectively different widths. Transducing elements of respectively different widths may be used (FIG. 3); or much narrower transducing elements, the outputs of which are then combined in a summing circuit and in which the number of the transducing elements, transverse to the transport direction of the pattern, is equal to the common divisor of the zone width (e.g. for zone widths of 30, 35, 40 mm, a transducer width of 5 mm); or transducers of fixed widths can be located on parallel arms of a scissor grid, the relative inclination of which with respect to the transducing direction can be changed, to provide for infinitely variable overlap, and coverage of the width of the pattern, in zones of infinitely variable dimension.
