Abstract
There is disclosed a simple and compact additional printing apparatus for a rotary press and a printing unit. The additional printing apparatus includes an ink jet printing device comprising an ink jetting nozzle section and unnecessary ink droplet deflection unit. The ink jetting nozzle section includes a plurality of orifices arranged in a row and ink droplet formation unit. The unnecessary ink droplet deflection unit corresponds to each of the orifices. The ink jet printing device is disposed at a predetermined position in proximity to a paper web pass at which position an additional image can be printed on paper web in alignment with an image printed by the printing cylinder. The apparatus further includes signal output units for outputting a first signal related to the rotational phase of the printing cylinder or the position of a printed image printed through rotation of the printing cylinder, a second signal related to the running speed of paper web, and a third signal related to the amount of travel of the paper web, and control unit for controlling the unnecessary ink droplet deflection unit of the ink jet printing device. The control unit processes image data from a data source and the first through third signals so as to print an image as profiled by the image data at a position specified by the image data in alignment with an image printed by the printing cylinder.
