Abstract:
A method for making a registration of a composite image in a tandem type direct printing apparatus, the tandem type direct printing apparatus comprising a plurality of printing stations for propelling printing particles born on a bearing member through a plurality of apertures formed on a printing head and for depositing the printing particles on a print medium to form an image, the print medium relatively moving in a direction, the plurality of printing stations being positioned in the moving direction of the print medium to form the composite image on the print medium, the method comprising:providing a control electrode for deflecting printing particles adjacent to each aperture of the printing head in at least one of the plurality of printing stations, the control electrode for deflecting printing particles being positioned to one side of the moving direction of the print medium; andapplying a voltage to the control electrode for deflecting printing particles so that the printing particles passing through the aperture of the printing head are deflected to adjust the position of the image formed on the print medium in the perpendicular direction to the moving direction of the print medium.
