  • Method and device for changing the trajectory of ink droplets
    Patent number: 7393086
    Abstract: The invention relates to a method for changing the trajectory of ink droplets generated by and emitted from a print head which operates in a continuous manner, the ink droplets being electrostatically charged and deflected in a plane out of an original trajectory by at least one electrical field in a first deflecting device, the ink droplets being deflected in the same plane by at least one electrical field in a second deflecting device. The invention further relates to an inkjet printing device for emitting, in particular in a continuous manner, electrostatically charged ink droplets in an original trajectory by means of a first deflecting device for deflecting the charged ink droplets in a plane out of the original trajectory, at least one second deflecting device being provided by which the ink droplets may be deflected in the same plane.
