ABSTRACT:
An improved ink jet recording interlace strategy. Sequentially generated ink droplets directed to a recording medium are first charged and deflected by a uniform electric field. The charge sequence on the droplets is such that the droplets are separated by the electric field as they travel toward the medium thereby reducing electrostatic and aerodynamic interactions between droplets. The separation of droplets conforms to an interlace scheme wherein droplets directed to closely adjacent recording medium locations are separated by a number of droplets whose placement of said medium conforms to a multi-level interlace such that the scan direction of the number of droplets is disrupted at least once. In this way, sequentially generated droplets are directed to non-sequentially pixel locations in non-sequential interlace portions of the total number of adjacent pixel locations assigned to a particular nozzle.
