  • Inkjet printing with air movement system to improve dot shape
    Patent number: 6491364
    Abstract: An inkjet printer for printing on a print medium includes a printhead having an ink orifice formed therein through which an ink drop is ejected into a print zone between the printhead and the print medium during printing, and an air movement system which directs a stream of gas through the print zone as the ink drop is ejected during printing. When ejected, the ink drop forms a head and a tail. As such, the stream of gas converges the tail of the ink drop and the head of the ink drop during printing so as to improve the shape of a dot formed by the ink drop on the print medium.
