  • System And Method For Per Drop Electrical Signal Waveform Modulation For Ink Drop Placement In Inkjet Printing
    Publication number: 20140362135
    Abstract: A method for operating an inkjet printer includes identifying a pattern of ink drops ejected from an inkjet with reference to image data for a printed image, identifying a waveform component for an electrical signal operating the inkjet to eject an ink drop in the pattern of ink drops with reference to at least a portion of the image data, and generating the electrical signal with the identified waveform component to eject the ink drop in the pattern of ink drops at a first velocity onto a first location of an image receiving surface.
