  • Optimizaton of dot placement for thermal drift
    Patent number: 8282193
    Abstract: A method of printing executes a software instruction using a print system controller to measure a vertical position of each row of an array of jets, having at least one offset subset of the array offset in a movement direction, adjusts timing of firing intervals for the offset subset such that the offset subset fire after a longer interval than other jets, and fires jets other than the offset subset at a predetermined firing interval. A print head has an array of transducers, an ink chamber to store ink arranged adjacent the array of transducers, and an array of jets arranged adjacent the ink chamber such that when selected ones of the array of transducers are activated, ink from the chamber exits a jet corresponding to the selected ones of the transducers, the array of jets having at least one subset of the array offset in a vertical direction relative to the other jets.
