Title: SINGLE-PASS INKJET PRINTING
Abstract:
A print head has an array of ink orifices arranged to selectivelydeposit drops of ink along parallel print lines on the medium while the medium and the print head undergo relative motion in a printing direction parallel to the print lines, the printing being completed in a single pass of the print head relative the medium. The orifices in the array are arranged in a pattern such that adjacent parallel print lines on the medium are served by orifices that have different positions in the array along the direction of the print lines. The different positions of the orifices that serve any pair of adjacent parallel lines are separated by no less than a first predetermined distance along the direction of the print lines.
