ABSTRACT:
A liquid ink printer, depositing ink to form an image having a first resolution on a recording medium moving in a first direction, including a scanning carriage moving along a carriage rail in a scanning direction substantially transverse to the first direction. The printer includes a liquid ink printhead, coupled to the scanning carriage, including ink ejectors spaced at a second resolution, different from the first resolution, and a moving device, coupled to the printhead, moving the printhead in the first direction. The printhead is moved in the second direction to deposit a first swath of ink on the recording medium. The printhead is then moved in the first direction, and again moved in the second direction to deposit a second swath of ink on the recording medium, the first swath and the second swath overlapping. The printhead is moved in the first direction by either moving the carriage rail or by moving the scanning carriage with respect to the carriage rail by a distance approximately equal to one-half the distance between adjacent ink ejectors.
