Abstract
A fluid ejecting apparatus includes a nozzle row in which a plurality of nozzles that eject fluid onto a medium are arranged, a first movement unit that displaces a relative position between the medium and the nozzle row, and a control unit that forms a plurality of dot-lines by repeating a fluid ejection operation in which fluid is ejected so as to form a dot-line, such that a maximum time between when one of the adjacent dot-lines in the plurality of dot-lines is formed to when the other of the adjacent dot-lines is formed is reduced.
Claims13
A fluid ejecting apparatus comprising:
- a nozzle row in which a plurality of nozzles that eject fluid onto a medium are arranged, each nozzle row extending in a nozzle row direction;
- a first movement unit that displaces a relative position between the medium and the nozzle row in a cross direction that intersects with the nozzle row direction;
- a second movement unit that displaces the relative position between the medium and the nozzle row in the nozzle row direction;
- and
- a control unit that forms a plurality of dot-lines by repeating a fluid ejection operation in which the relative position in the cross direction is displaced while fluid is ejected so as to form a dot-line and a displacement operation in which the relative position in the nozzle row direction is displaced, the control unit controlling the fluid ejection operation and the displacement operation to form adjacent contiguous dot-lines in the plurality of dot-lines such that a timing difference between passes of nozzle row which forms the adjacent contiguous dot-lines is smaller than in the case where the plurality of contiguous dot-lines are formed by ejecting fluid from adjacent contiguous nozzles in sequential order from one end of the nozzle row to the other end of the nozzle row.
A fluid ejecting method for use in a fluid ejecting apparatus including:
- a nozzle row in which a plurality of nozzles that eject fluid onto a medium are arranged, each nozzle row extending in a nozzle row direction;
- a first movement unit that displaces a relative position between the medium and the nozzle row in a cross direction that intersects with the nozzle row direction;
- and
- a second movement unit that displaces the relative position between the medium and the nozzle row in the nozzle row direction, wherein a plurality of dot-lines are formed by alternately repeating a fluid ejection operation in which the relative position in the cross direction is displaced while fluid is ejected so as to form a dot-line and a displacement operation in which the relative position in the nozzle row direction is displaced, the fluid ejecting method comprising:
- performing the fluid ejection operation and the displacement operation so as to form contiguous adjacent dot-lines in the plurality of dot-lines such that a maximum time between passes of nozzle row which forms the contiguous adjacent dot-lines is smaller than in the case where the plurality of contiguous dot-lines are formed by ejecting fluid from adjacent contiguous nozzles in sequential order from one end of the nozzle row to another.
