ABSTRACT:
A liquid ejecting apparatus includes a first head having a first nozzle group in which nozzles from which a first liquid is ejected are aligned in a nozzle-row direction at a predetermined pitch and a second nozzle group in which nozzles from which a second liquid is ejected are aligned in the nozzle-row direction at the predetermined pitch, the nozzles in the first nozzle group being positioned between the nozzles in the second nozzle group in the nozzle-row direction; a second head having a third nozzle group in which nozzles from which the first liquid is ejected are aligned in the nozzle-row direction at the predetermined pitch and a fourth nozzle group in which nozzles from which the second liquid is ejected are aligned in the nozzle-row direction at the predetermined pitch, the nozzles in the third nozzle group being positioned between the nozzles in the fourth nozzle group in the nozzle-row direction; and a moving mechanism that moves the first head and the second head relative to a medium in a direction intersecting the nozzle-row direction. In the nozzle-row direction, the nozzles in the third nozzle group are positioned between the nozzles in the first nozzle group, and the nozzles in the fourth nozzle group are positioned between the nozzles in the second nozzle group.
