Patent ID: 8733875

Claim:
A liquid discharge apparatus comprising: a movable head having a nozzle line with nozzles arranged in a predetermined direction; and a control unit which controls the movable head so as to cause the movable head to be moved in the predetermined direction and a direction perpendicular to the predetermined direction and which causes the movable head to perform a first liquid discharge process and a second liquid discharge process, which both sequentially form dots on a medium by intermittently discharging liquid from the nozzles while moving the head, the second liquid discharge process discharging liquid from the nozzles so that the dots formed during the second liquid discharge process are positioned between dot formation positions of the dots formed in the first liquid discharge process in the direction perpendicular to the predetermined direction, wherein the control unit moves the moveable head in both the predetermined direction and a direction perpendicular to the predetermined direction during of one of the first liquid discharge process and the second liquid discharge process such that a line of sequential dots formed on the medium during the one of the first liquid discharge process and the second liquid process are not parallel to a line of sequential dots formed during the other of the first liquid discharge process or the second liquid discharge process, wherein the control unit moves the moveable head such that a moving direction in which the moveable head is moved during the first liquid discharge process is symmetric with respect to the perpendicular direction or the predetermined direction to a moving direction in which the moveable head is moved during the second liquid discharge process.
