Abstract
A liquid discharge apparatus includes a plurality of nozzle arrays and circuitry. The nozzle arrays discharge a plurality of droplets having different volumes onto a recording medium at mutually different times. The circuitry controls a discharge operation to discharge the droplets. The circuitry causes a nozzle array of the nozzle arrays to discharge a droplet, of the droplets, of a first reference amount, and causes another nozzle array of the nozzle arrays to discharge a droplet, of the droplets, of a second reference amount greater than the first reference amount to land later than the droplet of the first reference amount.
Claims14
A liquid discharge apparatus comprising:
- a plurality of nozzle arrays to discharge a plurality of droplets onto a recording medium at mutually different times, wherein the plurality of nozzle arrays are located at different positions in a first direction, and the plurality of nozzle arrays include a plurality of nozzles aligned in a second direction intersecting the first direction;
- and
- circuitry configured to control a discharge operation to discharge the plurality of droplets,
- the circuitry being configured to:
- cause a nozzle array of the plurality of nozzle arrays to discharge a small droplet, of the plurality of droplets, of a first reference amount;
- cause another nozzle array of the plurality of nozzle arrays to discharge a large droplet, of the plurality of droplets, of a second reference amount greater than the first reference amount to land later than the small droplet of the first reference amount;
- and
- discharge the small droplet to land on one of a first position and second position adjacent to each other in the first direction on the recording medium before discharging the large droplet to land on another one of the first position and the second position.
A liquid discharging method for causing a plurality of nozzle arrays to discharge a plurality of droplets onto a recording medium at mutually different times, wherein the plurality of nozzle arrays are located at different positions in a first direction, and the plurality of nozzle arrays include a plurality of nozzles aligned in a second direction intersecting the first direction, the method comprising:
- causing a nozzle array of the plurality of nozzle arrays to discharge a small droplet, of the plurality of droplets, of a first reference amount;
- causing another nozzle array of the plurality of nozzle arrays to discharge a large droplet, of the plurality of droplets, of a second reference amount greater than the first reference amount to land later than the small droplet of the first reference amount;
- and
- discharging the small droplet to land on one of a first position and second position adjacent to each other in the first direction on the recording medium before discharging the large droplet to land on another one of the first position and the second position.
