ABSTRACT:
A liquid jetting apparatus and a liquid jetting method are achieved that can prevent unexpected landing position displacement relating to satellite droplets. For example, the liquid jetting apparatus includes a head in which a nozzle row constituted by a plurality of nozzles lined up in a row is arranged at a medium-opposing surface which is in opposition to a medium, a head movement section that moves the head in a predetermined direction along a surface of the medium, a spacing adjustment section that adjusts a spacing between the head and the medium, and an ejection control section that carries out ejection control of a liquid by determining at least one non-ejection nozzle among a plurality of nozzles sandwiched between a nozzle at one end of the nozzle row and a nozzle at another end thereof, the non-ejection nozzle being a nozzle which is caused not to eject liquid, the number of the non-ejection nozzle being determined according to a spacing from the medium-opposing surface to the surface of the medium.
