Patent ID: 8096633

Claim:
A liquid droplet ejecting apparatus capable of selectively ejecting, through each of a plurality of nozzles, a type of droplet among a plurality of types of droplets each having a different droplet volume, comprising: a first storage unit storing therein information on the plurality of types of droplets; a second storage unit which stores therein time-sequence information of a type of droplet, where the time-sequence information associates each ejection timing of each of the nozzles with one of the types of droplets stored in the first storage unit; and a droplet type determination unit which determines a type of droplet to be associated with an arbitrary ejection timing of each of the nozzles, with reference to an ejection plan of the nozzle and a type of droplet associated with the arbitrary ejection timing of another nozzle, the ejection plan including types of droplets associated with the arbitrary ejection timing and at least one of the preceding and following ejection timings according to the time-sequence information.
