Claim Text:
1. A liquid droplet ejecting apparatus comprising: a recording head that includes a first nozzle set through which a first liquid is ejected onto a dot recording medium, and a second nozzle set through which a second liquid different from the first liquid is ejected onto the dot recording medium; a scanning driving portion that performs bidirectional scanning for an outward path and a return path by moving at least one of the dot recording medium and the recording head; and a control portion that controls the scanning driving portion and the recording head, wherein the control portion executes multi-pass recording that completes dot recording on each of a plurality of scanning lines by executing N scan passes including a scan pass for the outward path and a scan pass for the return path (N being an integer of 2 or more), and when a proportion of executions of dot recording using the first liquid in each of the N scan passes is made a first recording ratio, and a proportion of executions of dot recording using the second liquid in each of the N scan passes is made a second recording ratio, the control portion sets the first recording ratio and the second recording ratio such that, in a first half of the N scan passes, a total ratio of the first recording ratio is larger than a total ratio of the second recording ratio, and in a second half of the N scan passes, a total ratio of the second recording ratio is larger than a total ratio of the first recording ratio.
