Droplet ejecting device capable of increasing number of tones efficiently

摘要

A voltage-set-information storing section stores two or more kinds of voltage sets each including a combination of first and second voltages for each number of droplets ejected from an ejection port within a single recording cycle. A voltage applying section is configured to apply the first voltage to an active portion of a first piezoelectric layer and to apply the second voltage to an active portion of a second piezoelectric layer based on image data of the image. The voltage applying section is configured to select one of the two or more kinds of voltage sets stored in the voltage-set-information storing section and to apply each voltage constituting the selected voltage set to the active portions of the first and second piezoelectric layers. The voltage sets are classified by a degree of temporal overlapping of pulse-shaped voltages included in the first and second voltages.
