摘要： A recording head is provided with a pressure chamber communicated with a nozzle orifice. A pressure generating element generates pressure fluctuation in ink contained in the pressure chamber. A drive signal generator generates a drive signal for driving the pressure generating element such that a main ink droplet and a satellite ink droplet accompanied with the main ink droplet are ejected to form an ink dot on a recording medium. The main ink droplet has a first volume, and the satellite ink droplet has a second volume which is larger than the first volume. Alternatively, the main ink droplet is ejected with a first speed, and the satellite ink droplet is ejected a second speed which is faster than the first speed.

摘要： A liquid jetting apparatus of the invention includes a pressure chamber having an inside space whose volume is changeable, into which a liquid is supplied and which is communicated with a nozzle. A Helmholtz resonance frequency of the pressure chamber has a period of TH. A signal-generating unit generates a driving signal, which includes a first signal-element for causing the pressure chamber to expand, a second signal-element for causing the pressure chamber to contract from an expanded state thereof in order to jet a drop of the liquid through the nozzle, and and a third signal-element for causing the pressure chamber to expand to an original state before outputting the first signal-element after the drop of the liquid is jetted. A pressure-generating unit causes the pressure chamber to expand and contract, based on the driving signal. An interval between a starting time of outputting the first signal-element and a starting time of outputting the second signal-element and an interval between a starting time of outputting the second signal-element and a starting time of outputting the third signal-element are set substantially equal to the period TH of the Helmholtz resonance frequency. A sum of an amplitude of the first signal-element and an amplitude of the third signal-element is set substantially equal to an amplitude of the second signal-element.
