CPC B41J 2/04588 (2013.01) [B41J 2/04541 (2013.01); B41J 2/04551 (2013.01); B41J 2/04581 (2013.01)] | 8 Claims |
1. A liquid discharge apparatus comprising:
a discharge section that discharges droplets by supplying a driving signal;
a first wiring for transmitting a setting information signal group that has a first setting information signal and a second setting information signal and sets a rule for selecting a driving waveform applied to a piezoelectric element included in the discharge section from the driving signal, and a discharge control signal group that has a first discharge control signal and controls a gradation of dots formed by discharging the droplets from the discharge section;
a second wiring for transmitting the driving signal having the driving waveform; and
a selection circuit that switches whether or not to supply the driving signal to the discharge section based on the setting information signal group and the discharge control signal group, wherein
the apparatus is configured to be operated in a first print mode in which the droplets are discharged from the discharge section according to the setting information signal group and printing is performed with a first gradation number, and in a second print mode in which printing is performed with a second gradation number smaller than the first gradation number, and
in the second print mode, the droplets are discharged from the discharge section according to the first setting information signal and the second setting information signal in which bit data of the first setting information signal is inverted.
