Abstract
A liquid discharge apparatus is configure to drive nozzles with drive waveforms with which timing of discharge pulses fall within a range where a condition |A−C|<|B−D| is satisfied, where 'A' is a discharge velocity of a droplet having a first size when drive units are driven to discharge a droplet having the first size, 'B' is a discharge velocity of a droplet having a second size larger than the first size when drive units are driven to discharge a droplet having the second size, “C” is a discharge velocity of a droplet having the first size when drive units are driven to discharge droplets having the first size and the second size, and “D” is a discharge velocity of a droplet having the second size when drive units are driven to discharge droplets having the second size and the first size.
