Abstract
A liquid discharge apparatus includes a discharge device, a driving device, processing circuitry, and a reading device. The discharge device discharges liquid to a recording medium to form a test pattern. The driving device causes the discharge device to discharge the liquid according to a driving waveform. The processing circuitry inputs a plurality of driving waveforms and acquires first data indicating a standard pattern that corresponds to the driving waveform and is formed with the driving waveform or indicating a parameter of the standard pattern. The reading device reads the test pattern to generate second data. The processing circuitry compares the second data with the first data and selects a driving waveform generating a smallest difference between the second data and the first data, based on a result of comparison of the second data with the first data.
