Abstract (en)

A liquid discharge apparatus includes a rotating member (21) that conveys a sheet material (P) by holding the sheet material on a peripheral surface of the rotating member, a liquid discharge device (23A to 23F) that discharges liquid on the sheet material, a sheet material position detecting unit (220) that detects a position of the sheet material, a first signal output unit (201) that outputs a first signal in accordance with a rotation amount of the rotating member, a second signal output unit that outputs a second signal that is correlated with a movement amount of the sheet material on the peripheral surface of the rotating member, a correction data storage unit that stores correction data, which corrects the second signal, obtained based on the first signal and the second signal, and a discharge timing generating unit that generates a discharge timing of the liquid discharge device based on the second signal and the correction data.
