Abstract
A liquid discharge apparatus includes a conveyance roller, a liquid discharge head, and a control device. The control device controls the head to discharge liquid onto a medium X times in the main scanning direction and Y times in the sub-scanning direction and controls the roller such that a position of a droplet on the medium discharged by an m-th discharge and a position of another droplet on the medium discharged by an (m+Y)-th discharge are same in the sub-scanning direction, where m is an integer not smaller than one and not greater than ((X−1)×Y). Where P is a circumferential length of the roller and L is a difference in a conveyance distance in the sub-scanning direction when the m-th discharge is compared with the (m+Y)-th discharge, the following relation is satisfied:=(+(Δθ/2π))×
