Abstract
A liquid discharge apparatus includes a conveyor, a liquid discharge unit, a reader, and circuitry. The conveyor conveys a recording medium in a conveyance direction. The liquid discharge unit forms an image on the recording medium. The reader reads the image. The circuitry causes the liquid discharge unit to form a mark image on the recording medium, causes the reader to read the mark image to obtain read information, corrects an image to be formed based on the read information, and causes the liquid discharge unit to form the image, corrected based on the read information, on the recording medium. The mark image includes a first mark image including two or more vertical lines extending in the conveyance direction and two or more horizontal lines extending in a width direction. Each of the two or more vertical lines intersects or contacts each of the two or more horizontal lines.
