Abstract: A liquid discharge apparatus includes multiple liquid discharge heads, a medium mover, and circuitry. The multiple liquid discharge heads include a first liquid discharge head to discharge a treatment liquid onto a region of the medium and a second liquid discharge head to discharge a color liquid onto the region to paint the region, on which the treatment liquid is applied, in a predetermined color. The circuitry causes the first and second liquid discharge heads to form an evaluation chart. The evaluation chart includes patterns different in a combination of a first discharge amount of the treatment liquid and a second discharge amount of the color liquid. Further, the circuitry performs a setting of the first discharge amount with respect to the second discharge amount according to the coloring, and causes the second liquid discharge head to discharge the treatment liquid onto the region based on the setting.

Abstract: A liquid discharge apparatus includes a head, a holder, a remover, a charger, a static eliminator, and a cleaner. The head discharges a liquid onto a medium to perform printing on the medium. The holder holds the head. The remover is disposed on the holder to remove a foreign substance on the medium. The charger charges the remover before the printing. The static eliminator eliminates static electricity from the remover after the printing. The cleaner cleans the remover after the static electricity has been eliminated therefrom.
