Abstract
There is provided a liquid discharge apparatus including: first and second liquid discharge heads and a controller. The first liquid discharge head includes n of nozzles NA1-NAn and m of nozzles NB1-NBm. The second liquid discharge head includes m of nozzles NC1-NCm. The first and second liquid discharge heads include m of nozzle pairs (NB1, NC1)-(NBm, NCm) A difference of position between the nozzle NBj and the nozzle NCj in the first direction is smallest in the j-th nozzle pair (NBj, NCj), of them of nozzle pairs (NB1, NC1)-(NBm, NCm), and a difference between the use rate RBp of the nozzle NBp and the use rate RCp of the nozzle NCp is smallest in the p-th nozzle pair (NBp, NCp) different from the j-th nozzle pair (NBj, NCj), of the m of nozzle pairs (NB1, NC1)-(NBm, NCm).
