Abstract
In an inkjet printer capable of performing an overprint process by feeding only in a first direction while reducing clogging of nozzles, a controller includes first, second and third controllers. The third controller instructs the first controller to perform a first image-printing scan, a first minute feed and a second image-printing scan without discharging an image ink from a first nozzle at an end portion of a first nozzle row in a first direction along a secondary scan direction; then performs a second minute feed of feeding a recording medium in the first direction along the secondary scan direction relative to a discharge head; and then instructs the second controller to perform a first base-printing scan, a first minute feed and a second base-printing scan without discharging a base ink from a second nozzle at an end portion of a second nozzle row in a second direction, opposite to the first direction, along the secondary scan direction.
