Abstract:
An inkjet printer is configured to reduce the settling of magnetic particles in magnetic ink. The inkjet printer is configured to eject magnetic ink and black ink in areas where the corresponding image data only has black ink pixels. The printing of the magnetic ink in the black ink areas helps prevent the magnetic particles in the magnetic ink from settling.
