The printing method employs the printting device which has a ink jet head. The ink jet head has a nozzle row having a plurality of nozzles for jetting black color ink and a nozzle row having a plurality of nozzles for jetting color ink. The method comprises: acquisition step, acquiring image data of an image printed on a medium; a jet step, jetting black ink to the medium based on the image data; and a jetting step, jetting color ink on the medium based on the image data, wherein the supply ability of a black ink supply unit is higher than that of a color ink supply unit.
