Patent ID: 7419232

Claim:
An inkjet printer comprising: a plurality of recording heads for jetting inks of a plurality of kinds onto a recording medium; a light emitting device for irradiating light onto ink having reached the recording medium; a driving device for moving the plurality of recording heads and the recording medium relatively and bidirectionally; and a control device for performing control to form an image by controlling the plurality of recording heads to jet ink while moving the plurality of recording heads and the recording medium relatively in one direction and in an opposite direction, and changing ink jetting amounts to be jetted from the respective recording heads, depending on whether jetting ink while the recording heads are moving in the one direction or in the opposite direction, so that a same color is formed in both of the moving directions of the recording heads, wherein the control device performs control such that at least one of the plurality of recording heads jets a first ink directly onto the recording medium and the light emitting device cures the first ink while the plurality of recording heads and the recording medium are relatively moving in the one direction, and such that at least one of the plurality of recording heads jets a second ink onto the recording medium having the already cured first ink thereon and the light emitting device cures the second ink while the plurality of recording heads and the recording medium are relatively moving in the opposite direction; and wherein the control device changes an ink jetting amount depending on whether jetting the ink while the recording heads are moving in the one direction or in the opposite direction, corresponding to respective ink wettabilities and a wettability of the recording medium.
