Abstract:
1. An image recording apparatus comprising: a recording nozzle group capable of discharging three or more types of ink; a driving means for moving the recording nozzle group relatively with respect to a recording medium; an image brightness signal inputting means for inputting input image information as three or more types of image brightness signals; a ink type distribution process means for sorting the image brightness signals, which are input by the image brightness signal inputting means, into image density signals that correspond to each of the inks; and a recording and controlling means for recording an image onto the recording medium by causing the three or more types of ink to be discharged from the recording nozzle group based on the image density signals for each ink which are sorted by the ink type distribution process means; wherein the three or more types of ink have a certain relationship between a lightness organization for each color ink in a color ink set when the recording apparatus is used as a color printer, and a density organization for each monotone ink of a monotone ink set when the recording apparatus is used as a monotone printer.
