Abstract
An ink jet recording apparatus includes an ink jet head in which nozzles ejecting aqueous pigment ink in accordance with gradation are arrayed, a sub scanning driving unit which carries a recording medium having an image formed thereon with the ink, a heating unit which selectively heats an area divided into an integral multiple of a minimum recording pixel in the recording medium, and a heating control unit which determines presence and absence of an image based on image information recorded to the recording medium, and controls the heating unit.
Claims20
An ink jet recording apparatus comprising:
- an ink jet head in which nozzles ejecting aqueous pigment ink in accordance with gradation are arrayed;
- a sub scanning driving unit which carries a recording medium having an image formed thereon with the ink;
- a heating unit which selectively heats an area divided into an integral multiple of a minimum recording pixel in the recording medium;
- and
- a heating control unit which determines presence and absence of an image based on image information recorded to the recording medium, and controls the heating unit.
An ink drying method comprising:
- carrying a recording medium on which an image is formed by ejecting aqueous pigment ink from nozzles of an ink jet head in accordance with gradation;
- determining presence or absence of an image based on image information recorded to the recording medium;
- and
- selectively heating an area divided into a integral multiple of a minimum recording pixel in the recording medium.
An ink jet recording apparatus comprising:
- means for ejecting aqueous pigment ink in accordance with gradation, from an ink jet head having nozzles arrayed therein;
- means for carrying a recording medium having an image formed thereon with the ink;
- means for selectively heating an area divided into an integral multiple of a minimum recording pixel in the recording medium;
- and
- means for determining presence and absence of an image based on image information recorded to the recording medium, and controlling the selective heating.
