ABSTRACT:
In an ink-jet recording apparatus having two recording modes having different resolutions in recording, high density is realized in each of the recording modes in an excellent state. In a high-resolution recording mode, a colorless processing liquid to cause ink and its color material to be insoluble or to agglomerate is discharged, and the processing liquid and the ink are mixed on a recording medium. Thus, the ink becomes insoluble and therefore does not penetrate deeply into the recording medium, so that dots formed by the ink have a smaller diameter. As a result, high-resolution recording with the small-diameter dots can be realized. In a low-resolution recording mode, the diameter of dots formed by the ink without using the processing liquid is larger than in the foregoing case. Accordingly, dots can be densely arranged in the two modes, so that high density can be realized in an excellent state.
