Patent ID: 11577538

Abstract:
An ink jet recording method includes a treatment liquid attachment step, in which a treatment liquid is attached to a recording medium, and an ink attachment step, in which a water-based ink composition is attached to the recording medium. An ink jet recording apparatus includes a recording medium support and a heating mechanism that heats the recording medium support. The ink attachment step is carried out with the recording medium supported and heated by the recording medium support. In the ink attachment step, the recording medium is heated so that a surface thereof reaches a maximum temperature of 28.0° C. or more and 45.0° C. or less. The ratio between absorbances A and B (A/B) is 0.5 or more and 0.95 or less, where absorbance A is that of a 0.1% by mass mixture of the water-based ink composition in the treatment liquid, and absorbance B is that of a 0.1% by mass mixture of the water-based ink composition in purified water. The recording medium support has a flat support surface for supporting the recording medium.
