Abstract: A recording method includes heating a recording medium and attaching an ink composition including an organic solvent and water to the heated recording medium by performing a main scanning a plurality of times. In each main scanning the ink composition is ejected from a recording head while a position of the recording head relative to the recording medium in a main scanning direction is changed. In the ink composition, an absolute value of a difference between a surface tension of the ink composition and a surface tension of the ink composition when the ink composition is evaporated up to an evaporation amount of 0% to 40% by mass is 1 mN/m or less.

Abstract: An ink jet recording method is provided for recording white and non-white ink compositions onto a moving recording medium. The recording medium includes a first region where both the white and non-white ink compositions are adhered, and a second region where only the white ink composition is adhered. Further, one or both of Conditions (i) and (ii) is satisfied. Condition (i): The amount of the white ink composition adhered in the first region is less than the amount of the white ink composition adhered in the second region. Condition (ii): The number of times the white ink composition is scanned across the first region is less than the number of times the white ink composition is scanned across in the second region.

Abstract: According to the invention, there is provided a recording method which includes discharging and adhering a reaction liquid to an ink non-absorbable or ink low-absorbable recording medium in a form of a droplet, by using an ink jet method, the reaction liquid containing a reagent for aggregating or thickening of a colored ink composition, so as to have a content of 0.1 mol/kg to 0.9 mol/kg, and the reaction liquid having an adhering amount which is set to be equal to or smaller than 1.9 mg/inch2, and adhering a colored ink composition to the recording medium to which the reaction liquid has adhered. A period from when adhering of the reaction liquid is ended until adhering of the colored ink composition is started is within 30 seconds. A surface temperature of the recording medium from the adhering of the reaction liquid to the adhering of the colored ink composition is equal to or lower than 38° C.
