Abstract:
An ink jet recording method that uses an ink set including a black ink and a plurality of color inks, at least one of the plurality of color inks containing a metal ion and being a reactive color ink that exhibits mutual reactivity with the black ink, each color ink other than the at least one reactive color ink being a non-reactive color ink that exhibits non-reactivity with the black ink, the ink jet recording method comprising:a step for applying the at least one reactive color ink in an area in which the metal ion becomes effective at promoting a reaction between the black ink and the at least one reactive color ink, wherein the at least one reactive color ink is applied in the area so that a value at least equal to 0.01 is obtained from a calculation where the metal ion concentration percentage by weight in the at least one reactive color ink applied in the area is multiplied by a print duty percentage of the at least one reactive color ink applied in the area.
