Abstract:
1. An inkjet recording method for producing a black image on a recording medium by using an ink set having two or more types of ink compositions including at least one black ink composition and at least one color ink composition, wherein the recording medium has a recording surface with a 20-degree specular gloss value of 10% or larger, the 20-degree specular gloss value being a reflectance in proportion to 5% reflectance (100%) at a 20 degree incidence angle relative to a recording medium having a 1.567 refractive index, and an image clarity value of 15-95%, the image clarity value being an appearance of an object reflected on a paper surface; and wherein the discharged weight of the black ink composition upon producing the black image is 5-10 weight % in proportion to the total discharged weight (100 weight %) of the ink composition discharged upon producing the black image.
