Abstract
Provided is an ink image matter generating method for selecting a fluorescent ink by performing (a) a process of color-measuring a target color which is a target of color reproduction on a medium and the medium on which an inkjet color ink for color reproduction of the target color is printed; (b) a process of calculating a difference between a colorimetric value of the target color and a colorimetric value of the medium on which the color ink is printed; and (c) a process of selecting a fluorescent ink for reducing the difference between the colorimetric value of the target color and the colorimetric value of the medium on which the color ink is printed, from fluorescent inks that are set in advance, and jetting droplets of the selected fluorescent ink together with the color ink, or after the droplets of the color ink are jetted to cause the fluorescent ink to exist on a surface of an ink image matter, thereby making it possible to select and use an appropriate fluorescent ink with respect to a specific color of which the color reproducibility cannot be ensured using only a color ink in inkjet printing on a medium which is a printing substrate and to ensure high color reproducibi…
