Therefore, the equipment has a plurality of ranges and strong and weak radiation targets can be measured.

For obtaining a color reproduction range of a printer closer to the color reproduction range of the positive film, a mere addition of a specific color recording material in the same manner as the recording materials of other colors is insufficient, and, for a specific color showing a large gap from the color reproduction range of the positive film, a different application amount different from the recording materials of other colors is required for such specific color, in consideration of color developing property. Therefore, in case of forming an image on a recording medium with recording materials of basic colors of cyan, magenta and yellow and recording materials of specific colors different in hue from such basic colors, a maximum application amount per unit area is made larger in at least a recording material of specific color than the application amount of the recording materials of the basic colors.
