Abstract: A method and an apparatus for generating color reappearance peculiarity profile and a method and an apparatus for reappearing color using a plurality of color reappearance peculiarity profiles are provided. The method of generating the color reappearance peculiarity profile includes: outputting a color standard scale having a set color information value through a color reappearance device; measuring actual color information value of the outputted color standard scale; calculating a color information difference value between the set color information value and the measured actual color information value of the color standard scale; and generating the color reappearance peculiarity profile which instructs the color reappearance device to reappear an optimized color using the color information difference value. Thus, the color reappearance optimized for a color reappearance device such as a color printer, a color copying machine, a monitor, or a scanner is performed by generating optimized color profiles.

Abstract: A print density setting method for image-forming apparatuses is disclosed. The print density setting method for an image-forming apparatus capable of forming an image based on at least three or more color data and black data comprises steps of, when the image is formed in monotone, setting a combination ratio of data for a composite black created based on a mixing of the three colors, to the data for the black color; and setting print density of the image to be formed based on the black data in the set combination ratio. Such a print density setting method can vary the density of an image created according to user's taste, and, when a user wants to minimize the ink consumption amount, the user sets the consumption amounts of the color ink and the black inks.
