Abstract: Utilizing an ink set that includes a plurality of chromatic primary color inks that, when used in combination, can reproduce achromatic color, and at least one spot color ink of hue different from any of the plurality of chromatic primary color inks. Color to be reproduced on a print medium according to any one input color is termed “reproduction color”, and the combination of ink quantities in the ink set for reproducing the reproduction color on the print medium is termed the “color separation ink quantity set.” The ink quantity of the spot color ink included in the color separation ink quantity set is adjusted in accordance with a lightness parameter value which is correlated to lightness of reproduction color, so as to reduce ink quantity at a rate of change greater than the rate of change of the lightness parameter in the direction of increasing brightness.

Abstract: Image quality is improved by adjusting the ejection amount of quality enhancing ink based on the ejection amount of colored ink containing colorant. When a relatively high gross printing medium is used, the quality enhancing ink is ejected in an image area where virtually no colored ink is ejected, thereby improving unevenness in gloss within the print image. When a relatively low gross printing medium is used, on the other hand, the quality enhancing ink is ejected in an image area where the colored ink is ejected on virtually all pixels, thereby improving unevenness in color within the print image. The relationship between the ejection amounts of the quality enhancing ink and the colored ink may be modified by the user.

Abstract: For correlating the specified colors and ink amount, the specified color data showing the color values of the specified colors are acquired, the ink amount data showing optional ink amount are converted into color values, evaluation index including the first evaluation index for evaluating the color difference between the color value of the specified colors under the standard observation condition and the color value of the ink amount and the second evaluation index for evaluating the color difference among color values obtained under a plurality of observation conditions are acquired, the question of whether the evaluation by the evaluation index meets the predetermined evaluation standard or not is evaluated, the conversion of the ink amount data and the acquisition of the evaluation index are repeated by correcting the ink amount until the evaluation standard is met, and the ink amount data of the ink amount having met the evaluation standard and the specified color data are correlated.

Abstract: A look up table LUT with specific gray reproduction characteristics is used for converting RGB image data to multi-tone data of ink colors. The gray reproduction characteristics of LUT are set such that the color difference ?E of a gray color area with an arbitrary tone level in the L*a*b* color system is kept at about 4 or less, assuming that the results are observed under two different light sources, such as standard light D50 and standard light A, respectively.

Abstract: An image processing device and image processing method maintain hue and prevent a drop in print quality while also reducing consumption of recording materials. For example, a host computer 3 that outputs output data for printing to a inkjet printer 2 that uses cyan (C), magenta (M), and yellow (Y) inks has a drawing unit 210 that acquires bitmap data expressing the density of each channel in each pixel of an image to be printed, a density adjustment parameter setting unit 250 that sets an adjustment value according to the ink deposition level when the ink deposition level setting ink usage is received, a density adjustment unit 220 that adjusts the density of the bitmap data to a density corresponding to the set adjustment value, a color conversion unit 230 that converts the density-adjusted bitmap data to CMY image data expressing the usage of each ink, and a halftone processing unit 240 that generates the output data based on the CMY image data.

Abstract: An ink set that includes a plurality of chromatic primary color inks that can reproduce achromatic color in combination with each other and at least one spot color ink having a hue different from any of the chromatic primary color inks is prepared. A color to be reproduced on a printing medium in accordance with a given input color is termed a reproduction color, and a combination of ink amounts for inks in the ink set to be used to reproduce the reproduction color on the printing medium is termed a color separation ink amount set. When a saturation parameter value that is correlated with the saturation of the reproduction color falls within a first range that is close to achromaticity, the ink amount of the spot color ink included in the color separation ink amount set is adjusted such that it decreases in accordance with a change in the saturation parameter value in the direction of lower saturation.

Abstract: The ratio of ink quantities for reproducing achromatic color by a mixture of primary color inks is termed primary color mixture ratio. A primary coloring factors correlated to the primary color mixture ratio is established for each primary color ink. The ratio of each ink quantity is adjusted based on the primary coloring factor.

Abstract: A second printing control unit is provided. If the setting information is the information of setting for avoiding the use of Cl ink (uncolored ink), the second printing control unit refers to the same color conversion table as is used by a first printing control unit. Thereby the second printing control unit color-converts input image data into image data comprising gradation data corresponding to at least the amounts of colored inks in C, M, Y, R, V, and K consumed. The second printing control unit can carry out such control as to cause a printer (printing device) to use only the C, M, Y, R, V, and K colored ink and print a print image, using the image data.
