  • Patent number: 8804219
    Abstract: An image processing apparatus is disclosed. The image processing apparatus includes a color conversion processing unit which obtains CMY data from input color space coordinate data of image data, and an output data generating unit which generates output data by forming CMYK data by using a result output from a color conversion processing section. The color conversion processing section includes an optimum color reproduction data structure which gives the CMY data for obtaining a full color image optimally reproduced from the input color space coordinate data, and a color material using amount reducing data structure for outputting the input color space coordinate data by reducing the color material using amount with the use of a reference value in which the color material using amount is increased for a hue of an output image giving a high psychological effect and is decreased for a hue of the output image giving a low psychological effect.

  • Patent number: 8730524
    Abstract: A disclosed image processing apparatus performs an image processing operation to execute double-side printing on both sides of an image forming medium. The image processing apparatus forms a dot font including a dot pattern of a character in a character image that has undergone a halftone process using a predetermined coefficient for mitigating show-through when the double-side printing is performed; forms a correction dot for making a correction to reduce step-like irregularities along an outline portion of the character in the character image, which correction dot is formed based on an arrangement position, a color, and a dot size of the correction dot for reproducing a gradation that has undergone the halftone process using said predetermined coefficient; and combines the dot font and the correction dot.
