Patches at grid points in a color space corresponding to a plurality of colorants at which the total colorant amount falls within a restriction represented by the restriction information, and a patch at a point surrounded by the patches are generated. Color values are obtained by measuring the colors of the patches printed on the medium. It is determined based on a color prediction value between the grid points whether the measured color values are appropriate, and if so, a color value at a grid point at which the total colorant amount exceeds the restriction is estimated based on the measured color values. A color separation table is created based on the measured color values and the estimated value. | 2009-04-02 |
20090086226 | IMAGE FORMING SYSTEM, IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image forming system supplied capable of keeping a high thruput when performing a background pattern data print (e.g. Anoto print). The image forming system comprises a color image processing apparatus and a color image forming apparatus that is connected with the color image processing apparatus, wherein the color image processing apparatus has a color changing section that uses one of CMYK values to designate background pattern data when performing a CMYK change with respect to color image data generated in the color image processing apparatus; wherein the color image forming apparatus has an image forming section that receives the color image data that has been performed by the CMYK change and the background pattern data that has been designated by one of CMYK values from the color image processing apparatus, and compounds the both data to form an color image. | 2009-04-02 |
20090086227 | DEVICE FOR CHANGING SCREEN RULING FOR IMAGE FORMATION IN ACCORDANCE WITH RELATIONSHIP BETWEEN LUMINANCE AND SATURATION - The present invention relates to a device that, in printing of controlling the amount of color materials applied, changes a screen ruling for image formation according to the relationship between luminance and saturation. A first component obtains color component data of a plurality of colors so that the total amount of controlled variable in each pixel does not exceed a first limit amount. A second component obtains color component data of a plurality of colors so that the total amount of controlled variable in each pixel does not exceed a second limit amount by performing color conversion processing different from the color conversion processing with the first component. A third component performs pseudo halftone processing by changing a screen ruling to be applied to the color component data of a plurality of colors obtained by the color conversion processing with the second component from chromaticity of color image data. | 2009-04-02 |
20090086228 | COLOR CONVERSION DEVICE, PROGRAM, AND METHOD - A color conversion device converts an input value to an output value in order to form an image on a recording medium using an achromatic ink and a chromatic ink. The color conversion device include a first color converting unit, a second color converting unit, an adjustment value setting unit, and an output value acquiring unit. The first color converting unit converts the input value to first color data including a first chromatic component value. The second color converting unit converts the input value to second color data including a second chromatic component value and a first achromatic component value. The adjustment value setting unit sets an adjustment value based on a type of the recording medium. The output value acquiring unit acquires the output value by weighting the first color data and the second color data according to the adjustment value. | 2009-04-02 |
