Abstract: Provided are a control apparatus, an image processing method and a non-transitory recording medium. A hardware processor of the control apparatus controls the amount of color materials to be used in printing a source image together with a white base by adjusting pixel values of multi-valued pixels forming the source image and white base, and converts the multi-valued pixels into two-valued pixels corresponding to colors of the color materials of the source image and two-valued white pixels. In controlling the amount of color materials, the hardware processor, for each multi-valued pixel of the white base, defines the pixel value such that colored two-valued white pixels exist in a coverage ratio being equal to or greater than the total coverage ratio of the color materials of the source image. The hardware processor rearranges the two-valued white pixels so that colored two-valued white pixels are located at all the colored pixel positions.

Abstract: Provided are a profile creation apparatus, a non-transitory computer-readable storage medium storing a profile creation program and a profile creation method. The profile creation apparatus includes a standard-color-profile obtaining section that obtains a standard color profile and a reference-device-profile obtaining section that obtains a reference-device profile. The profile creation apparatus further includes a color-conversion-table creation section that creates a color conversion table by combining the standard color profile and reference-device profile with being weighted such that a weighed ratio of the standard color profile increases as chroma calculated from input color values of the color conversion table increases, in a predetermined chroma region. The profile creation apparatus further includes a color conversion section that performs color conversion on a print image by using the color conversion table and outputs the print image to a certain printing device.

Abstract: There is provided a color printing system including: a specification unit that specifies an area which has predetermined colors from printing target image data; a printing unit that prints the image data; a color measurement unit that measures the colors of the area, which is specified by the specification unit, with regard to a printed matter; a recording unit that records color measurement results whenever the image data is printed; and a color adjustment unit that, when a predetermined number of color measurement results of the predetermined colors are completed, executes color adjustment using the color measurement results. Therefore, it is possible to prevent accuracy from being lowered while the color adjustment is effectively executed.

Abstract: A color adjusting system (1) of the present invention applies separate pieces of correcting data to a single color chart and a mixed color chart, respectively, and prints both charts on one sheet. Therefore, when this print result is observed, it is possible to confirm whether a single color is appropriately corrected and also to determine whether a mixed color needs to be corrected. When no color adjustment is necessary for the mixed color, it is not necessary to prepare a mixed color chart afterwards. Accordingly, unnecessary printing or color adjustment is not performed, which enables to perform an efficient color adjustment.
