There are provided a spectral reflectivity estimating unit which estimates spectral reflectivity of a mixed color created by use of a second color material group different from a first color material group on the basis of spectral reflectivity of each of color materials of the second color material group as a mixed-color source and a use ratio of the color materials of the second color material group in the mixed color; a color material set estimating unit which estimates the color material amount set for reproducing spectral reflectivity approximate to the spectral reflectivity of the mixed color on a print medium; and a printing control unit which permits a printing apparatus to perform printing on the basis of the estimated color material amount set.

The table 200 represents that only small dots should be formed in the range Cd1 of relatively small tone values. In the range Cd2, the production rate of small dots gradually decreases, while the production rate of medium dots increases. In the range Cd3, the production rate of small dots and medium decreases, while the production rate of large dots increases. Consequently, small dots, medium dots, and large dots are intermingled, with the proportion of large dots increasing in association with higher tone values. According to the present invention, printing is able to be implemented while switching among dot apportionment tables depending on the object represented in one set of image data, and printing using small dots is able to be implemented efficiently in areas where low grainy appearance is required, namely areas corresponding to human faces.

When creating recording level specifying data referred to during recording of ink drops of N types (N is an integer of 2 or greater) of different ink levels onto a printing medium by a printing device, standard color value data indicating an association relationship between ink tone values and color values under a standard printing condition is acquired; under a predetermined printing condition, and using at least one type of the aforementioned N types of ink drops for each ink color, patches are printed at a plurality of recording levels, and the color values of the printed patches are acquired; the aforementioned plurality of recording levels are associated with color values; and on the basis of association of the aforementioned plurality of recording levels and color values and of the aforementioned standard color value data, there is created recording level specifying data that specifies, for each ink color, an association relationship recording levels of the aforementioned N types of ink drops and tone values under the aforementioned predetermined printing condition.
摘要:
A plurality of color conversion profiles are prepared for each of plural types of color conversion profiles. One profile is selected for each of the color conversion profile types according to the printing mode used when printing, and color conversion is performed by sequentially using the selected color conversion profiles, without combining these selected color conversion profiles.

A printer driver causes a computer to perform a function of printing by attaching a color material to a recording medium. The printer driver causes a computer to perform: an image displaying function of displaying an image; a region designating function of accepting designation of a region to be a print object in the displayed image; a color material amount acquiring function of specifying a target representing a color equivalent to a color represented by the region among a plurality of targets, and acquiring an amount of the color material reproducing spectral reflectance characteristics equivalent to the target from a database; and a printing function of performing printing based on the amount of the acquired color material.

A color difference ΔE between a target color value expressed by color measurement data MD obtained by measuring colors of a target TG under plural light sources and an estimation color value obtained when a printer performs printing on the basis of an ink amount set φ is calculated for each of the light sources. When the color difference can be calculated for each of the light sources, an evaluation value E (φ) obtained by linear combination of the color differences is calculated. In addition, the ink amount set φ is calculated as an optimum solution for minimizing the evaluation value E (φ).

An image processing device generates output data used when an image displayed on a display device is to be output by an output device. The image processing device includes an output execution instruction input unit and a color space converter. The output execution instruction input unit inputs an instruction to execute image output via the output device. The color space converter carries out a first conversion process and a second conversion process. The first conversion process converts first device-dependent image data that expresses an image in a first device-dependent color space handled by the display device into device-independent image data that expresses the image in a device-independent color space. The second conversion process converts the device-independent image data into second device-dependent image data as the output data that expresses the image in a second device-dependent color space handled by the output device. The color space converter initiates the first conversion process prior to an input of an instruction to execute output by the output execution instruction input unit. The color space converter initiates the second conversion process in response to the input of an instruction to execute output by the output execution instruction unit.
