Abstract:
An information processing device includes: an image acquirer that acquires an image to print onto a medium; a color converter that converts color in the image acquired by the image acquirer depending on a positional relationship between a white image forming section that forms an image on the medium with white color material and a color image forming section that forms an image on the medium with colored color material; and an image output unit that outputs the image whose color is converted by the color converter.
Abstract:
A correcting apparatus includes a first acquiring unit that acquires a target characteristic expressing a correspondence relationship between a gradation value and a target density of an image to be output from an output apparatus in accordance with the gradation value; a second acquiring unit that acquires an output characteristic expressing a correspondence relationship between a gradation value and a measured density of the image output from the output apparatus in accordance with the gradation value; an updating unit that updates the target characteristic by correcting the target density corresponding to a high density region including a maximum target density value when a difference between a maximum measured density value and the maximum target density value is larger than a predetermined value; and a correcting unit that corrects the gradation value so as to approximate the output characteristic to the updated target characteristic.
Abstract:
An image processing apparatus includes a first converter and a second converter. The first converter converts coloring-material amounts of plural coloring materials including a luster coloring material to plural colorimetric values obtained in a case of performing, in plural color measurement directions, a color measurement of a target color image printed using the plural coloring materials. The second converter converts the plural colorimetric values obtained as a result of conversion by the first converter to display values for displaying the target color image on a display device.
Abstract:
An image forming apparatus includes an image forming unit and a controller. The image forming unit forms an image on each medium with a metallic toner. The controller controls the image forming unit such that, in the formation of an image on each medium of plural media different in reflectance, the metallic toner has a toner weight according to the medium.
Abstract:
An image processing device includes an accepting unit, and a conversion information generating unit. The accepting unit accepts items of read data in a device-dependent color space that are generated by reading color patches, items of reference data in a device-independent color space of the color patches, and items of specific color component data each indicating a specific color component in a corresponding one of the color patches. The conversion information generating unit generates conversion information reflecting the presence or amount of a specific color component included in each color patch as information for converting input data in the device-dependent color space to output data in the device-independent color space, on the basis of the items of read data, the items of reference data, and the items of specific color component data.
Abstract:
An image processing apparatus includes a calculation unit and a white layer density determination unit. The calculation unit calculates, based on multiple color component signals to be used for image formation, an image layer halftone percentage of an image layer to be formed on a recording medium. The white layer density determination unit determines, based on the image layer halftone percentage, a white layer halftone percentage of a white layer to be formed as an underlying layer of the image layer on the recording medium.

Abstract:
A color processing apparatus includes a first subtracting unit, a second subtracting unit, and an output unit. The first subtracting unit subtracts color values of CMY color signals corresponding to an achromatic color value from color values of input CMY color signals in accordance with replacement to the achromatic color value. The second subtracting unit subtracts color values of CMY color signals corresponding to a color value of an additional color signal different from the CMY color signals from the color values of the CMY color signals after the subtraction by the first subtracting unit in accordance with replacement to the color value of the additional color signal. The output unit multiplies the color values of the CMY color signals after the subtraction by the second subtracting unit and the color value of the additional color signal by N (N>1) and subsequently outputs the color signals,
Abstract:
A color conversion device includes a receiving unit receiving colorimetric values obtained by measuring plural target-color images of different tones from plural directions; a memory storing a color conversion model associating a combination of colorimetric direction and color material amounts of respective colors and actually measured color values; and a converter converting the colorimetric values into color values including values indicative of amounts of glittering color material and other color materials, wherein the converter calculates, for each target-color image, a weighted average of color differences between colorimetric values of the target-color image in colorimetric directions and color values in the colorimetric directions obtained from the model by using preset weighting coefficients and selects a combination of weighting coefficients that makes tone characteristics closest to tone characteristics of the target-color images by changing the weighting coefficients when a combination of color material amounts minimizing the weighted average is determined.
Abstract:
An image forming apparatus includes an image forming component that forms an image on a recording medium by using a white color material and a color material other than the white color material, and a controller that controls a color material amount of the white color material to differ depending on a position where an image that uses the white color material is formed in order of formation of images that use respective color materials in the image forming component.
