    Abstract: A profile adjustment method includes: accepting first input profile as a first component, accepting at least one of a second input profile and a spot color as a second component combined with the output profile, accepting a first target of adjustment values when color conversion is executed according to the first component and the output profile, accepting a second target of adjustment values when color conversion is executed according to the second component and the output profile, and adjusting the output profile based on the first and second targets. A first output profile may be accepted as the first component combined with the input profile and a second output profile may be accepted as the second component combined with the input profile.

    Abstract: An image processing method comprising: converting an RGB input signal to a CMYK signal; converting the RGB input signal to a common color signal including lightness; generating a first Gray signal including a Gray value substituted for CMY values forming gray in the CMYK signal; generating a second Gray signal including a Gray value corresponding to a K value greater than a threshold in the CMYK signal; generating a Gray output signal in a CMYKGray output signal indicating color material amounts of cyan (C), magenta (M), yellow (Y), black (K), and gray (Gray) for printing by multiplying the generated first Gray signal and the generated second Gray signal respectively by coefficients corresponding to the lightness in the common color signal and then synthesizing the first Gray signal and the second Gray signal.

    Abstract: A method for converting color data includes reading from a memory the color data represented in a first color space; converting the color data into un-premultiplied color data; converting the un-premultiplied color data from the first color space to a second color space; converting the un-premultiplied color data in the second color space into first premultiplied color data; and writing the first premultiplied color data to the memory.

    Abstract: In an image processing apparatus, an area separating unit classifies a property of a pixel in an image into any of plural properties that include at least a character property and an image property, a black generation and UCR processing unit performs a black generation process and a UCR process for the image, and a process amount specifying unit specifies a black generation amount and a UCR amount used in the black generation process and the UCR process to the black generation and UCR processing unit. Further, the process amount specifying unit sets the black generation amount and the UCR amount on the basis of a smallest color component value of a pixel with the image property using a conversion characteristic that varies in accordance with a lightness value, a chroma saturation value and a hue value of the pixel with the image property.

    Abstract: Provided is a color conversion table creation method for creating a color conversion table for an image forming apparatus which forms an image by performing, on an input color value with total use amount of color material exceeding set amount, a process for reducing the total use amount of color material, the table presenting correspondence between the input color value input to the image forming apparatus and an output color value in a device-independent color space. The method includes: acquiring an input color value of a patch image for creating the table; when the total use amount of color material defined by the acquired input color value is around the set amount, adjusting the input color value to have a smaller difference between the total use amount and the set amount; and creating the color conversion table using the patch image with the adjusted input color value.
