摘要： Systems and methods for establishing ink usage of process channels are provided. Separation curves are generated that determine how multiple ink channels are used to render a corresponding process channel of an image. The separation curves are generated using process values and density measurements or estimations. A PVR curve is established to identify target densities. When a combination of ink channels are used, the model is accessed based on one of the ink channels to determine a contribution of the other ink channel to achieve the target density. Each ink channel has a corresponding curve and all of the curves collectively provide a smooth and predictable progression from zero coverage to full coverage for the ink channels.

摘要： An image processing apparatus in the present disclosure includes a color conversion processing unit, a modulation candidate creating unit, a color value modulating unit, and an output unit. The color conversion processing unit performs color conversion from an input color value of a target image to a corresponding output color value to obtain a tentative output color value. The modulation candidate creating unit creates, as modulation candidates, combinations of integer values obtained by rounding up or down the decimal fraction of each color component of a tentative output color value. The color value modulating unit selects a modulation candidate at random and performs modulation by replacing the tentative output color value with the selected modulation candidate. The output unit outputs the target image according to the color value obtained after the modulation.

摘要： A method controls the coloring of a printing press. In the method a test element is printed with a number of colored measuring areas. The printed colored measuring areas of the test element are then measured. Actual colorimetric values are calculated from the measured color values and then displayed. Reference colorimetric values are entered and adapted spectral color values are calculated. Densitometric, colorimetric, or spectral actual tonal values or actual tonal value gains are determined from the calculated actual colorimetric values of a subset of the colored areas of the test element. The densitometric, colorimetric or spectral reference tonal values or the reference tonal value gains are entered and adapted spectral color values are calculated by a comparison with the calculated actual colorimetric values. The adapted spectral color values for the calculation of color profiles, process calibrations and process control values are stored and the printing press is activated.

摘要： An image processing apparatus includes a plurality of color conversion tables for color-separation-limited printing. Using a color conversion table for color-separation-limited printing, a piece of input color information corresponding to chromatic color within a specified applying hue range for a specified specific color is converted into a piece of output color information corresponding to color having hue of the specific color, and a piece of the input color information corresponding to color outside of the applying hue range is converted into a piece of the output color information corresponding to gray color. Each of the color conversion tables for color-separation-limited printing is configured such that color values corresponding to saturation and lightness of the output color information are reduced at least in gradation from a maximum saturation part to a low-lightness part.
