    Abstract: An information processing apparatus includes a processor configured to, in a case where a first color material, a second color material, a third color material, and a fourth color material in which a difference between the first color material and the fourth color material in a color space is less than a threshold value, are capable of being used, output combinations of values of color materials reproducing a first color, which is used for expanding a color gamut of a secondary color of the first color material and the second color material, and a second color, which is used for expanding a color gamut of a secondary color of the first color material and the third color material.

    Abstract: According to exemplary methods, a processor of a printing device determines color values out of a first colorant combination using marking materials for standard colorants and marking materials for one or more extended gamut colors. The extended gamut color has colorants other than the standard colorants. Responsive to the first colorant combination including color values for each of a pair of two complementary colors, the processor calculates a second colorant combination that produces the same human-perceivable color as the first colorant combination. The second colorant combination includes only one color of the pair of two complementary colors. The printing device produces output using the second colorant combination for the standard colorants and the extended gamut color.

    Abstract: In a method to control a color printer or color copier, a color separation of a first color and a color separation of a second color are applied to a printing substrate to generate a print image. Also, with aid of a printing unit, at least a first control field is printed on the printing substrate. The first control field has a predetermined pattern that includes at least the first color and the second color and is designed such that a color value of the first control field changes depending on a registration error between the first and the second color separations. A reference field is also printed on the printing substrate, a pattern of the reference field being predetermined such that it has a same color value independent of the registration error. The color value of the first control field is measured with a color value sensor. The color value of the reference field is also measured with the color value sensor and a desired color value is determined depending on the color value of the reference field. A deviation between the measured color value of the first control field and the desired color value is determined, the deviation corresponding to a spatial shift of the color separations. At least one control signal is generated to reduce the spatial shift depending on the determined deviation.

    Abstract: The present disclosure advantageously provides apparatus, systems and methods which facilitate estimating and accounting for illumination conditions, viewing conditions and reflectance characteristics for imaged surfaces when performing color measurement, correction and/or transformation in an imaging process, such as photography. Advantageously, the disclosed apparatus, systems and methods may utilize a set of one or more illumination target elements for extrapolating illumination conditions from an imaged scene. The disclosure may be used to improve determination of color correction/transformation parameters and/or to facilitate determining a reflectance model for a target surface of interest.
