摘要： A spectral printing model converter is used to convert ink amount data to spectral reflectance of a color patch to be printed according to the ink amount data. A plurality of sample ink amount data each representing a set of ink amounts of plural inks is provided, and each sample ink amount data is converted into spectral reflectance of a virtual sample patch to be printed with the ink amounts represented by the sample ink amount data using the spectral printing model converter. An evaluation index is calculated for each sample ink amount data, where the evaluation index includes a color difference index and an image quality index of the virtual sample patch to be printed according to the sample ink amount data. The color difference index represents a color difference between a sample color which is calculated from the spectral reflectance and a comparative color which is selected as a basis for comparison. Plural sample ink amount data is then selected based on the evaluation index, and a profile defining correspondence between calorimetric value data and ink amount data is produced based on the selected plural sample ink amount data.

摘要： In one example, there is designed a system for calculating an evaluation index for sample ink amount data from a color difference evaluation index and an image quality evaluation index, and creating a profile based on a highly rated sample. In this system, the printer driver is designed to use different indexes to create plural profiles, and to perform color conversion using these plural profiles. These plural profiles may be selected appropriately according to user needs, printing conditions, type of image targeted for printing, and the like.

摘要： A profile is created for making correspondence between a lattice point in an ink color space composed of ink colors and a lattice point in a device-independent color space by: defining a virtual force acting on a focused lattice point in a device-independent color space and obtaining the focused lattice position in a stable state reached when the virtual force acts on the focused lattice point; and working based on a transform model for transforming a lattice point in the ink color space into a lattice point in the device-independent color space to obtain a lattice point in an ink color space corresponding to a focused lattice position in the stable state and creating the profile by making correspondence between both.

摘要： In order to create a profile that associates lattice points defined in an equipment-dependent color space with lattice points defined in an equipment-independent color space, a reference profile that associates a plurality of lattice points in the equipment-dependent color space with lattice points in the equipment-independent color space is retrieved. A virtual force that acts on a focused lattice point in the equipment-independent color space is defined, and a position at which the focused lattice point is located in a steady-state in which the virtual force acts on the focused lattice point is calculated. The reference profile is referenced in order to retrieve a lattice point in the equipment-dependent color space associated with the position of the steady-state focused lattice point. A profile is created by associating the position of each steady-state focused lattice point with a lattice point in the equipment-dependent color space.

摘要： A method for determining lattice points to be referenced to prepare the correspondence defining data, said method including steps of prescribing a smoothness evaluation function which has a function form differing depending on each region in the color gamut to which the lattice point to be evaluated belongs and also contains a constraint condition that the closer the lattice point is to the boundary of the region of the color gamut, the more the evaluated value decreases as the result of its movement, optimizing the arrangement of lattice points in the device-independent color space by improving the rating of the smoothness evaluation function, with the lattice point position information in the low-dimensional color space varied, and determining lattice points to be referenced to prepare the correspondence defining data in the optimized state.
