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 method and apparatus for producing a color conversion profile for use in a color inkjet printer, a color laser printer, or the like. In one embodiment, a spectral printing model converter is used to sample ink amount data to spectral reflectance Rsmp(λ). Using this spectral reflectance Rsmp(λ), colorimetric values CV1, CV2 under two different viewing conditions are calculated, and an evaluation index EI that includes an index of color difference between the colorimetric values CV1, CV2 is calculated. I another embodiment, an evaluation index EI that includes an index of color difference between sample color represented by sample ink amount data and reference color obtained from a reference color patch is calculated. Sample ink amount data having the best evaluation index EI is then selected as a representative sample. Profiles are created from the plurality of selected representative samples.
