Patent ID: 8665494

Claim:
A printing control apparatus that causes a second printing apparatus to execute printing based on reference image data which is image data printed previously by a first printing apparatus, in a state where the first printing apparatus and the second printing apparatus are identical to each other in a number of colors of used ink, are different from each other in at least one color ink, and are different from each other in a color conversion table for converting an input gradation value of a device-dependent color space depending on a printing apparatus into an output gradation value of a device-dependent color space in which an ink color is a color component, the printing control apparatus comprising: an output characteristic receiving unit that receives a selection indicating whether or not reference output characteristics, which are output characteristics of a color of the first printing apparatus, are reproduced by the second printing apparatus; a profile specifying unit that sets a first profile, said first profile regulates a relationship between the input gradation value of the device-dependent color space depending on the first printing apparatus and a gradation value of a device-independent color space, as an input profile, and sets a second profile, said second profile regulates a relationship between the gradation value of the device-independent color space and the input gradation value of the device-dependent color space depending on the second printing apparatus, as an output profile, when the selection reproducing the reference output characteristics by the second printing apparatus is received; a color converting unit that specifies colors for each pixel of a case, where gradation values for each pixel shown by the reference image data are input gradation values of the device-dependent color space depending on the first printing apparatus, by the input gradation value of the device-dependent color space depending on the second printing apparatus, based on the input profile and the output profile, and specifies the output gradation value by converting a specified input gradation value based on a color conversion table of the second printing apparatus; and a printing execution unit that causes the second printing apparatus to execute the printing based on the specified output gradation value.
