Abstract:
1. A print control system comprising: a color reference generation unit configured to generate color reference information defining a color reference for reproducing a color characteristic of a first output device by a second output device designated as a print destination using a first output profile representing a color reproduction characteristic of the first output device serving as a reference of color matching, wherein the color reference generation unit generates the color reference information based on PCS data of a profile connection space (PCS) corresponding to a device-independent color space in a case of outputting general-purpose RGB data of a general-purpose RGB color space corresponding to a color space on an input side of the color reference by the first output device; a first color conversion unit configured to apply color conversion to image data designated as a print target using the color reference information and a second output profile representing a color reproduction characteristic of the second output device; a transmission unit configured to transmit the converted image data to the second output device, and to request printing; a lattice point data generation unit configured to generate lattice point data of a color space; and a second color conversion unit configured to perform color conversion on the generated lattice point data using a profile representing a color reproduction characteristic of the color space; wherein the lattice point data generation unit generates the lattice point data of the general-purpose RGB color space; wherein the second color conversion unit determines the PCS data in a case of outputting the general-purpose RGB data with respect to the lattice point data by the first output device using an input profile representing a color reproduction characteristic of the general-purpose RGB color space and the first output profile of the first output device; wherein the color reference generation unit generates the color reference information based on the determined PCS data; and wherein the second color conversion unit replaces the general-purpose RGB values of a lattice point determined to be a black point among the lattice point data with the PCS values corresponding to the black point of the input profile, and performs black point correction.
