Abstract
In some cases, an image that has undergone color conversion in correspondence with the output characteristics of a printing press as a target is printed using a copying machine or printer for the purpose of proof. Prior to such proof, an output device profile is generated. In this case, it is desired to easily confirm and tune the generated profile. According to this invention, tuning images to be proofed and chart images before and after color conversion are parallelly displayed as independent windows. An arbitrary color range to be tuned is selected on one of these windows, a tuning parameter is set for the selected color range, and a color conversion condition is tuned based on the tuning parameter.
