METHOD AND DEVICE FOR DETERMINING SEPARATED FOUR PRIMARY COLOR QUANTITIES, INFORMATION RECORDING MEDIUM, AND PROGRAM FOR DETERMINING SEPARATED FOUR PRIMARY COLOR QUANTITIES

摘要

PPROBLEM TO BE SOLVED: To provide a method and a device for determining separated four primary color quantities originally as undecided problems with practically sufficient precision, and a computer-readable information recording medium where the determination program is recorded. PSOLUTION: Provided is the method, etc., for determining the separated four primary colors comprises the steps of: obtaining a target color stimulation value, etc.; calculating optical density from the target color stimulation value, etc.; obtaining four primary color stimulation values, etc.; calculating optical density from the four primary color stimulation values, etc.; obtaining a black addition rate; calculating density values of the respective four primary colors for reproducing a color reproduction target color; and calculating separated four primary color amount for reproducing the color reproduction target color.
