APPARATUS AND METHOD FOR PLATE CONDITION DISPLAY PROGRAM FOR DISPLAYING PLATE CONDITION AND INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a proofreading system in which a desired spot color can be expressed more correctly and recognized and the efficiency of the proofreading operation can be improved, compared with a case where a platemaking operator visually makes a plate corresponding to the spot color.

SOLUTION: Color decomposition information Ssp corresponding to each of four primary colors is generated on the basis of PS data Srps corresponding to the four primary colors for printing. Color decomposition information Ssp corresponding to PS data Srps digital spot color other than the four primary colors is generated on the basis of this spot color. Color image information Srgb indicating the state of each plate corresponding to the four primary colors and the spot color is generated on the basis of dot data Smx each corresponding to the four primary colors and the spot color and each item of the color decomposition information Ssp. The generated information is displayed on a display 121.
