METHOD AND APPARATUS FOR LIMITING INK GROSS VOLUME, INK GROSS VOLUME LIMIT DISPLAY COLOR CONVERTING METHOD, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To prevent cockling in the case of printing in ink based on a plurality of halftone image data displayed by multi-values by a processing the data. SOLUTION: Multi-valued data C, M, Y, K of densities of one pixel of noted pixel are read from a recording medium (S100), overall ink density ND is calculated (S110), and whether it is larger than a predetermined limit value L1 or not is judged. If it is not larger than the value L1 (NO in S120), original multi- valued data of the noted pixel are binarized as they are. If it is larger than the value L1 (YES in S120), an ink density reducing calculation for reducing the multi-valued data of the respective colors is conducted (S130), and it is binarized based on the obtained reduced multi-valued data C3, M3, Y3 and the multi-valued data K of black (S140).
