ABSTRACT:
A color image-forming machine comprises a color image signal-forming means for outputting digital signals Cd, Md and Yd expressing, on tone levels, three primary colors C, M and Y for each of a number of pixels, and a correction means for correcting the digital signals Cd, Md and Yd by using a correction table. The correction table is formed by forming masking operation correction tables using many masking operation expressions, and then, detecting singular portions in the masking operation correction tables, and modifying the detected singular portions.
