ABSTRACT:
A method for image regulation of a color monitor in proof-viewing and an apparatus therefor which is characterized in that the image on the color monitor is caused to closely resemble the printed picture, and said method comprises the steps of: scanning separation films of primary colors to obtain primary color picture signals; obtaining secondary color picture signals from the NAM (Non-Additively Mixing) portions which are derived by detecting the maximum value of two of said primary color picture signals respectively; while obtaining a tertiary color picture signal from the NAM portion of said primary color picture signals; regulating said secondary and tertiary color picture signals by multiplying regulation factors; correcting the gradation of said primary color picture signals by said regulated secondary and tertiary color picture signals; and producing an image on a color monitor screen with said corrected primary color picture signals.
