Abstract
A method for varying colors of a picture image, displayed in a color display, for reproducing a color printed matter, in which density signals of cyan, magenta, yellow and black, picked up from an original picture are fed to a color display to display a color picture image corresponding to the color printed matter to be obtained is disclosed. Color ink signals of cyan, magenta and yellow for recording a color printed matter are converted into color separation density signals of red, green and blue by using the first table memories, and then the converted color separation density signals are added one by one. Then, correction values for printing the color inks one above another, read out of the second table memories depending on the color ink signals, are added to the added color separation density signals. A correction value for printing the black ink upon the other color inks, read out of the third table memory depending on the black and the color ink signals, may be added to thus the obtained signal.
