ABSTRACT:
A color separation method for converting plural kinds of picture signals obtained by photoelectrically scanning an original color picture with a color separation optical system into reproducible picture image signals by a plurality of kinds of color inks in which the first color separation signals types of black print of which are full-black or close thereto are converted into the second color separation signals, deflection amount between the first and the second color separation signal is obtained according to which said second color separation signals are corrected into third color separation signals. A picture basing on the third color separation signals is compared with that of basing on the first color separation signals on a color monitor and according to the result of comparison the picture image basing on the third color separation signals is visually approximated or coincide with the first one by adjusting the correction amount of said color separation signals.
