ABSTRACT:
A scanner set-up simulation unit is connected to a color scanner which comprises a reading head for reading an image information of the color original wound on a reading drum and for producing color separation signals, a first gradation correction circuit for correcting a gradation of the color separation signals, and an exposure head for exposing color separation films wound on a recording drum based on the corrected color separation signals output from the first gradation correcting circuit. The simulation unit comprises a level adjusting circuit for adjusting the white and black levels of the color separation signals, an IC memory for storing the color separation signals from the level adjusting circuit, a second gradation correction circuit for correcting a gradation of the color separation signals read out from the IC memory, and a color display for simulating and displaying a printed reproduction based on the corrected color separation signals from the second correcting means. After the gradation correction is ended, the corrected color separation signals from the second correcting means are supplied to the exposure head of the color scanner.
