<p>An image processing system for colour reversing, in which code data is received from a host computer via a reception buffer and analyzed. A logical operation is performed between bit patterns developed in bit-map RAM areas corresponding Y (yellow), M (magenta) and C (cyan) inks or toners and a bit pattern developed in a bit-map RAM area corresponding to a K (black) ink or toner, the K bit pattern is cleared, and the bit patterns of the Y, M and C bit-map areas that have been subjected to the logical operation are reversed, whereby an attractive color reversal is realized. <IMAGE></p> |
