ABSTRACT:
An image processing system includes a color reversing capability, and code data is received from a host computer via a reception buffer and analyzed. It the data includes a color reversing instruction, a logical operation is performed between bit patterns developed in bit-map RAM areas corresponding to yellow (Y), magenta (M) and cyan (C) inks or toners, and a bit pattern developed in a bit-map area corresponding to a black (K) 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, resulting in an attractive color reversal.
