the simplest method is: R = 255 - C; G = 255 - M; B = 255 - Y; ignore K. Of course, the resulting RGB colors might not be axact; there are
It depends on the pcr setting used by the separator, but this will probably give rather washed-out dark areas. Try subtracting K from each of RGB as well, ie. R = (255 - C) - K;... etc, for a slightly better result. And clip against zero.
