what is your exact problem? What have you tried?

You need to define more precisely what the target CMYK output is, as this is one of those conversions that does not have a simple answer (see http://en.wikipedia.org/wiki/CMYK#Conversion). Once you have defined the CMYK target completely, you will find that you have solved the problem.
