There is certainly nothing in our library to help produce 
separations in the same way that Distiller or various
prepres tools do.  
Help me understand what you want a bit better. Are you hoping to 
read in an arbitrary bitmap, include it in a CMYK document, and then 
have Quark or some other tool separate the image layers in the
resulting PDF? Or something else?
