Matt or Ed...where are you? :-)

I can give you Matt's advice for him: don't use Publisher's CMYK; work in RGB and separate to CMYK in Pitstop.

My understanding of CMYK is far from encyclopaedic, but I'd guess that Publisher is separating the black in the image to 100 100 100 100 (overprinted). "True" black is unachievable in print; even the blackest material discovered still reflects some light, so black ink is far from "true" black. Obviously adding more and more ink will make things darker, so overprinting 100 black with 100 CMY will give a darker black than 100 black on its own.

(As an aside, try this: Imagine a white wall. If I asked you its colour, you'd obviously say "white". Now, imagine that the wall has a digital projector pointed at it, projecting a PowerPoint slide that is entirely white apart from a black square in the middle. If I asked you what colour the square was, you'd say "black". But the square is formed by an absence of illumination from the projector, so is exactly the same colour as the wall - which is white! Of course the kind of people who go round using data projectors all the time are the same kind of people as routinely turn white into black anyway :D)
