rgb to cmyk conversion problems

[bobby18301]

I have a typical rgb job from a client. He has some boxes and type in a standard Publisher blue. When I convert the job to CMYK all the blue items turn to almost solid black. I had to go through the whole job and manually re-color all these items.

Does anyone have a clue as to why this would happen?

One more reason why Publisher is still a most exasperating program.
