Most likely cause, if I understand your question correctly, is that the surface of the mold is not totally smooth. The reason for that is that the original master was not smooth. To get a super slick, smooth finish on your master you can use a thin coat of epoxy, lacquer or similar.
Another option is to dip your "semi-gloss" part in hot, thin clear Alumisol which will create a slick surface.
Good question.
