When I had this problem a long time ago it was because the files were set up by the client. I told him he had to give me CMYK files, but, of course, he was working in RGB all the time.
Results All the grays were in the 3 colors, Such as: 10% gray was actually 6% Cyan, Mag & Yellow. If your printing set is perfectly balanced you may get away with it, But if it is not, or you push one color or the other colors it will tone. In my case, the client thought there was too much blue in his blues so we backed off the cyan and all of a sudden all his gray boxes turned magenta/pink. The other way it can happen is if you have the inks switched (because you were doing something with a special setup)
