Annie, regardless if it is all around or only once, if you print full frame showing the brush strokes the ident mark will show. Frankly I hope they dont do this since most of the time 11x14 are to be used for contact printing, seems kind of silly of them to ruin a print by having the ident mark on the edge of the film, but then that is Kodak for you, left hand does not know what the right one is doing.

If they do this foolishness and the ident mark is only one then you might be able to bleach it out. Of course if it is all around then this would be really hard work, I would suggest then that you mask the edge and show the print without brush strokes.
