You can't guarantee an overall even result because of the firing process for the glaze, also the manufacturers are probably trying to counteract grout seepage rather than encourage it. Try using a runny consistency of black grout on a spare tile: if you can't get the effect you're looking for I'd advise you to give up or you'll end up replacing all the tiling work because it will look awful. Good luck.
