Adjacent objects with a gap
 

Just wondering if this is something that can't be helped.

In this picture, the rectangles above have a stroke. The ones below aren't stroked. When printed and Preview'd, the ones without a stroke show a gap. In OmniGraffle, I can zoom in 800% and there's no gap.

Just wondering if this some limitation that just has to be worked with.
