look in the panel view, there is a small check box like 2 lines down from top on left under the panel size group that has little red arrows and a square. that tells PM to place a imaginary border around an object. suppose you are running 10 of those little cut jobs and want to put .5" in between them to ease your weeding and trimming, that box if you put .25 in (because it would be .25 from each side yielding .5 in between 2) you would have a half inch of play room between images or cut images. Can be helpful when maximizing numbers of decals per width of substrate.
