In my Master Page spread I'm adding a shadow effect to look like the center of a magazine, but the default border lines are messing me up.  Really it's only the center/border line.  It's showing as a lighter line over the shadows I've added.  Of course it's does not export so everything comes out fine.  But when adjusting the shadow and blur effects it's hard to determine exactly what I got until export. So, how can I hide this? Any ideas please.
