Image edges bleeding to next page when exporting

Question

Wondering if anyone can help me?
I've created a newsletter in Indesign and have placed images and coloured boxes to the edges of some of my pages. But when I export the newsletter to PDF the image edges are showing up on the adjacent page (even though they are only on one page in Indesign). How can I stop this?

>Should one add bleeds so that the imposer would be able to pull everything toward the edge of the page without leaving an unprinted strip in the gutter??
John, there are two ways of keeping the outer margins uniform while making the creep adjustment:
1. The inner pages of the signature are progressively moved toward the spine, with the inner margins becoming progressively smaller. This method needs no extra bleed image beyond the inside page edge.
2. The outer pages of the signature are progressively moved away from the spine, with the inner margins becoming progressively larger. This method does indeed need the source pages to have extra bleed image beyond the inside page edge.
High end imposition software have the flexibility to do it either way depending on the specific needs of the case at hand, and this is selectable by the pre press operator using the imposition software. Some times even a combination of the two methods can be used in the same signature so that half of the pages are shifted outwards, while half are shifted inwards.
So pages that are going to have an outward creep adjustment may need to be handled as Peter outlined in #6.
Peter please note from this example that spiral bound books are not the only case where bleed needs to be provided at the spine. In fact all signature work needs this consideration if a creep adjustment of the second kind is to be used. But lets keep it in perspective: this is a very fine point in imposition work and can generally be ignored.
