A new feature in PDF 1.3 was the ability
to define a document that has information beyond its final trim
size. In the graphic industry, this information usually includes
bleed, registration marks and other print and color control strips.
Using the View Page Boxestool , you can easily preview the
information outside of the final trim size of your document.
This information is defined in the application that was used to create the original PDF file, for example, Adobe InDesign or Quark XPress. Once they are made visible using PitStop Pro, these elements can be edited, added, or removed, just like any other graphic object.
Some PDF documents are generated without
any bleed, registration marks or other print and color strips. When
you click the View Page
Boxes button for these documents, the page
will appear the same (except for a thin trim line drawn at the edges
of the image).
You can manually move and edit the page boxes in your document, using
the Edit Page Boxes tool
