Check and fix bleed

pdfToolbox 11 introduces a new Process Plan for identifying and fixing bleed issues. Limitation: It will only work with PDF files where all pages have the same size.

This Process Plan is based on many years prepress experience and has been developed by calibrate (office@calibrate.at). All JavaScripts in the Process Plan are protected and cannot be displayed.

When you start the Process Plan you are asked for:

  • Safety zone distance from TrimBox
  • Required bleed
  • Bleed tolerance
  • Unit
  • Create required bleed (mirroring)
  • Page type (single or facing)

The first three input fields are illustrated by this diagram.

During processing pages are analyzed on all four edges. A page edge is classified as requiring bleed if

  • there are objects in the "safety zone distance from TrimBox"
    AND
  • the required bleed zone is empty or the required bleed zone is not empty but at the edge of the tolerance there are no objects

The respective page edge is then either reported or - if "Create required bleed" is selected - bleed is added via mirroring page content.

The method to add bleed can be adjusted in the Process Plan.
