If your system is fully licensed for trap editing, you can switch back and forth between PDF Trap Viewer and PDF Trap Editor. You don't have to close the software or the PDF file being reviewed first.
Perform one of the following actions:
- On the Acrobat Kodak Tools toolbar, click the PDF Trap Viewer
button or the PDF Trap Editor 
button. - In Acrobat versions 8 or 9, select Advanced > Kodak Tools > Kodak PDF Trap Editor, or Kodak PDF Trap Viewer.
Note: If you have items selected, you will lose the selection list while the trapping software re-analyzes the page. - In Acrobat X, select View > Tools > Plug-In Kodak Tools and then select the Kodak PDF Trap Editor icon from the Tools panel on the right.
