Caution: The way traps are displayed depends on the screen resolution and on the zoom factor currently set. To judge the traps on the screen, you must first zoom up the section of the page you want to view. If you do not set a high enough scale factor, it is possible that only some of the traps will be displayed.
Caution: Viewing the traps in Acrobat can be misleading in certain cases if the Acrobat Overprint Preview is not enabled.
Caution: Make sure that the page you wish to edit has no unwanted spot colors.
Note: You cannot trap preseparated and pseudo-composite pages.
The following items must always be remembered when working with PDF Toolbox:
•You should not subsequently change the contents of a page that is already trapped. However, if you have to change them, you should delete all the traps beforehand using the Trap Editor. After you make your changes, you must then trap again if required.
•While the PDF Toolbox is being used, in Acrobat you should only use functions affecting the view mode and no other functions.
•Only when the PDF document is saved with Acrobat are the changes made with PDF Toolbox permanently saved.
•Wherever possible, the overprint feature is used when traps are created.
