You have received an input file that requires trapping throughout. Instead of individually trapping each item, you want to trap all elements when the file is refined into PDF pages. Trap width standards are specific to your shop and need to be implemented as part of the trapping process.

Refine PDF pages again to set trap information

  3. In the Start Process dialog box, click the Edit Process Template button.
  4. Open the Trap section in the process template.
  5. Change the Trap Size: Width/Height setting to 0.5 pt. (.175 mm).
  6. Click OK.
    Note: The setting of 0.5 pt. (.175 mm) is being used only for demonstration purposes. This will provide a trap line that is easily viewed. For your own purposes, set the trap value as defined by your shop standards.

    Note: Editing this process template is temporary. When you modify a process template in this way, any changes to the process template are discarded when the process is complete. The changes do not affect the original process template and are not saved with the job. You cannot redo the same process without making the same changes to the process template again.
