Manage trap presets
You can duplicate, delete, import, and customize trap presets.
Duplicate a trap preset
❖ Do one of the following:
• In the Trap Presets panel, select a preset and choose Duplicate Preset in the panel menu.
• Drag a preset to the New Preset button at the bottom of the panel.
Delete a trap preset
1 In the Trap Presets panel, select the preset(s), and then do one of the following:
• Click the Delete button.
• Choose Delete Presets in the panel menu.
2 If prompted to replace a trap preset, choose one in the Delete Trap Preset dialog box that appears. This dialog box
appears if at least one of the selected presets has been assigned to a page.
3 Click Yes to confirm the deletion.
Note: You cannot delete either of the two built-in presets: [Default] and [No Trap Preset].
Import presets from another InDesign document
1 In the Trap Presets panel, choose Load Trap Presets in the panel menu.
2 Select the InDesign file and click Open.
Assign a trap preset to pages
You can assign a trap preset to a document or to a range of pages in a document. Pages with no abutting colors will
print faster if you disable trapping on those pages. Trapping doesn’t actually occur until you print the document.
