Trap a PDF

Trapping is a complex process that depends on the interaction of various color, ink, and printing factors; the correct settings vary, depending on specific press conditions. Do not change the default trap settings unless you’ve consulted with your print service provider.

  1. If necessary, choose Advanced > Print Production > Trap Presets to create a trap preset with custom settings for your document and printing press conditions.
  2. Assign the trap preset to a page range.
  3. Choose File > Print to open the Print dialog box, and then click Advanced.
  4. Select Output from the list on the left.
  5. For Color, choose In-RIP Separations.
  6. For Trapping, choose Adobe In-RIP.
    Note: This option works only when you target an output device that supports Adobe In-RIP Trapping.
  7. Click Ink Manager. As necessary, select an ink, specify the following options (only if your service provider recommends changing the settings), and then click OK:
    Option Description

    Neutral Density

    Type a value that differs from the default.

    Trapping Sequence
