InDesign Guide: Bleed (3 mm) and Print-Ready PDF

When you add a 3 mm bleed and export the file correctly as a PDF, your print will be trimmed cleanly without unwanted white edges.

Quick idea: Bleed is an “extra edge” that won’t remain visible, but it ensures a clean trim. Text and logos should always stay inside the safe area.

1) New document: set bleed from the start

Path in InDesign

File → New → Document → Bleed

  • Set Bleed: 3 mm (Top/Bottom/Inside/Outside)
  • If the chain icon is active, one value is enough
  • Keep important content at least 4–6 mm away from the trim line

How do you see the bleed area?

  • The bleed is shown outside the page as a red line
  • Extend background colors and images up to (and beyond) the red line
  • Keep text and logos clearly inside the safe zone
InDesign: 3 mm bleed shown as a red line outside the page
The bleed appears in InDesign as a red boundary outside the page.

2) Existing document: add bleed afterwards

File → Document Setup → Bleed

  • Set 3 mm on all sides
  • Finally, check that backgrounds/images extend into the bleed area
Bleed can be added later via Document Setup.
Remember: Only background colors or images belong in the bleed area.
Do not place text, logos, or important elements inside the bleed.

3) Export a print-ready PDF (recommended)

File → Export → Adobe PDF (Print)

4) Quick check before sending

  • Open the PDF and confirm the bleed is visible (background continues past trim)
  • Make sure pages are separate (not spreads)
  • Zoom to 200–300% and check text/logos remain sharp

Tip: If your background reaches the edge, bleed is essentially required.
