Prepare a KDP PDF in Affinity Publisher

Prepare print dimensions, facing pages, bleed and PDF output in Affinity Publisher.

What this issue means

Affinity export presets still require the correct document geometry and page selection. A post-export scan catches stray objects and box differences that the canvas view can hide.

What BookPreflight checks

  • Document units, trim and bleed
  • Master-page margins and spread behavior
  • Rasterization, font and PDF compatibility settings

How to correct the source file

  1. 1

    Set document dimensions before placing final artwork.

  2. 2

    Review all master pages and stray objects.

  3. 3

    Export the intended pages and verify the PDF independently.

Verify the exported PDF, not the preset name

Keep the editable source and original PDF. Export a new file, run the complete scan again and review every remaining finding. A repair is only labelled safe after loss checks and a full deterministic post-flight.
