KDP Coloring Book Interior Preparation
Best fit: KDP coloring books where each finished artwork page exists as an image file and the author needs a consistent 300 DPI paperback interior PDF.
Common problems
- Artwork pages are different pixel sizes.
- KDP reports insufficient bleed or unexpected white edges.
- Backing pages need to be inserted after every coloring page.
- The PDF page order changes because filenames are not sorted cleanly.
How Book Interior Kit helps
The app imports the artwork folder, sorts the files, places each image on a KDP-style page canvas, optionally adds gray-black backing pages, and previews the PDF locally before export.
Still required before publishing
Review the final PDF in KDP Previewer. Book Interior Kit reduces preparation mistakes, but it cannot guarantee KDP approval and is not affiliated with Amazon or Kindle Direct Publishing.
