what you download
One ZIP per book. Upload two files.
- interior.pdfA title page, a “this book belongs to” page, then every design on its own right-hand page. Its back is blank except a small strip for testing colors, so markers do not bleed through onto the next picture.
- cover.pdfBack, spine and front on one page with 0.125 in bleed. The front shows two of the book’s own designs colored in (or the first one as drawn, if you choose); the back shows a page as it is inside.
- check-report.pdfOur check of both files against KDP’s paperback specs, signed. Anyone can confirm it is genuine on the verify page.
- listing.txtTitle, subtitle, description, seven keyword ideas, the print options to pick and the facts for KDP’s AI question.
- preview/Six images of real pages for your listing, A+ content or posts.
- README.txtThe upload steps, the rights note and the report id.
Every image here is a page of one of the two sample books, shown as delivered. Farm Friends was made from the theme “friendly farm animals and life on the farm” in 131 seconds; all 11 designs passed on the first drawing. Before a design goes into a book it passes two checks: our pixel check (closed shapes, no gray, the right amount of ink) and a separate judge that scores the lines, the outlines, the subject and the print. A design that fails is drawn again, at our cost.

$0.25 a design, or $0.165 in the big pack.
A 20-design book is 500 credits, the same as one puzzle book: $5.00 in the small pack, $3.30 in the big one. The cover, the file check and every redrawing are in the price.
the guarantee
If a book cannot be finished, it is not charged: the credits go back to your key by themselves. If KDP rejects a book’s files within 30 days of making it, write to data@voiddo.com with the report id and KDP’s message, and the book’s credits go back too. Unused credits can be refunded within 14 days of purchase.

Questions
Do I answer “yes” to KDP’s AI-generated content question?
For the images, yes. Every picture inside is drawn by an AI image model from a short description, then cleaned, traced and checked by ordinary computer programs. The colored pictures on the front are two of those designs colored in by the same model, then enlarged for print; listing.txt names every tool used for each book. With a theme, the descriptions are written by an AI writing tool; with your own list, they are yours. listing.txt states these facts so you can answer KDP’s questions from its own definitions. The choice and the responsibility are yours as the publisher.
Can I sell the book? Are the pictures mine alone?
You may publish and sell the book under your own name. In the US, pictures made by AI alone are generally not protected by copyright, so we cannot promise that nobody else will publish similar pictures. Every book is drawn fresh: the same theme asked twice makes two different books.
What if a picture comes out wrong?
It does not go into the book. Each design must pass our pixel check and the judge; a failed one is drawn again at our cost. With a theme, a picture that keeps failing is swapped for one of the spare ideas. With your own list, a picture that keeps failing is drawn simpler; if it still fails, the book stops, says which picture, and every credit goes back.
What can’t I ask for?
Characters and brands that belong to someone else, such as Disney, Pokémon, Bluey or Minecraft. KDP removes books that use them, so the form refuses them before anything is charged.
How long does it take?
About 2 minutes for 11 designs and up to 20 minutes for 50, longer if other books are ahead in the queue. You can close the page: the book keeps going, and when you come back on this browser it appears under your recent books. Finished files are kept for 14 days.
Do I need an ISBN?
No. KDP gives a free ISBN to paperbacks, and coloring books are not treated as low-content books, so the free ISBN is available. listing.txt says which options to pick.
Can I use the API instead of this page?
Yes: POST https://data.voiddo.com/v1/kdp_coloring_book with the same fields as JSON and your key in the Authorization header. It answers at once with a job id; ask GET /v1/jobs/{id} for the progress and GET /v1/jobs/{id}/download for the ZIP. See the API docs.
