Service introduction

About our kdp & print-ready book formatting service

Print-on-demand platforms reject files that don't match their trim, bleed and margin rules.

We set up your files to your chosen platform's published requirements and check margins, bleed, fonts and image resolution before handing over.

Platform requirements

Files built to Amazon KDP and IngramSpark specification

KDP and IngramSpark have different bleed rules, different spine calculations and different minimum margins, and a file built for one will often be rejected by the other.

We build to whichever platform you are using, calculating the spine from your final page count and paper type rather than estimating it. The interior PDF is preflighted, the cover wrap is sized from the platform's own template, and the ebook is supplied as a validated EPUB with a working table of contents. If you are publishing to both, we supply both file sets.

  • Spine calculated from final page count and paper choice
  • Validated EPUB with functioning navigation and TOC
  • Separate file sets for KDP and IngramSpark where needed

This service is mainly used by KDP and IngramSpark authors in the United States, United Kingdom, Australia, Canada, the UAE and India. Send us your project details and we will reply with questions, an approach and a quote before any work starts.
