How blueprint prints on KDP
- A full blue background prints as heavy ink on every page: use it on premium color and keep text in panels or on the facing page. Its black-and-white version is black technical lines on white.
- In color it prints on white paper: KDP's standard color uses 50–61 lb (74–90 GSM) paper and premium color 60–71 lb (88–105 GSM). KDP recommends premium color for image-heavy books such as children's books and cookbooks.
- On black-and-white interiors, KDP asks for printed lines of at least 0.75 pt and recommends gray fills of at least 10%.
- KDP needs images at 300 DPI or more at print size; every illustration is prepared at that resolution.
Compare what each interior costs with the printing cost calculator, and read how to choose the trim size and paper.
Same characters, every page
Before the pages are painted, each main character gets a reference sheet in this style. Every illustration is drawn with those sheets as references, so faces, clothes and colors stay the same from the cover to the last page. Text is never painted into the art: titles, captions and dialogue are typeset on top.
Prompt tips for blueprint
- Inventions, rockets, robots and vehicles are natural subjects.
- Ask for front, side and exploded views to show how something is built.
- Measurements are never drawn in; add them as text on the page if you need them.
