Pipeline steps

1 Generate line art

Prompt for high-contrast black line art on white, single subject, no gray fills, consistent stroke weight. Generate extras for picks.

Best tool: Midjourney

Tip: Avoid photorealism; ask for ‘coloring book page, thick clean outlines, no shading’.

2 Clean & edit

Remove artifacts, close gaps, erase stray marks, convert to pure B/W.

Best tool: Adobe Photoshop

  • Photopea — Free browser alternative for threshold/cleanup
  • Canva — Quick background cleanup for simple pages

Tip: Flatten layers; remove transparency before PDF.

3 Upscale if needed

If line art is soft under 300 DPI at trim size, upscale before layout.

Best tool: Topaz Gigapixel

  • Adobe Photoshop — Preserve Details 2.0 / Super Resolution as alternative

Tip: Upscale first, then threshold again so lines stay crisp.

4 Layout interior

Place one page per PDF page at chosen trim (e.g. 8.5×11). Add page numbers if desired. Keep art inside safe margins unless using bleed.

Best tool: Affinity Publisher

  • Canva — Faster for short books with fixed page templates
  • Book Bolt — KDP-oriented interior templates

Tip: Match KDP trim exactly; don’t enlarge images after insert.

5 Cover & mockup

Build wrap cover from KDP cover calculator dimensions; mockup for A+ / ads separately.

Best tool: Canva

Tip: Flatten cover to one 300 DPI image.

6 Export & upload

Export print-ready PDF interior + cover; upload to KDP; order a proof.

Best tool: Canva

Tip: Proof copy before wide release.

7 Disclose & list

In KDP publishing flow, disclose AI-generated images (and text if any). Publish paperback.

Best tool: Canva

Tip: AI-assisted-only edits of your own art may not need disclosure — generated pages do.
