KDP Cover Wrap

Build print-ready paperback covers for Amazon KDP. Three surfaces: front, back, spine — plus the composited wrap. AI generates the artwork panels; Pillow handles the wrap geometry so nothing drifts.

When to use

• User wants a book cover or back cover for a print paperback.
• User wants the "full wrap" (back | spine | front) as one file for the KDP upload.
• User asks about spine width, bleed, or safe zones on a cover.

Mental model

Panels are art. The wrap is math. Never ask an image model to render the entire wrap in one shot — back-cover copy gets smudged, spine text hallucinates characters at <128 px wide, and centering drifts. Generate panels at 2:3 aspect, then composite.

Three phases:

1. Panel generation — front and back at 1024×1536 (or 1800×2700 for print) via GPT Image 2 high quality.
2. Wrap composition — Pillow script stitches back | spine | front with a spine generated locally (true typography, not AI-hallucinated text).
3. Template alignment — overlay the KDP template PNG to verify bleed, safe zones, spine position, barcode box.
