SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This recipe automates the creation of complete book cover spreads (back, spine, and front) for print-on-demand publishing, ensuring correct spine calculation and layout at high resolution.

Core Features & Use Cases

  • Calculate spine width from page count and assemble back cover with ISBN barcode
  • Rotate and place the spine title, and attach the front cover image in a single API call at 300 DPI
  • Output is RGB (PNG, JPEG, or WebP); CMYK conversion for print-ready files can be done as a separate post-processing step

Quick Start

Provide the book metadata (title, author, page count) and a front cover image, then call the image-generation API with computed spine width and bleed to generate the spreads.

FAQPage Schema
How do I calculate book cover spine width for print-on-demand publishing?

To calculate book cover spine width for print-on-demand publishing, this skill uses your book's page count metadata to automatically compute the accurate spine dimension and assemble the complete print-ready spread.

How do I generate a complete print-ready book cover spread with an ISBN barcode?

You can generate a print-ready book cover spread by providing book metadata and a front cover image. The skill calls the image-generation API to assemble the back cover, ISBN barcode, and spine title at 300 DPI.

Does the book cover spread output support CMYK color mode for printing?

The book cover spread output generates high-resolution RGB files (PNG, JPEG, or WebP). CMYK conversion for print-ready files is not automatic and must be handled as a separate post-processing step.

What do I need to assemble a full book cover spread with spine orientation?

To assemble a full book cover spread, you need an Iteration Layer API key, book metadata (title, author, page count), and a front cover image to render accurate spine width and spine-title orientation.

Can I automate back cover, spine, and front cover assembly in a single API call?

Yes, you can automate back cover, spine, and front cover assembly in a single API call. The image-generation API calculates spine width, integrates the ISBN barcode, and rotates the spine title simultaneously.

What is the best way to create high-resolution book cover spreads at 300 DPI?

The best way to create high-resolution book cover spreads at 300 DPI is using an image-generation API that computes bleed dimensions and spine width, rendering the entire layout in formats like PNG or WebP.
