- A print-ready PDF needs no further edits before printing.
- It has the correct trim size and required bleed.
- All fonts are embedded and images are high-resolution.
- Color is set correctly (often CMYK for covers).
- Each printer publishes its own specifications.
A print-ready PDF is a file prepared to a printer's exact specifications so it can be printed with no further changes. That means the correct trim size, the required bleed and margins, all fonts embedded, images at sufficient resolution (usually 300 DPI), and the right color setup (CMYK for covers; grayscale or as specified for interiors). Self-publishers create separate print-ready PDFs for the interior and the cover, following the provider's template and guidelines, then verify each before uploading.
Chapter i·Why it matters
Submitting a file that is not print-ready causes rejected uploads, delayed launches, and printed books with errors — wrong margins, blurry images, missing fonts, or off color. Understanding what "print-ready" requires helps authors prepare or commission files that pass provider checks and print correctly the first time. Knowing the components (trim, bleed, fonts, resolution, color) lets authors review their files or a designer's work confidently, protecting both their budget and their launch timeline.
Chapter ii·What to include
- Correct trim size and bleed.
- Embedded fonts.
- High-resolution images (typically 300 DPI).
- Correct color setup (CMYK for covers).
- Separate interior and cover files.
- A check against the provider's spec sheet.
Chapter iii·Example
A self-publisher prepares two PDFs to her print provider's template: an interior at the right trim with embedded fonts and 300-DPI images, and a CMYK cover with proper bleed. She checks each against the provider's spec sheet before uploading. Because both are print-ready, the files pass review and print without errors.
