"Preparing print layouts for IngramSpark requires setting interior margins and bleeds to keep text from wrapping into page folds."
Core Key Takeaways
- Calculating Gutter Margins for Page Counts
- Preparing Bleed Margins for Full-Bleed Pages
- Exporting PDF Files for Printing
1. Calculating Gutter Margins for Page Counts
Gutter margins protect text from binding folds. As page counts increase, gutter width must expand to compensate for binding depth.
- For books under 150 pages: Set a 0.375-inch gutter margin.
- For books with 150 to 300 pages: Set a 0.5-inch gutter margin.
- Maintain outer margins of at least 0.5 inches to protect text.
2. Preparing Bleed Margins for Full-Bleed Pages
If illustrations stretch to the page edge, add a 0.125-inch bleed margin on all outer edges to prevent white lines after cutting.
3. Exporting PDF Files for Printing
Export interior files as single-page PDFs (not spreads) using PDF/X-1a formats to ensure compatibility with print-on-demand machines.
