How to Use Split-Page Background Images

A split-page background spans one image across both pages of the opening spread. Lacuna splits the image down the center and puts each half on its page, and the section always starts on the right-hand (recto) page so readers see the whole spread at once. For a single-page background, see background images.

Print only

Split-page backgrounds appear only in your print-ready PDF. They are ignored in EPUB.

Add a Split-Page Background Image

1. Open the section’s Options menu
2. Choose Set Section’s Background, then Set Print Background Images
3. Switch to the Split Page tab and click Upload Split Background Image (or Browse Existing Images)

There is no separate switch to turn on: uploading an image on the Split Page tab activates the spread. Use a wide landscape image, and keep the focal point away from the center so it reads well once the image is split across two pages.

Image Settings

• Bleed. Safe Zone keeps the image inside the printable margins; Full Bleed runs it to the trimmed edges across the whole spread.
• Fill. How the image scales: Fit, Cover, or Fill.
• Position. Anchor the image to the Top, Center, or Bottom of the spread.
• Opacity. Lower it to soften the image so text stays readable across both pages.
