Backdrop
Upload a PDF or image file using the file upload area in the Backdrop File section. The file is inserted underneath existing page content (the opposite of Overlay, which goes on top). Common uses include pre-printed stationery, textured paper backgrounds, watermark templates, or brand frames. The backdrop is composited at the specified scale and position on each targeted page.

Options Guide
Backdrop File
Upload the PDF to be placed behind page content.
Upload a single-page PDF containing your background artwork. If the backdrop is multi-page, page 1 is used. For best results, the backdrop should match or exceed the target page dimensions. If "Repeat" is enabled, the same backdrop appears on every page in the range; otherwise it appears only on page 1.
Settings
Control placement, size, and transparency of the backdrop layer.
Repeat: applies the backdrop to all pages in the range (ideal for stationery). Offset X/Y: shifts the backdrop from its default position in PDF points (1pt = 1/72in). Scale: enlarges or reduces the backdrop relative to its native size:100% = original. Opacity: controls transparency:100% is fully opaque, lower values let the page content show through the backdrop.
Pages
Specify which pages to process using a range expression.
Examples: 'all' = every page. '1-5' = pages 1 through 5. '1,3,5' = specific pages. '1-10 odd' = odd pages 1-9. '2-20 even' = even pages 2-20. 'last' = last page. 'last-2' = third from last. Ranges are 1-based. Combine with commas: '1-5, 8, 12-15'.
Configurations & Variations
Backdrop Applied
Click the file upload area in the Backdrop section to load a background PDF or image. The backdrop is placed behind your imposed content on every output page. Common uses: textured paper simulation, branded background, or a pre-printed shell layout. Set opacity to 100% for production shells and 10-20% for subtle textures. The backdrop file must match or exceed the output sheet dimensions; undersized backdrops leave white edges.

Expert Tip
Backdrop places a full-bleed background (texture, solid fill, or repeating pattern) behind your imposed content. Upload a PDF or image file as the backdrop. Faster than editing every source page individually when you need a uniform background across the job.
A backdrop with transparency or live effects can dramatically increase RIP time. Flatten the backdrop PDF first if your RIP is struggling.
