Why PDF Export Settings Matter
Creating a PDF from Scribus is more than clicking "Export." The settings you choose determine whether your file is suitable for professional printing, digital distribution, or web viewing. A PDF for a commercial printer requires entirely different settings than a PDF for screen reading. Getting this wrong can result in rejected files, color shifts, or missing fonts.
Accessing the PDF Export Dialog
Go to File → Export → Save as PDF. The PDF export dialog is extensive — don't be intimidated. It's organized into tabs: General, Fonts, Extras, Viewer, Security, Color, and Pre-Press.
Choosing the Right PDF Version
The PDF version you select depends on your output goal:
| PDF Version | Best For |
|---|---|
| PDF 1.4 | General printing, broad compatibility |
| PDF 1.5 | Layered documents, modern printers |
| PDF/X-1a | High-end commercial print (CMYK only) |
| PDF/X-3 | Commercial print with ICC color profiles |
| PDF/X-4 | Modern print workflows, transparency support |
For most professional print jobs, PDF/X-1a or PDF/X-3 are the standard requests from print service providers. Always ask your printer which version they prefer.
Font Embedding
Under the Fonts tab, ensure all fonts are embedded. Scribus lists fonts used in your document. You should:
- Embed all fonts by moving them to the "Fonts to Embed" list.
- Or convert fonts to outlines (curves) — this guarantees appearance but removes editability.
Important: Some fonts have licensing restrictions that prohibit embedding. Check your font licenses, particularly for commercial fonts.
Understanding Color Management in Scribus
Color management ensures that colors appear consistently across different devices — monitors, printers, and projectors all interpret color differently. Scribus uses ICC profiles and the LittleCMS color engine to manage this.
To enable color management:
- Go to File → Document Setup → Color Management.
- Enable the Activate Color Management checkbox.
- Assign color profiles:
- RGB Images: Typically sRGB IEC61966-2.1 for screen-sourced images.
- CMYK Images: Use the profile supplied by your print provider (e.g., ISO Coated v2).
- Printer: Set to your target output profile (the print provider's profile).
- Choose a rendering intent — for most print work, Relative Colorimetric with Black Point Compensation is recommended.
CMYK vs. RGB: Which Should You Use?
This is one of the most common questions for new Scribus users:
- CMYK: Required for professional offset and digital printing. Colors are defined as percentages of Cyan, Magenta, Yellow, and Black ink.
- RGB: Used for screen/web output and some digital printers that convert internally.
In Scribus, you can define colors as CMYK or RGB in Edit → Colors. For print work, define spot colors and process colors in CMYK from the start to avoid unexpected color shifts during conversion.
Pre-Press Settings: Bleed and Marks
Under the Pre-Press tab:
- Bleed: If your document has elements that extend to the page edge, you need bleed (typically 3mm). Ensure your document's bleed settings match here.
- Crop Marks: Enable these so the printer knows where to cut the paper.
- Registration Marks: Used by printers for aligning CMYK plates.
- Color Bars: Optional but useful for the print shop to verify ink density.
Preflight Checker
Before exporting, run Scribus's built-in preflight check via File → Preflight Verifier. It checks for common issues like missing images, RGB colors in a CMYK document, overset text frames, and low-resolution images. Resolve all errors before exporting your final PDF.
Summary
Scribus's PDF export and color management tools are comprehensive and professional-grade. Taking the time to understand ICC profiles, PDF standards, font embedding, and bleed settings ensures your documents are accepted by print service providers and look exactly as intended — both on screen and in print.
