DTP Formats: Word (.docx) vs. PowerPoint (.pptx)
In global localization practice, two formats are most commonly used for OCR and desktop publishing of graphic files or PDFs: Microsoft Word (.docx) and Microsoft PowerPoint (.pptx). Whenever needed, documents can be exported from either into any other target format.
Despite sharing a similar internal architecture (both formats are technically ZIP archives containing XML markup), there is a fundamental difference between them:
- PowerPoint is strictly bound to fixed slides: every element is placed inside an independent frame with explicit coordinates.
- Word is inherently flow-based: it has no physically fixed pages, and text continuously reflows across the document depending on text volume and font settings.
Two Core Approaches to Layout Preparation:
1. Flow-Based Text with Core Formatting (Recommended)
Complex layout blocks are reconstructed using standard paragraphs or tables with hidden borders.
- Pros: during translation, text expands or contracts freely without breaking the layout structure. The document requires virtually no complex manual post-translation adjustments.
- Best suited for: legal documents, notarized translations, court filings, and submissions to official authorities.
2. Frame-Based Layout (Text Boxes)
Every text fragment is placed inside an individual text frame at the exact coordinates where it appeared in the source document.
- Pros: achieves maximum "1-to-1" visual fidelity to the original source layout.
- Cons: when translating into languages with high text expansion, sentences may overflow the frame boundaries (overset text), requiring manual frame resizing or font scaling.
- Best suited for: advertising brochures, presentations, and marketing catalogs.
