How Professional DTP Improves Machine Translation and AI Output

Machine Translation and AI-powered workflows are becoming standard across the translation industry. But even the best MT engines can only perform as well as the quality of the source file.

Poorly prepared documents — broken sentences, messy tags, compressed tables, scanned PDFs, or text embedded in images — lead to inaccurate MT output, more post-editing time, and frustrated teams.

At WLA DTP Services, we see this every day: when the file is properly prepared and professionally rebuilt, MT and AI deliver far better, cleaner, and more consistent translations.

This article explains how DTP impacts AI/MT quality and what steps agencies can take to optimize their workflow.

1. Pre-Translation File Preparation: The Step That Makes or Breaks MT Quality

A fast “DTP Pre-Check” before sending content to MT can dramatically improve translation results.

Below are the most critical steps:

a) Fixing broken sentences and inconsistent line breaks

MT engines struggle when:

• sentences are split across multiple lines,
• hard and soft returns are mixed,
• invisible spaces or corrupted characters exist.

Cleaning these issues results in clearer, more coherent MT output.

b) Tag cleaning and style normalization

Documents exported from PDFs or auto-generated files often contain:

• broken tags,
• duplicated tags,
• inconsistent paragraph/character styles,
• leftover formatting from previous workflows.

A basic tag cleanup helps MT engines process the text correctly and reduces layout issues after translation.

c) Rebuilding scanned documents with proper OCR

When working with scanned PDFs, the quality of the OCR makes a significant difference.

Professional DTP teams:

• apply high-accuracy OCR,
• rebuild tables,
• correct distorted characters,
• restore proper reading order.

A reconstructed file can improve MT accuracy by up to 40%.

d) Extracting text embedded in images

Text inside images, charts, or diagrams cannot be read by MT engines.

Extracting or redrawing these texts ensures full content coverage and prevents missing segments.

2. Post-Translation DTP: Turning Raw MT Output into a High-Quality Deliverable

After MT or AI generates the translation, the DTP phase ensures that the final file is visually accurate, readable, and ready for delivery.

a) Handling text expansion and contraction

Languages like German, French, and Arabic often expand considerably.
DTP adjustments include:

• resizing or repositioning text boxes,
• reorganizing elements,
• preventing widows, orphans, and layout breaks.

This step restores the original look and feel of the document.

b) Ensuring correct fonts, styles, and multilingual support

Raw MT output may introduce:

• inconsistent styles,
• broken fonts,
• unsupported characters,
• incorrect RTL directionality.

DTP ensures typographic integrity across all languages, including complex scripts.

c) Tables, forms, and interactive PDF components

This is one of the biggest challenges in MT workflows.

DTP professionals:

• rebuild tight or complex tables,
• preserve form functionality,
• maintain correct tagging and structure,
• ensure that the translated version looks and behaves exactly like the original.

3. Why MT + DTP = Better Quality, Faster Turnaround, Lower Costs

When agencies combine MT with proper DTP preparation, projects benefit from:

✔ Higher MT accuracy

✔ Fewer context errors

✔ Less post-editing time

✔ Reduced back-and-forth between PMs and linguists

✔ More professional, consistent final files

✔ Faster turnaround time

A 10-minute DTP source check can save hours in later corrections.
