Qualifications and memberships
Independent DTP work built around translation workflows
Most DTP work in the multilingual space sits in a gap: it requires both deep layout knowledge and an understanding of how translation processes work. Translators are not layout specialists. Designers are not familiar with CAT tools or IDML structure. Clients end up needing someone who bridges both sides.
That is where DTP Services Berlin operates. The focus is on production-ready output: documents that come out of translation in the right format, with correct typography, no overset text, proper RTL handling, and accessibility tagging to PDF/UA-1 where required.
Translation agencies managing multilingual document projects, publishers working across language markets, and international organisations that need accessible PDF output.
Core services and specialisations
Layout preparation and post-translation typesetting across European, Middle Eastern and Asian languages, including complex scripts and character encoding.
Remediation to PDF/UA-1 and WCAG 2.1 AA: tags, reading order, alt text, heading structure, document language and form field labels, validated with PAC 2026 and tested with NVDA.
Arabic and Hebrew typesetting in InDesign with the World-Ready Paragraph Composer: mirrored layouts, correct paragraph direction and mixed LTR/RTL text.
File preparation for CAT tool processing, IDML export and re-import, post-translation cleanup and final production hand-off for agency project pipelines.
Tools used in production
How a typical project runs
-
File assessment
Every project starts with a review of the source files: InDesign package, PDF, or both. This surfaces font issues, missing links, IDML compatibility problems, and any accessibility requirements before work begins.
-
Preparation for translation
Files are prepared in a format suitable for the translator's CAT tool: clean IDML export, paragraph style cleanup, hidden layer removal, and any text expansion space allocation for target languages known to run longer.
-
Post-translation typesetting
Translated content is re-imported and the layout is corrected: overset text resolved, hyphenation adjusted for the target language, fonts confirmed or replaced, and right-to-left settings applied where required.
-
Final output and delivery
Output is either a print-ready PDF, an accessible tagged PDF (PDF/UA), or a packaged InDesign file, depending on the project. Accessible PDFs come with a remediation report for the client.
Based in Berlin, Germany. Working remotely with clients across Europe and internationally. All communication and file exchange is handled digitally, so location does not limit the project.
How client files are handled
A client NDA is signed before any files are shared.
Files are handled on a single work computer, with a backup on an external drive for the duration of the project. If a client requires it, files stay on this computer only, with no cloud sync.
Files are deleted as required by law, and at any time when the client asks.
Whether a project uses AI-assisted work or none at all follows the assignment. Instructions given with the order are followed.
Writing on multilingual production
Alongside client work, this site publishes articles on the topics that come up most often in multilingual DTP projects: translation file handling, text expansion, InDesign setup for complex scripts, PDF accessibility, and related production workflows.
The articles are written for project managers and translation agencies who commission this kind of work. They show what is involved and what to watch for.
