The right level of review
Formal correction, stylistic editing or comparison with the original: we agree the right review before work begins.
Spelling, grammar, punctuation and formal presentation.
Wording, style, specialist terminology and targeted text improvement.
Completeness and correct display in the print layout or digital product.
Language quality assurance
Our editors are native speakers of the language being reviewed. We select them by text type, subject and requirements. You specify whether the work covers formal correction, style or editorial changes to content.
For multilingual publication, we recommend a coordinated sequence: improve and proofread the source text, review the translation against the original, then check the finished language layouts or digital applications.
The scope in detail
We distinguish monolingual correction, editorial work, bilingual revision and final approval checks.
We review the source text for spelling, grammar and syntax. This includes punctuation and correct presentation of hyphenation, indentation, units, figures and lists.
This stage focuses on formal accuracy. More extensive changes to style or content require the corresponding editing or text optimisation scope.
Editing reviews formal and content accuracy. We also improve wording and expression, and check specialist terms for suitability and consistency where required.
The aim is a coherent, fluent and engaging text in the agreed style.
We improve German and foreign-language texts to your requirements for clarity, expression and style. Unlike purely stylistic editing, this can include changes to content.
Sentences can be rewritten and sections shortened, expanded or reorganised. We can summarise texts on request. The text’s purpose and intended audience guide the work.
We compare the translation with the source sentence by sentence, checking that the content and intention have been conveyed appropriately and precisely.
We review the typeset text for completeness, correct line breaks and hyphenation, and implementation of the source and other layout requirements.
Layout proofing is a separate final review after text editing and typesetting. It prepares the final version for print approval.
Testing is the corresponding final review for software, online training, websites and audiovisual media. We check completeness and correct display in the target environment.
Where text cannot be edited directly, we record corrections screen by screen in a separate script, so changes can be implemented in the product.
Ambiguities and errors in the source can multiply during multilingual production. Pre-editing reviews and prepares content before further processing, improving the basis for every language version.
This includes editorial improvements, clarity and consistent terminology, adaptation to cultural or market-specific requirements, and technical preparation of formatting and encoding.
Well-prepared texts can reduce later corrections and post-editing, speed up production and save time and cost. The benefit depends on the source material and workflow.
In post-editing, language specialists review and correct software-translated content. The review level, intended use and quality target are agreed beforehand; terminology and the source text remain the basis.
For voice recordings, we prepare production-ready scripts. Transcription with the necessary timecodes, translation of texts for spoken delivery and subtitles in the agreed languages and formats can be ordered separately or within a multilingual media production.
