The quality of machine translation with full post-editing should correspond to the quality of a human translation. This means that, just as with human translation, full PE ensures that the translation is correct in terms of spelling, grammar, terminology, formatting, etc. The post-editor also ensures consistency and an appropriate style. The main difference to human translation is that the style does not have to be perfect.
However, machine translations with full post-editing are not ISO 17100-compliant and do not comply with VDE specifications either. So if you need a certified translation, we recommend a human translation including revision according to ISO 17100.
