Translators are people, too . And people have limits. So it’s not reasonable to demand a translation agency or translators to complete more than five translation pages (1,800 characters per page) a day. Most translation agencies also charge and additional fee for a speedier translation – usually as much as 30–50%. In principle, 15 pages per day is a limit in case of which adequate quality can still be achieved. It would be ideal to know such needs in advance – that way we can plan people and technical aids. But don’t request this too often .
Of extreme examples, translating 200 pages in a week is a good one. This, however, requires cooperation between translators, harmonising terms, an excellent project manager, editor and a coincidence of many good things. And to be honest, you cannot expect to get the best translation in such circumstances.
All in all: plan things in advance (easy to say, right ), give us enough time and you’ll get a much better translation if we don’t rush.
