What is the meaning of 'finer'?

Hello everyone,
I’m reading artofmanliness.com/2009/05/06/so … ranslator/ , in which I am having a question.

Translation and interpretation are two completely separate jobs. Translation involves the written word and strict attention must be paid to the finer linguistic details. Interpretation deals with the spoken word and as such is a much more fluid and dynamic art. You don’t have time to reach for a dictionary when communication breaks down.

What is the meaning of ‘finer’? Does it mean ‘accurate’ in this case? What is it comparing to?

Thanks.

the higher order (more complex) details that characterise high quality linguistic ability.

finer = higher quality
