I want to know the answer to the following question:
What does an inker do?
All the background I'm provided with is that "Particularly in American superhero comic books, the art may be divided between a penciller, who lays out the artwork in pencil; an inker, who finishes the artwork in ink; a colourist; and a letterer, who adds the captions and speech balloons.". Is that enough to answer the question?
