High Quality Content by WIKIPEDIA articles! The inker (also sometimes credited as the finisher, embellisher, or tracer) is one of the two line artists in a traditional comic book or graphic novel. After a pencilled drawing (or copy of the pencilled drawing) is given to the inker, the inker uses black ink (usually India ink) to produce refined outlines over the pencil lines. The ink may be applied with a pen or a brush — many inkers use both — or even digitally, a process gaining in popularity. The inker is usually responsible for every black line on the page, except for letters, which are handled by a letterer. In many comic strips, as well as Japanese manga and European comics, a single artist takes responsibility for penciling, inking and sometimes even lettering, either doing it all (e.g., Charles M. Schulz) or hiring assistants. For comics printed in color, there is usually a separate colorist.
