Inkers are artists who specialize in the process of inking illustrations, particularly in comic books and graphic novels. They take the pencil drawings created by pencil artists and enhance them by adding ink lines, which define shapes and details. This step is crucial as it prepares the artwork for printing and gives it a polished look. The inking process can involve various tools, such as brushes, pens, and markers, allowing for different styles and effects. Inkers work closely with writers and colorists to ensure that the final product aligns with the overall vision of the comic or graphic novel.
