A penciller (or penciler) is an artist who works on the creation of comic books, graphic novels, and similar visual art forms, with a focus on the initial pencil illustrations, usually in collaboration with other artists, who provide inks, colors and lettering in the book, under the supervision of an editor. In the American comic book industry, the penciller is the first step in rendering the story in visual form, and may require several steps of feedback with the writer. These artists are concerned with layout (positions and vantages on scenes) to showcase steps in the plot.
