A letterer is a member of a team of comic book creators responsible for drawing the comic book's text. The letterer's use of typefaces, calligraphy, letter size, and layout all contribute to the impact of the comic-book-reading experience. The letterer crafts the comic's "display lettering": the story's title lettering, creator credits, and any specialized captions that appear on the story's first page. They also craft the lettering that appears in the word balloons, also designing the various sound effects that appear within the comic book story. Many letterers also design logos for the comic book company's various titles. Source: Wikipedia (en)
