A sign designer is a graphic design specialist who creates the visual elements of a sign, such as a billboard, window display, or advertisement. Your duties and responsibilities in this career are to consult with art directors and other creative designers in your department to understand what kind of sign your client wants. This may include specifications such as color scheme, appropriate brand logos, and other visual elements that fit in with the campaign or goals. You then design a layout for the clients to review. If it meets their approval, you enter production and ensure that you have taken care of all physical components.
