Graphic design is the process of visual communication, and problem-solving through the correct use of typography, space, image and color. The field is considered a subset of visual communication and communication design, but sometimes the term “graphic design” is used interchangeably with these due to overlapping skills involved. Graphic designers use various methods to create and combine words, symbols, and images to create a visual representation of ideas and messages. A graphic designer may use a combination of typography, visual arts, and page layout techniques to produce a final result. Graphic design often refers to both the process (designing) by which the communication is created and the products (designs) which are generated. Common uses of graphic design include identity (logos and branding), publications (magazines, newspapers, and books), print advertisements, posters, billboards, website graphics and elements, signs and product packaging. For example, a product package might include a logo or other artwork, organized text and pure design elements such as images, shapes, and color which unify the piece.
