There are a few ways in which artists or illustrators and book designers can work together in the context of communication design. A friend of mine who works in publishing regularly commissions and art directs illustrators to fulfil her vision for book jackets. Here, the role of both is quite clear and fixed. The book designer provides conceptual direction and even design samples and hints. Speaking generally, it is the designer that is the driving force of the work. The illustrator ‘envisions’ the designer’s concept using a particular illustration style and media.
