How to design (multiples)… Multiples are designed with the methods of research. Unlike the artist, the designer does not make a wonderful sketch and later find some reproduction technique. He experiments on a phenomenon which is optical, physical, geometrical, typological, mechanical… He refines the elements of communication, and studies the best material with which to produce the object for the maximum level of visual communication and the minimum level of cost. He finds the mechanical technique which best suits his purposes, and in the end a prototype is born—not a unique artistic creation, but a model for the creation of a series. Reproductions of artwork are always inferior to the original, but when designing a model for mass production, the prototype is always inferior to the final products.
