Standards for medical graphics

A lack of understanding of simple standards is responsible for poor quality graphics in slides, overhead projection transparencies, posters and publications. The ready availability of computer graphics application programs has led to a proliferation of well-executed, but poorly constructed illustrations. Guidelines are given for the design of scientific illustrations, with reference to correct labelling, line weights, font styles and sizes, the use of colour, and other factors affecting the clarity of presentation. The application of established standards for the preparation of medical graphics as described is strongly recommended.
