Preparation and Presentation of Low-Cost Projectable Materials
This paper introduces the subject with a historical treatment that relates the requirements for low-cost projectable materials to the evolution of the “overhead projector.” It describes engineering efforts and design which have given this medium certain advantages of versatility. It further projects engineering goals for overcoming existing limitations. Low-cost projectable types are exemplified with reference to styles of presentation and methods of production.
