Focusing on the production and utilization of printing processes in constructing effective visuals for teaching, this bulletin contains articles on the silk screening stencil process, use of a similar process with a portable mimeograph, and the hectograph process. The first article lists equipment needed to make a silk screen, steps in building the printing outfit, three methods for constructing stencils, recipes for film adherent liquid and water soluble adherent liquid, directions for paint application, screen cleaning procedures, and drying of finished silk screen prints, including instructions for building a drying rack. The second article illustrates use of the portable hand-operated mimeograph, and the third describes a hectograph and gives instructions for its construction and use. The final article briefly describes more expensive processes, i.e., typeset, intaglio, planography (offset), electrostatography (xerography), and diazo. (JB)
