Abstract : The Standard Printing Screen (SPS) System adopted by the Department of Defense for its Mapping, Charting, and Geodesy (DOD-MC+G) agencies, is described. It establishes a system of dot screens with visual tones of equidistant increments as viewed by an average observer. The system includes the full range of tints, from paper white (0% tone) to solid color (100% tone). The report includes the standardization of dot, bi-angle, line pattern and area pattern screens. It also describes the creation of a 100-step continuous growth halftone scale for the purpose of specifying quality control tolerances of screen tints for the printed product. (Author)
