EVALUATION AND TEST OF A FIVE-COLOR ELECTROSTATIC PRINTING MACHINE FOR THE REPRODUCTION OF TOPOGRAPHIC MAPS AND CHARTS.
Abstract
The report covers the test and evaluation of an engineer-design, test-model, five-color, electrostatic printing machine for the reproduction of 22 1/2- by 30-inch topographic maps from 70-mm microfilm originals. The reproductions are on photoconductive paper utilizing liquid-immersion development. The report also treats the suitability of the machine design as a basis for the combined engineer test - service test models. This report evaluates the registration, image resolution, dimensional stability, continuous-tone possibilities, image quality, maximum-image size, speed, sheeting, and other capabilities of the machine and system for use in printing topographic maps. The report concludes that: The five-color, electrostatic printing machine utilizing 70-mm film chips and liquid immersion development has demonstrated a capability for reproducing acceptable, multicolor topographic maps for field use; The basic machine configuration of the five-color, electrostatic printing machine is sound; Various machine processing components need to be modified in order to increase the quality and accuracy of map reproduction.
