EVALUATION AND TEST OF A FIVE-COLOR ELECTROSTATIC PRINTING MACHINE FOR THE REPRODUCTION OF TOPOGRAPHIC MAPS AND CHARTS

摘要

This report covers the test and evaluation of an engineer-design, test-model, five-color, electrostatic printing machine for the reproduction of 22 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.
