ELECTRONIC SCANNING FOR COLOR SEPARATION OF THEMATIC MAPS

THE U. S. GEOLOGICAL SURVEY IS DEVELOPING CARTOGRAPHIC AND LITHOGRAPHIC TECHNIQUES FOR COLOR SEPARATING THEMATIC MAPS BY ELECTRONIC SCANNING. TO DATE, THREE USGS GEOLOGIC MAPS HAVE BEEN COLOR SEPARATED BY ELECTRONIC SCANNING AT THE U. S. ARMY TOPOGRAPHIC COMMAND AND AWAIT PUBLICATION. SAVINGS RESULTING FROM PRODUCING THEMATIC MAPS FROM HAND-COLORED ORIGINALS ARE ESTIMATED AT 30 PERCENT IN COST AND 50 PERCENT IN CALENDAR TIME. A REPRINT PROGRAM USING ELECTRONIC SCANNING FOR COLOR SEPARATION OF PUBLISHED MAPS WILL ALSO SAVE COSTS AND CALENDAR TIME BY ELIMINATING HANDLING OF MAP MATERIALS AS WELL AS REDUCING THE NUMBER OF PRESS RUNS AND PRINTING COLORS. /AUTHOR/
