The processes of producing multiple copies of maps or map drawings. Reproductions are obtained by a number of procedures, including inked-plate printing, photographic processes, office copying equipment, and computers. Choosing a process depends on the use of the map, quality and quantity desired, cost, and availability of equipment. The reproduction process governs the techniques and media for preparing the original artwork. Some processes serve as intermediate stages in map reproduction. Finished reproductions can be on any material, but film and paper are most commonly used and are single color or multicolor.
