How were maps produced?
Manuscript Maps
 
Printed Maps
Maps were printed in Europe for the first time in the second half of the fifteenth century. Indeed the first map was printed within a generation of the development of movable type by Johannes Gutenberg. This map is a TO map and is found in a copy of Isidore of Seville's encyclopedia, printed in 1472 by Günter Zainer in Augsburg, Germany.
Two forms of printing, woodcut and copper engraving (intaglio) were used to produce the first printed maps. The woodcut is the older printing technique and comes from China. The oldest example of a printed map is from the ninth century and shows one of the provinces of China. The method of printing from a copper engraving was developed at the beginning of the fifteenth century in Europe and was first used to print a map in 1477.
Woodcut
The woodcut is a raised surface printing technique. A cherry or pear board, cut along the grain, is used. After the map is transferred in mirror image to the board, the blank area of the map is cut away to a depth of about 1/8 to 1/4 of an inch using variously shaped knives and gouges. Only the image is left in the form of ridges. To print from the woodcut the raised surface is inked using a roller and then a sheet of paper is pressed onto the inked surface of the woodcut in a printing press.

 

Copper engraving
Copper engraving is an Intaglio printing method. The map image is, similar to the woodcut, transferred in mirror image to a polished copper plate. Unlike in the woodcut the lines of the map are engraved into the plate using burins with different profiles, leaving the blank area untouched. To print, the surface of the copper plate is rubbed with ink so that the engraved lines are filled with it. The surface is then cleaned leaving only the ink in the engraved lines. The plate is then run through a roller press with a piece of dampened paper, transferring the ink to the paper.
 
Copper etching
The Copper etching is, like the copper engraving, an Intaglio printing method. The lines though are etched, not engraved into the plate. For map printing copper etching is almost exclusively used only for decorating the map with pictures, such as the title cartouche. The printing process is the same as for the copper engraving.
