What is the difference between etching and engraving, or between aquatint or mezzotint? What is bodycolour? And what exactly does it mean to say a work is 'ascribed' or 'attributed' to an artist? With the aid of generous illustrations, this essential reference guide defines and explains the techniques, processes and materials used in works of art on paper. Updated and expanded to include many more colour pictures as well as new entries on digital printmaking, copies, reproductions and fakes and a new appendix on the care of works of art on paper, it will be invaluable not only to all those wishing to increase their understanding and enjoyment of prints, drawings and watercolours, but also to anyone who is thinking of starting a collection.
