What is the difference between etching and engraving, or between aquatint and 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 numerous illustrations, this book defines and explains the techniques, processes and materials used in 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. The inclusion of more colour images, modern printmaking techniques and other new developments in the field make this the up-to-date, concise reference book on the subject.
