Expression value of printmaking is equivalent to other techniques in visual art.
Etching, aquatint and dry needle were invented in the 16th century due to the need for faster distribution of information. Techniques were slowly forgoten by invention of litography until in the early 20th century. Picasso brought them back to life as new medium for his expression which was followed by other modernists. Traditional printmaking techniques are interested also in contemporary art because of their processual work.
