Monotype is the name given to a special printing technique, in which only one copy can be printed. Instead of printing on paper or canvas, the classic monotype is painted on glass, acrylic or metal plates. While the paint is still wet, it is printed directly onto paper.

So the monotype allows only this one full print. Further impressions are possible, but these are always lighter due to the loss of color.

The monotype was invented in the 17th century by Giovanni Benedetto Castiglione and belongs to the fine arts. Various other artists have used this process, but not in the form Patrizio did.

He has improved it and lifts with the repeated on such an absorbent surface as needle felt,

he stands out from other artists.
