Proof made from a defaced stone, plate, block or screen, to show that no further prints can be made from the original work of art.

a print pulled by the artist after the plate from which the edition has been printed has been defaced to ensure that no additional prints can be made.

When the edition is complete, the matrix - a block, plate, stone, mylar, or other - is effected, crossed out or otherwise "cancelled". An impression is then taken from this matrix, showing that the plate has been "cancelled". This ensures that no further uncancelled impressions can be pulled.
