Though wove paper was invented in the eighteenth century and laid paper is still produced, the majority of prints made prior to 1800 are on laid paper and the majority of prints made subsequently are on wove paper. In this type of print the printing ink is absorbed by the greasy design on the stone and is transferred to the paper under light pressure. Metal plates are used for intaglio prints and for some lithographs. A platemark is the rectangular ridge created in the paper of a print by the edge of an intaglio plate. Unlike a relief or planographic print, an intaglio print is printed under considerable pressure, thus creating the platemark when the paper is forced together with the plate.
Some reproductions have a false platemark.
A single print is a piece of paper upon which an image has been imprinted from a matrix . In a general sense, a print is the set of all the impressions made from the same matrix. By its nature, a print can have multiple impressions. A proof is an impression of a print pulled prior to the regular, published edition of the print. A trial or working proof is one taken before the design on the matrix is finished.
