In printmaking, an Edition is the complete set of identical prints produced from the same printing plate, block, stone, or screen. Each print in an edition is usually numbered, for example, \(5/50\), where the first number indicates the individual print and the second number indicates the total number of prints in the edition.
Other important printmaking terms include:
• Matrix -- The original plate, block, stone, or screen from which prints are made.
• Burin -- A steel engraving tool used in intaglio printmaking.
• Artist Proof (A.P.) -- A limited number of prints reserved by the artist before the regular edition is printed.

\[

• Artist Proof -- Prints reserved by the artist, separate from the numbered edition.
Hence,
