In July 2026, Ai Weiwei released a print called "A Tree." It was his first drawing in more than 50 years. The print was a one-color silkscreen with a hand-embossed border on Somerset Velvet White paper, produced by CIRCA and available for purchase between July 9 and September 9, 2026. It came with a numbered, stamped, and dated certificate of authenticity and cost 450 pounds. The edition was time-limited: anyone could buy one during the two-month window, and the total number sold would determine the edition size. This is one of several ways artists and publishers now handle editions, and it would have been unthinkable to Rembrandt, who pulled prints from copper plates in the 17th century without numbering a single one. Read about the release at New Art Editions.
An edition is a set of identical prints produced from a single matrix: a copper plate, a woodblock, a lithographic stone, a silkscreen, or a digital file. Each print in the edition is called an impression. The edition size is the total number of impressions produced, and in modern practice this number is fixed before printing begins. Each impression is numbered, typically as a fraction: the top number is the impression's position in the sequence, and the bottom number is the total edition size. A print marked "3/50" is the third impression in an edition of fifty.
This entry covers what an edition is, how the practice of numbering emerged, how edition sizes affect value, and how contemporary artists are rethinking the edition in the digital age.
What Is an Edition and How Does It Work?
An edition begins with a matrix. In etching, the matrix is a copper plate. In woodcut, it is a carved block of wood. In lithography, it is a limestone block or aluminum plate. In screen printing, it is a mesh screen with a stencil. The artist prepares the matrix, and then impressions are pulled from it. Each impression transfers the image from the matrix to paper. Because the matrix wears down slightly with each impression, prints made early in the run may be sharper than those made later, though modern materials and techniques have largely eliminated this variation.
Once the edition is printed, the matrix is typically destroyed or cancelled. A cancelled plate may be scored with a line to prevent further printing. This guarantees that no additional impressions can be pulled, preserving the scarcity that gives the edition its value. The edition size does not include artist's proofs, trial proofs, or hors commerce copies, which are produced alongside the main edition but are not numbered within it.
The numbering system is straightforward but strict. As the printmaking guide published by Artfolio in 2025 explains: "Register the edition size in your production log before the first pull. Number as you print, not afterwards, to avoid mix-ups. Issue a certificate of authenticity noting edition size, paper, ink and matrix ID." The guide also warns that exceeding the declared edition size is a breach of the implicit contract with buyers. "Limited-edition numbering rules are binding. Create a new, clearly different edition instead." Read the guide at Artfolio.
A Brief History of Editioning
Numbering editions is a recent practice. For most of printmaking's history, prints were not numbered at all. Rembrandt pulled impressions from his copper plates as he needed them, revising the plates between runs. There was no fixed edition size. Whistler produced etchings in small batches, varying the inking and paper from batch to batch. The idea that an edition should be a fixed, numbered set of identical impressions emerged in the late 19th century and became standard practice only in the mid-1960s.
The numbering system was a response to the commercialization of printmaking. As prints became collectible, buyers needed assurance that the supply was limited. A numbered edition with a declared size provides that assurance. The practice was codified by print publishers and galleries in the 1960s, particularly in the American screen printing boom led by studios like ULAE and Gemini G.E.L., which produced editions for artists like Jasper Johns, Robert Rauschenberg, and Frank Stella.
Picasso's printmaking career illustrates the transition. His early etchings and lithographs were not numbered. By the time he began working with the Mourlot studio in the 1940s and 1950s, editions were being numbered, though the practice was not yet universal. Today, a Picasso lithograph from the 1945-1949 period might carry a number like "12/50," but that number was often applied retroactively by the publisher rather than during printing.
Edition Size and Value
Edition size directly affects price. Smaller editions command higher prices because they are scarcer. According to data from the Artnet Price Database cited by Artfolio in 2025, "when the pool of impressions shrinks below fifty, the auction hammer routinely rises by triple-digit percentages, driven by pure supply-and-demand psychology." Conversely, large editions of 250 or more behave almost like open editions in the eyes of the market, with weaker resale momentum.
Contemporary practice varies widely. In 2026, the Fondation Beyeler published a photogravure edition by Pierre Huyghe called "Liminal Still Print" in an edition of 50, plus 5 artist's proofs and 10 hors commerce copies, priced at 1,500 Swiss francs each. Read the details at Fondation Beyeler Shop. HENI released a series of 12 silkscreen prints by Brian Clarke in July 2026, each in an edition of 50 plus 12 artist's proofs, priced at $1,500 to $1,800 each. Read the details at HENI Editions. The Tate St Ives sold a lithograph by Ahmet Dogu Ipek in an edition of 30, each hand-engraved by the artist, making each print unique within the edition. Read the details at Tate Shop.
The Ipek example points to a tension within the concept of an edition. An edition is supposed to be a set of identical impressions. But when the artist intervenes on each print after pulling it, as Ipek did by hand-engraving a cut on the surface of each sheet, the prints are no longer identical. They are unique works that share a common base. This hybrid practice, somewhere between an edition and a series of unique works, is increasingly common in contemporary printmaking.
Types of Editions
A limited edition has a fixed, declared number of impressions. Once the edition is complete, no more are printed. An open edition has no set limit: impressions are produced as long as there is demand. Open editions are generally less valuable because the supply is theoretically unlimited. A timed edition, like the Ai Weiwei "A Tree" release, is available for a fixed period, and the edition size is determined by how many are sold during that window. This model, enabled by digital sales platforms, creates a different kind of scarcity: the buyer does not know the final edition size at the time of purchase.
A posthumous edition is one printed after the artist's death, usually from a matrix the artist prepared during their lifetime. Posthumous editions are controversial because the artist could not approve the final impressions or supervise the printing. They are generally worth less than lifetime editions. Some catalogue raisonne projects distinguish between lifetime and posthumous impressions, as the Dallas Museum of Art did in its 2025 project to catalogue its Rembrandt print collection, identifying watermarks to distinguish the two. Read about the project at Dallas Museum of Art.
The edition is the central concept of printmaking. It is closely connected to the artist's proof, which is a print outside the numbered edition. It relates to the intaglio, relief printing, lithography, and screen printing techniques that produce editions. The catalogue raisonne documents an artist's editions, often recording the edition size, paper type, and publisher for each print.

See Editions in Person
Museum print rooms are the best place to examine editions closely. The Rijksmuseum in Amsterdam holds the largest collection of Rembrandt prints, including multiple impressions from the same plate, allowing you to see how the plate wore down over successive pulls. The Metropolitan Museum of Art in New York has extensive collections of Picasso, Matisse, and Warhol editions. The Tate in London sells contemporary editions through its shop, produced in collaboration with living artists, which provides an accessible entry point for new collectors.
