Intaglio

The process of incising a design beneath the surface of a metal or stone. Plates are inked only in the etched depressions on the plates, and then the plate surface is wiped clean. The ink is then transferred onto the paper through an etching press. The reverse of this process is known as relief printing.

Planographic

The process to print impressions from a smooth surface rather than creating incised or relief areas on the plate. The term was devised to describe lithography.

Relief

All printing processes in which the non-printing areas of the block or plate are carved, engraved, or etched away. Inks are applied onto the projected surface and transferred onto the paper. The reverse process is known as intaglio printing.

Aquatint

A printing technique capable of producing unlimited tonal gradations to re-create the broad flat tints of ink wash or watercolor drawings. This is achieved by etching microscopic cracks and pits into the image on a master plate, typically made of copper or zinc. Spanish artist Goya used this technique.

Blind

Printing using an uninked plate to produce the subtle embossed texture of a white-on-white image, highlighted by the shadow of the relief image on the uninked paper. This technique is used in many Japanese prints.

Collograph

A printing technique in which proofs are pulled from a block on which the artwork or design is built up like a collage, creating relief.

Drypoint

Printing technique of intaglio engraving in which a hard, steel needle incises lines on a metal plate, creating a burr that yields a characteristically soft and velvety line in the final print.

Engraving

A printing technique in which an intaglio image is produced by cutting a metal plate or box directly with a sharp engraving tool. The incised lines are inked and printed with heavy pressure.

Etching

A printing technique in which a metal plate is first covered with an acid-resistant material, then worked with an etching needle to create an intaglio image. The exposed metal is eaten away in an acid bath, creating depressed lines that are later inked for printing.

Iris or Giclée

A computerized reproduction technique in which the image and topography are generated from a digital file and printed by a special ink jet printer, using ink, acrylic, or oil paints. Giclée printing offers one of the highest degrees of accuracy and richness of color available in any reproduction technique.

Lithography

Printing technique using a planographic process in which prints are pulled on a special press from a flat stone or metal surface that has been chemically sensitized so that ink sticks only to the design areas and is repelled by the non-image areas. Lithography was invented in 1798 by Alois Senefelder in Germany.

Mezzotint

A reverse engraving process used on a copper or steel plate to produce illustrations in relief with effects of light and shadow. The surface of a master plate is roughened with a tool called a rocker so that if inked, it will print solid black. The areas to be white or gray in the print are rubbed down so as not to take ink. It was widely used in the 18th and 19th centuries to reproduce portraits and other paintings, but became obsolete with the introduction of photo-engraving.

Monotype

One-of-a-kind print made by painting on a sheet of metal or glass and transferring the still-wet painting onto a sheet of paper by hand or with an etching press. If enough paint remains on the master plate, additional prints can be made; however, the reprint will have substantial variations from the original image. Monotype printing is not a multiple-replica process since each print is unique.

Offset Lithography

A special photo-mechanical technique in which the image to be printed is transferred to the negative plates and printed onto paper. Offset lithography is very well adapted to color printing.

Serigraphy (Silk-screen)

A printing technique that makes use of a squeegee to force ink directly onto a piece of paper or canvas through a stencil, creating an image on a screen of silk or other fine fabric with an impermeable substance. Serigraphy differs from most other printing in that its color areas are paint films rather than printing ink stains.

Woodcut

A printing technique in which the printing surface has been carved from a block of wood. The traditional wood block is seasoned hardwood such as apple, beech, or sycamore. Woodcut is one of the oldest forms of printing, dating back to the 12th century.

Acid-free Paper or Canvas

Paper or canvas treated to neutralize its natural acidity to protect fine art and photographic prints from discoloration and deterioration.

Canvas Transfer

Art reproduction on canvas, which is created by a process such as serigraphy, photomechanical, or giclée printing. Some processes can even recreate the texture, brush strokes, and aged appearance of the original work.

Color-variant Suite

A set of identical prints in different color schemes.

Impression

Fine art made by any printing or stamping process.

Limited Edition

A limited number of identical prints numbered in succession and signed and supervised by the artist. Any additional prints have been destroyed.

Monoprint

One-of-a-kind print conceived and printed by the artist and/or under the artist's supervision.

Montage (Collage)

An artwork comprising portions of various existing images, such as from photographs or prints, and arranged so that they join, overlap or blend to create a new image.

Multiple Originals

A set of identical fine prints in which the artist personally conceived the image, created the master plates, and executed or supervised the entire printing process. Example: etching.

Multiple Reproductions

A set of identical fine prints reproducing the image of an original artwork created by a non-printing process. Example: serigraph of an oil on canvas.

Open Edition

A series of prints or objects in an art edition that has an unlimited number of copies.

Provenance

Record of ownership for a work of art, ideally from the time it left the artist's studio to its present location, thus creating an unbroken ownership history.

Remarque

Additional enhancements by the artist on some or all of the final prints within an edition.

Restrike

Additional prints made from a master plate, block, lithograph stone, etc., after the original edition has been exhausted.

Proofs (Overview)

Proofs are prints authorized by the artist in addition to the limited signed and numbered edition. The total size of an art edition consists of the signed and numbered prints plus all outstanding proofs. If a set of proofs consists of more than one print, numbers are inscribed to indicate the number of the prints within the total number of the particular type of proof, e.g., AP 5/20 means the fifth print in a set of twenty identical prints authorized as artist proofs. Proofs are generally signed by the artist as validation of the prints.

Artist's Proof (AP)

Print intended for the artist's personal use. It is common practice to reserve approximately ten percent of an edition as artist's proofs, although this figure can be higher. The artist's proof is sometimes referred to by its French épreuve d'artiste (abbreviation E.A.). Artist's proofs can be distinguished by the abbreviation AP or E.A., commonly on the lower left of the work.

Cancellation Proof

Final print made once an edition series has been finished to show that the plate has been marred/mutilated by the artist, and will never be used again to make more prints of the edition.

Hors d'Commerce Proof (HC)

Hors De Commerce prints, or HCs as they are called in the industry, are very similar to Artist Proofs except they are only available through the artist directly. Usually, there are only 25 made per edition. The artist gives these away as gifts or sells them. They are valued as Artist Proofs, or higher, since they are even more rare. The term "Hors De Commerce" means "Out of Trade" in English.

Printer's Proof (PP)

Print retained by the printer as a reference. Artists often sign these prints as a gesture of appreciation.

Trial Proof (TP)

Pre-cursor to a limited edition series, these initial prints are pulled so that the artist may examine, refine, and perfect the prints to the desired final state. Trial proofs are generally not signed.

Abstract

A 20th-century style of painting in which nonrepresentational lines, colors, shapes, and forms replace accurate visual depiction of objects, landscape, and figures. The subjects are then stylized, blurred, repetitive, or broken down into basic forms so that they become unrecognizable. Intangible subjects such as thoughts, emotions, and time are often expressed in abstract art form.

Abstract Expressionism

1940s New York painting movement based on Abstract Art. This type of painting is often referred to as action painting.

Acrylic

A fast-drying paint which is easy to remove with mineral spirits; a plastic substance commonly used as a binder for paints.

Action Painting

Any painting style calling for vigorous physical activity; specifically, Abstract Expressionism. Examples include the New York School art movement and the work of Jackson Pollock.

Art Nouveau

A painting, printmaking, decorative design, and architectural style developed in England in the 1880s. Art Nouveau, primarily an ornamental style, was not only a protest against the sterile Realism, but against the whole drift toward industrialization and mechanization, and the unnatural artifacts they produced. The style is characterized by the usage of sinuous, graceful, cursive lines, interlaced patterns, flowers, plants, insects, and other motifs inspired by nature.

Bauhaus

A design school founded by Walter Gropius in 1919 in Germany. The Bauhaus attempted to achieve reconciliation between the aesthetics of design and the more commercial demands of industrial mass production.

Chiaroscuro

In drawing, painting, and the graphic arts, chiaroscuro concerns the rendering of forms through a balanced contrast between light and dark areas. Introduced during the Renaissance. Leonardo da Vinci and Rembrandt excelled at this technique.

Classical Style

In Greek art, the style of the 5th century B.C. Loosely, the term “classical” is often applied to all the art of ancient Greece and Rome as well as to any art based on logical, rational principles and deliberate composition.

Cubism

An art style developed in 1908 by Picasso and Braque, whereby the artist breaks down the natural forms of the subjects into geometric shapes and creates a new kind of pictorial space.
