    Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking

    Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engravings, a form of relief printing and stone engravings, such as petroglyphs, are not covered in this article.

    Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning the technique, is much less common in printmaking, where it has been largely replaced by etching and other techniques.

    Other terms often used for printed engravings are copper engraving, copper-plate engraving or line engraving. Steel engraving is the same technique, on steel or steel-faced plates, and was mostly used for banknotes, illustrations for books, magazines and reproductive prints, letterheads and similar uses from about 1790 to the early 20th century, when the technique became less popular, except for banknotes and other forms of security printing. Especially in the past, "engraving" was often used very loosely to cover several printmaking techniques, so that many so-called engravings were in fact produced by totally different techniques, such as etching or mezzotint. "Hand engraving " is a term sometimes used for engraving objects other than printing plates, to inscribe or decorate jewellery, firearms, trophies, knives and other fine metal goods. Traditional engravings in printmaking are also "hand engraved", using just the same techniques to make the lines in the plate.

    Engravers use a hardened steel tool called a burin, or graver, to cut the design into the surface, most traditionally a copper plate. However, modern hand engraving artists use burins or gravers to cut a variety of metals such as silver, nickel, steel, brass, gold, and titanium, in applications ranging from weaponry to jewellery to motorcycles to found objects. Modern professional engravers can engrave with a resolution of up to 40 lines per mm in high grade work creating game scenes and scrollwork. Dies used in mass production of molded parts are sometimes hand engraved to add special touches or certain information such as part numbers.

    In addition to hand engraving, there are engraving machines that require less human finesse and are not directly controlled by hand. They are usually used for lettering, using a pantographic system. There are versions for the insides of rings and also the outsides of larger pieces. Such machines are commonly used for inscriptions on rings, lockets and presentation pieces.
    Gravers come in a variety of shapes and sizes that yield different line types. The burin produces a unique and recognizable quality of line that is characterized by its steady, deliberate appearance and clean edges. The angle tint tool has a slightly curved tip that is commonly used in printmaking. Florentine liners are flat-bottomed tools with multiple lines incised into them, used to do fill work on larger areas or to create uniform shade lines that are fast to execute. Ring gravers are made with particular shapes that are used by jewelry engravers in order to cut inscriptions inside rings. Flat gravers are used for fill work on letters, as well as "wriggle" cuts on most musical instrument engraving work, remove background, or create bright cuts. Knife gravers are for line engraving and very deep cuts. Round gravers, and flat gravers with a radius, are commonly used on silver to create bright cuts (also called bright-cut engraving), as well as other hard-to-cut metals such as nickel and steel. Square or V-point gravers are typically square or elongated diamond-shaped and used for cutting straight lines. V-point can be anywhere from 60 to 130 degrees, depending on purpose and effect. These gravers have very small cutting points. Other tools such as mezzotint rockers, roulets and burnishers are used for texturing effects. Burnishing tools can also be used for certain stone setting techniques.

    Musical instrument engraving on American-made brass instruments flourished in the 1920s and utilizes a specialized engraving technique where a flat graver is "walked" across the surface of the instrument to make zig-zag lines and patterns. The method for "walking" the graver may also be referred to as "wriggle" or "wiggle" cuts. This technique is necessary due to the thinness of metal used to make musical instruments vers…

    The first evidence for hominids engraving patterns is a chiselled shell, dating back between 540,000 and 430,000 years, from Trinil, in Java, Indonesia, where the first Homo erectus was discovered. Hatched banding upon ostrich eggshells used as water containers found in South Africa in the Diepkloof Rock Shelter and dated to the Middle Stone Age around 60,000 BC are the next documented case of human engraving. Engraving on bone and ivory is an important technique for the Art of the Upper Paleolithic, and larger engraved petroglyphs on rocks are found from many prehistoric periods and cultures around the world.

    In antiquity, the only engraving on metal that could be carried out is the shallow grooves found in some jewellery after the beginning of the 1st Millennium B.C. The majority of so-called engraved designs on ancient gold rings or other items were produced by chasing or sometimes a combination of lost-wax casting and chasing. Engraved gem is a term for any carved or engraved semi-precious stone; this was an important small-scale art form in the ancient world, and remained popular until the 19th century. However the use of glass engraving, usually using a wheel, to cut decorative scenes or figures into glass vessels, in imitation of hardstone carvings, appears as early as the first century AD, continuing into the fourth century CE at urban centers such as Cologne and Rome, and appears to have ceased sometime in the fifth century. Decoration was first based on Greek mythology, before hunting and circus scenes became popular, as well as imagery drawn from the Old and New Testament. It appears to have been used to mimic the appearance of precious metal wares during the same period, including the application of gold leaf, and could be cut free-hand or with lathes. As many as twenty separate stylistic workshops have been identified, and it seems likely that the engraver and vessel producer were separate craftsmen.

    In the European Middle Ages goldsmiths used engraving to decorate and inscribe metalwork. It is thought that they began to print impressions of their designs to record them. From this grew the engraving of copper printing plates to produce artistic images on paper, known as old master prints, first in Germany in the 1430s. Italy soon followed. Many early engravers came from a goldsmithing background. The first and greatest period of the engraving was from about 1470 to 1530, with such masters as Martin Schongauer, Albrecht Dürer, and Lucas van Leiden.

    Thereafter engraving tended to lose ground to etching, which was a much easier technique for the artist to learn. But many prints combined the two techniques: although Rembrandt's pri…

    Examples of contemporary uses for engraving include creating text on jewellery, such as pendants or on the inside of engagement- and wedding rings to include text such as the name of the partner, or adding a winner's name to a sports trophy. Another application of modern engraving is found in the printing industry. There, every day thousands of pages are mechanically engraved onto rotogravure cylinders, typically a steel base with a copper layer of about 0.1 mm in which the image is transferred. After engraving the image is protected with an approximately 6 μm chrome layer. Using this process the image will survive for over a million copies in high speed printing presses. Engraving machines such as GUN BOW (one of the leading engraving brands) are the best examples of hand engraving tools, although this type of machine is typically not used for fine hand engraving. Some schools throughout the world are renowned for their teaching of engraving, like the École Estienne in Paris.
