Lithography in the context of "Portrait painting"

A category of fine art, graphic art covers a broad range of visual artistic expression, typically two-dimensional graphics, i.e. produced on a flat surface, today normally paper or a screen on various electronic devices. The term usually refers to the arts that rely more on line, color or tone, especially drawing and the various forms of engraving; it is sometimes understood to refer specifically to drawing and the various printmaking processes, such as line engraving, aquatint, drypoint, etching, mezzotint, monotype, lithography, and screen printing (silk-screen, serigraphy). Graphic art mostly includes calligraphy, photography, painting, typography, computer graphics, and bindery. It also encompasses drawn plans and layouts for interior and architectural designs.

In museum parlance "works on paper" is a common term, covering the various types of traditional fine art graphic art. There is now a large sector of graphic designers working mostly on web design.

Printmaking is the process of creating artworks by printing, normally on paper, but also on fabric, wood, metal, and other surfaces. "Traditional printmaking" normally covers only the process of creating prints using a hand processed technique, rather than a photographic reproduction of a visual artwork which would be printed using an electronic machine (a printer); however, there is some cross-over between traditional and digital printmaking, including risograph.

Prints are created by transferring ink from a matrix to a sheet of paper or other material, by a variety of techniques. Common types of matrices include: metal plates for engraving, etching and related intaglio printing techniques; stone, aluminum, or polymer for lithography; blocks of wood for woodcuts and wood engravings; and linoleum for linocuts. Screens made of silk or synthetic fabrics are used for the screen printing process. Other types of matrix substrates and related processes are discussed below.

Aquatint is an intaglio printmaking technique, a variant of etching that produces areas of tone rather than lines. For this reason it has mostly been used in conjunction with etching, to give both lines and shaded tone. It has also been used historically to print in colour, both by printing with multiple plates in different colours, and by making monochrome prints that were then hand-coloured with watercolour. The term colour etching, frequently used in the art trade, is potentially ambiguous, but most often means one of these two options.

It has been in regular use since the later 18th century, and was most widely used between about 1770 and 1830, when it was used both for artistic prints and decorative ones. After about 1830 it lost ground to lithography and other techniques. There have been periodic revivals among artists since then. An aquatint plate wears out relatively quickly, and is less easily reworked than other intaglio plates. Many of Goya's plates were reprinted too often posthumously, giving very poor impressions.

Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing evolved from ink rubbings made on paper or cloth from texts on stone tablets, used during the sixth century. Printing by pressing an inked image onto paper (using woodblock printing) appeared later that century. Later developments in printing technology include the movable type invented by Bi Sheng around 1040 and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.

Printing emerged as early as the 4th millennium BCE in the form of cylinder seals used by the Proto-Elamite and Sumerian civilizations to certify documents written on clay tablets. Other early forms include block seals, hammered coinage, pottery imprints, and cloth printing. Initially a method of printing patterns on cloth such as silk, woodblock printing for texts on paper originated in Tang China by the 7th century, to the spread of book production and woodblock printing in other parts of Asia such as Korea and Japan. The Chinese Buddhist Diamond Sutra, printed by woodblock on 11 May 868, is the earliest known printed book with a precise publishing date. Movable type was invented in China during the 11th century by the Song dynasty artisan Bi Sheng, but it received limited use compared to woodblock printing. However, the use of copper movable types was documented in a Song-era book from 1193, and the earliest printed paper money using movable metal type to print the identifying codes were made in 1161. The technology also spread outside China, with the oldest extant printed book using metal movable type being the Jikji, printed in Korea in 1377 during the Goryeo era.

Woodblock printing was also used in Europe until the mid-15th century. Late medieval German inventor Johannes Gutenberg created the first printing press based on previously known mechanical presses and a process for mass-producing metal type. By the end of the 15th century, his invention and widescale circulation of the Gutenberg Bible became responsible for a burgeoning economical book publishing industry spreading globally across Renaissance Europe and eventually among the colonial publishers and printers that emerged in the British American colonies. This industry enabled the communication of ideas and the sharing of knowledge on an unprecedented scale, leading to the global spread of the printing press during the early modern period. Alongside the development of text printing, new and lower-cost methods of image reproduction were developed, including lithography, screen printing and photocopying.

Jean-Louis André Théodore Géricault (French: [ʒɑ̃lwi ɑ̃dʁe teɔdɔʁ ʒeʁiko]; 26 September 1791 – 26 January 1824) was a French painter and lithographer. His best-known painting is The Raft of the Medusa. Despite his short life, he was one of the pioneers of the Romantic movement.

Gum arabic (gum acacia, gum sudani, Senegal gum and by other names) is a tree gum exuded by two species of Acacia sensu lato: Senegalia senegal, and Vachellia seyal. However, the term "gum arabic" does not indicate a particular botanical source. The gum is harvested commercially from wild trees, mostly in Sudan (about 70% of the global supply) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (al-samgh al-'arabi) was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports and retained its name of origin.

Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient in traditional lithography and is used in printing, paints, glues, cosmetics, and various industrial applications, including viscosity control in inks and in textile industries.
