What is lithography in printing?
Lithography is a planographic printing process utilizing the immiscibility of grease and water. In this process, ink adheres to a grease-treated image on a flat printing surface, while blank areas retain moisture to repel ink. The inked surface is then printed directly onto paper or transferred to a rubber cylinder for commercial applications.
Alois Senefelder discovered lithography in 1798 in Munich, using Bavarian limestone as a plate. By 1825, many firms employed lithography for commercial purposes. Currier & Ives became well-known for distributing popular lithographs.

How does the basic process of lithography work?
Lithography is a printing process that works on the principle that grease and water don't mix. The image is drawn on a stone or metal plate using a greasy crayon or ink. The surface is then treated with a chemical etch to protect the drawing and make the undrawn areas repel ink.
During printing, the stone is dampened with water, which the blank areas retain, and then an ink-covered roller is passed over it. The greasy image attracts the oily ink, while the wet stone repels it. The inked surface is then printed directly onto paper or offset onto a rubber cylinder, which transfers the image to the paper.

What materials are used in lithographic printing?
Lithographic printing uses the principle that grease and water do not mix. The process involves applying ink to a grease-treated image on a flat printing surface, while nonimage areas retain moisture to repel the ink.
Materials used include:
* Porous Bavarian limestone: Alois Senefelder used this originally.
* Metal plates: Zinc or aluminum can substitute for stone, though stone is superior for subtle tones and details.
* Greasy litho crayon or ink (tusche): Used for drawing or painting the image on the stone or metal plate.
* Gum arabic and nitric acid: This mixture, called the etch, protects the drawing from water and desensitizes undrawn areas to printing ink.
* Printing inks: Greasy inks are used in letterpress and offset printing.
* Various solvents: Turpentine or Lithotine is used during the washout process.
* Paper: Can be either dry or damp.
* Newsprint paper: Used when printing.
* Dampening sponge: Used to dampen the stone.
* Ink-charged roller: Used to pass over the stone and deposit ink on the greasy drawing.
* Printing paper: Placed on the stone for printing.
* Blotter: Used during printing.
* Tympan: A sheet of smooth, tough material that can withstand great pressure without stretching.
* Cheesecloth: Used to wipe down and buff the surface to a smooth, even layer.
* Liquid asphaltum or printing ink dissolved in turpentine: Used to rub the stone.
* Carborundum powder: Sprinkled over the stone to thoroughly wet it.
* Levigator: A heavy steel disk with a handle used to regrind the stone.
* Steel straightedge: Used to test the surface of the stone to make sure it is level.
* Erasers and abrasives: Used to clean smudges and dirt.
* Rosin and talcum powder: Protects the image from the etching solution.6 Britannica SourcesCreated from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles. -
Why is lithography called a "planographic" printing process?
Lithography is called a "planographic" printing process because it prints from a plane surface. As a surface process, it is categorized as planographic, distinguishing it from relief and intaglio methods. The term planographic refers to the printing process from a flat surface.
Lithography uses the concept of grease and water immiscibility. The grease-treated image on the flat printing surface receives ink, while the blank areas repel it by holding moisture. The inked surface is then printed directly on paper or onto a rubber cylinder for commercial purposes.

How has lithography been used to make art and commercial prints?
Lithography, a planographic printing process, uses the immiscibility of grease and water. The image is drawn on a stone or metal plate with a greasy crayon or ink, then fixed with an etch. The surface is dampened, and ink adheres to the greasy drawing but not the wet stone.
Lithography is used for both art and commercial prints. In the mid-1800s, artists like Honoré Daumier created thousands of designs, including newspaper caricatures. Color lithography, or chromolithography, became popular, and Henri de Toulouse-Lautrec elevated it in the 1890s. Commercial firms, such as Currier & Ives, produced popular lithographs, often hand-colored. Offset lithography is now the most popular method, printing on various materials.

How did the invention of lithography impact printing and publishing?
Lithography's invention revolutionized printing and publishing by enabling mass production, speed, and economy. Invented in 1798 by Alois Senefelder, lithography utilizes the immiscibility of grease and water. The process involves applying ink to a grease-treated image on a flat surface, which then prints directly on paper or onto a rubber cylinder for commercial applications.
By 1825, many firms employed lithography to produce commercial work and distribute popular subjects to a wide audience. The steam-driven lithographic press, perfected around 1865, further enhanced the process. Offset lithography, patented in 1853 and practically applied in the 1870s, allowed printing on diverse materials like tin, wood, cloth, and paper. Today, lithographic printing accounts for over 40% of all printing, packaging, and publishing.

Lithography, planographic printing process that makes use of the immiscibility of grease and water.
In the lithographic process, ink is applied to a grease-treated image on the flat printing surface; nonimage (blank) areas, which hold moisture, repel the lithographic ink. This inked surface is then printedâeither directly on paper, by means of a special press (as in most fine-art printmaking), or onto a rubber cylinder (as in commercial printing).
The process was discovered in 1798 by Alois Senefelder of Munich, who used a porous Bavarian limestone for his plate (hence lithography, from Greek lithos, âstoneâ). The secret of lithographic printing was closely held until 1818, when Senefelder published VollstĂ€ndiges Lehrbuch der Steindruckerey (A Complete Course of Lithography).
Fine-art lithography
The earliestâthough no longer the onlyâmethod of creating lithographs involved the use of a block of porous limestone. The method of preparing such stones for hand printing has remained substantially unchanged since Senefelderâs time. The materials and procedures of the 19th-century lithographer are duplicated in almost every respect by the contemporary hand printer. An image is drawn with tusche (a carbon pigment in liquid form) and litho crayon before the printing surface is fixed, moistened, and inked in preparation for printing. The printing itself is done on a press that exerts a sliding or scraping pressure. Because it undergoes virtually no wear in printing, a single stone can yield an almost unlimited number of copies, although in art printmaking only a specific number of prints are pulled, signed, and numbered before the stone is âcanceledâ (defaced). Techniques developed in the 20th century varied the process considerably, though many artists continue to prefer the time-honoured method.
Lithography became a popular medium among the artists who worked in France during the mid-1800s; Francisco de Goya (in voluntary exile in France), ThĂ©odore GĂ©ricault, and EugĂšne Delacroix were among the first lithographers. HonorĂ© Daumier was far more prolific, however, making about 4,000 designs, ranging from newspaper caricatures to broadsides printed on a single sheet. Daumier was one of the first lithographers to make use of the process called transfer lithography, by which the tusche drawing is made on paper instead of on the lithographic stone. The drawing is then transferred to the stone and printed in the usual way. This method, which is more convenient than working on stone, retains the paperâs texture in the final print. In the second half of the 19th century, Edgar Degas and Ădouard Manet worked in lithography, and Odilon Redon made it his principal means of expression.
Colour lithographs, called chromolithographs or oleographs, were developed in the second half of the 19th century. Although popular, they were of generally poor quality. In the hands of Henri de Toulouse-Lautrec, however, colour lithography in the 1890s reached new heights, and his example was enthusiastically followed by Paul Gauguin, Pierre Bonnard, and Ădouard Vuillard. The subtle views of the River Thames that the American expatriate artist James McNeill Whistler rendered in the late 19th century in transfer lithography stand in marked contrast to the straightforward and robust lithographs commercially produced in the United States in the mid-19th century by the firm of Currier & Ives.
In the 20th century the Norwegian Edvard Munch; the German Expressionists, especially Max Beckmann, Ernst Kirchner, and KÀthe Kollwitz; José Clemente Orozco, Diego Rivera, and Rufino Tamayo of Mexico; the Americans George Wesley Bellows, Robert Rauschenberg, and Jasper Johns; the Frenchmen Henri Matisse and Georges Rouault; and, above all, the Spaniard Pablo Picasso imbued the medium with great vitality and power.
Commercial lithography
After about 1825 many firms that utilized the lithographic process were established for producing a variety of commercial work and for distributing popular topical, historical, and religious subjects to a wide audience. The best known of these publishers was Currier & Ives of New York City. The firmâs popular lithographs were printed in black ink and were often hand coloured by an assembly line of women, each of whom applied a separate tint of watercolour.
Some good early work was done in colour lithography (using coloured inks) by Godefroy Englemann in 1837 and Thomas S. Boys in 1839, but the method did not come into wide commercial use until 1860. It then became the most popular method of colour reproduction for the remainder of the 19th century. These commercial prints were made by preparing a separate stone by hand methods for each colour (tint) to be used and printing one colour in register over another. Sometimes as many as 30 stones were employed for a single subject.
The steam-driven lithographic press was perfected by Hughes & Kimber of England in about 1865. It was introduced into the United States in 1866. These presses utilized automatic rollers to moisten and ink the stone, while the paper was pressed into contact by a revolving cylinder.
In 1853 the method known as offset lithography (or offset printing) was first patented by John Strather of England. The principle was not practically applied until the 1870s, when rubber offset rollers were used on flat-bed presses for printing on metals. In 1860 the phototransfer process was patented, enabling a photographic image on sensitized paper to be inked and transferred to the printing surface. Six years later the first lithographic halftone screen was used in England. Offset methods for printing on paper were developed in the United States shortly after 1900.
In the offset processâby far the most popular method in useâthe inked image is first printed on a rubber cylinder, which then offsets, or transfers, the image to paper or other materials. Because of the flexibility of the rubber cylinder, offset lithography can be used to print on tin, wood, cloth, leather, and rough or smooth paper. In the past, offset printing was used mainly to produce printed matterâcalendars, greeting cards, booklets, letterheads, books, magazines, newspapers, maps, posters, billboards, stamps, labels on cans, packaging, and other advertising matterâin large quantities. By the turn of the 21st century, however, an increasing number of artists, including Eugene Feldman, Hanne Darboven, Joseph Beuys, Gerhard Richter, Dieter Roth, and Kara Walker, had used the offset process to noncommercial ends.
Lithographic printing on a modern rotary offset press can produce high-quality, finely detailed impressions at high speed. It can reproduce any material that can be photographed in the platemaking process. As a result, it accounts for more than 40 percent of all printing, packaging, and publishing carried out; that percentage is more than twice the percentage produced by any other single printing process.
