In computing, a printer is a peripheral machine which makes a persistent representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers.
Cyan is the color between blue and green on the visible spectrum of light. It is evoked by light with a predominant wavelength between 490 and 520 nm, between the wavelengths of green and blue.
Screen printing is a printing technique where a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed. One colour is printed at a time, so several screens can be used to produce a multi-coloured image or 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 ; however, there is some cross-over between traditional and digital printmaking, including risograph.
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 appeared later that century. Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD 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.
Roy Fox Lichtenstein was an American pop artist. During the 1960s, along with Andy Warhol, Jasper Johns, and James Rosenquist, he became a leading figure in the new art movement. His work defined the premise of pop art through parody. Inspired by the comic strip, Lichtenstein produced precise compositions that documented while they parodied, often in a tongue-in-cheek manner. His work was influenced by popular advertising and the comic book style. His artwork was considered to be "disruptive". He described pop art as "not 'American' painting but actually industrial painting". His paintings were exhibited at the Leo Castelli Gallery in New York City.
Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. "Halftone" can also be used to refer specifically to the image that is produced by this process.
Dye-sublimation printing is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate.
Dots per inch is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm). Similarly, dots per centimetre refers to the number of individual dots that can be placed within a line of 1 centimetre (0.394 in).
Thermal-transfer printing is a digital printing method in which material is applied to paper by melting a coating of ribbon so that it stays glued to the material on which the print is applied. It contrasts with direct thermal printing, where no ribbon is present in the process.
Offset printing is a common printing technique in which the inked image is transferred from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier. Ink rollers transfer ink to the image areas of the image carrier, while a water roller applies a water-based film to the non-image areas.
Color printing or colour printing is the reproduction of an image or text in color.
The history of printing starts as early as 3000 BCE, when the proto-Elamite and Sumerian civilizations used cylinder seals to certify documents written in 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 China by the 7th century during the Tang dynasty, leading 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 by Chinese artisan Bi Sheng in the 11th century during the Song dynasty, 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.
Whaam! is a 1963 diptych painting by the American artist Roy Lichtenstein. It is one of the best-known works of pop art, and among Lichtenstein's most important paintings. Whaam! was first exhibited at the Leo Castelli Gallery in New York City in 1963, and purchased by the Tate Gallery, London, in 1966. It has been on permanent display at Tate Modern since 2006.
Little Big Painting is a 1965 oil and Magna on canvas pop art painting by Roy Lichtenstein. It is part of the Brushstrokes series of artworks that include several paintings and sculptures. It is located at the Whitney Museum of American Art in New York City. As with all of his Brushstrokes works, it is in part a satirical response to the gestural painting of abstract expressionism.
Girl with Ball is a 1961 painting by Roy Lichtenstein. It is an oil on canvas Pop art work that is now in the collection of the Museum of Modern Art, after being owned for several decades by Philip Johnson. It is one of Lichtenstein's earliest Pop art works and is known for its source, which is a newspaper ad that ran for several decades and which was among Lichtenstein's earliest works sourced from pop culture.
Look Mickey is a 1961 oil on canvas painting by Roy Lichtenstein. Widely regarded as the bridge between his abstract expressionism and pop art works, it is notable for its ironic humor and aesthetic value as well as being the first example of the artist's employment of Ben-Day dots, speech balloons and comic imagery as a source for a painting. The painting was bequeathed to the Washington, D.C., National Gallery of Art upon Lichtenstein's death.
Big Painting No. 6 is a 1965 oil and Magna on canvas painting by Roy Lichtenstein. Measuring 235 cm × 330 cm, it is part of the Brushstrokes series of artworks that includes several paintings and sculptures whose subject is the actions made with a house-painter's brush. It set a record auction price for a painting by a living American artist when it sold for $75,000 in 1970. The painting is in the Kunstsammlung Nordrhein-Westfalen collection.
Drowning Girl is a 1963 American painting in oil and synthetic polymer paint on canvas by Roy Lichtenstein, based on original art by Tony Abruzzo. The painting is considered among Lichtenstein's most significant works, perhaps on a par with his acclaimed 1963 diptych Whaam!. One of the most representative paintings of the pop art movement, Drowning Girl was acquired by the Museum of Modern Art in 1971.
Brushstrokes series is the name for a series of paintings produced in 1965-1966 by Roy Lichtenstein. It also refers to derivative sculptural representations of these paintings that were first made in the 1980s. In the series, the theme is art as a subject, but rather than reproduce masterpieces as he had starting in 1962, Lichtenstein depicted the gestural expressions of the painting brushstroke itself. The works in this series are linked to those produced by artists who use the gestural painting style of abstract expressionism made famous by Jackson Pollock, but differ from them due to their mechanically produced appearance. The series is considered a satire or parody of gestural painting by both Lichtenstein and his critics. After 1966, Lichtenstein incorporated this series into later motifs and themes of his work.
