Ben-Day Dots
The Ben Day process is a printing and photoengraving technique for producing areas of grey or (with four-colour printing) various colours by using fine patterns of ink on the paper. It was developed in 1879 by illustrator and printer Benjamin Henry Day Jr. (son of 19th-century publisher Benjamin Henry Day). The process is commonly described in terms of Ben Day dots, but other shapes can be used, such as parallel lines or textures.Edmund F. Russ (Oct 1919"The Ben Day Process" ''Western Advertising'', Vol. 1 No. 9, pp. 5-&c, Ramsey Oppenheim Co., San Francisco Depending on the effect, colour, or optical illusion needed, small coloured dots are closely spaced, widely spaced, or overlapping. Magenta dots, for example, are widely spaced to create pink, or an interleaved pattern of cyan and yellow dots might be used to produce a medium green. The technique has been commonly used in colour comic books, especially in the mid-20th century, to inexpensively create shading and secondary c ...

Halftone
Halftone is the reprographic Reprography (a portmanteau of ''reproduction'' and ''photography'') is the reproduction of graphics through mechanical or electrical means, such as photography or xerography. Reprography is commonly used in catalogs and archives, as well as in th ... technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect.Campbell, Alastair. The Designer's Lexicon. ©2000 Chronicle, San Francisco. "Halftone" can also be used to refer specifically to the image that is produced by this process. Where continuous-tone imagery contains an infinite range of colors or greys, the halftone process reduces visual reproductions to an image that is printed with only one color of ink, in dots of differing size (pulse-width modulation) or spacing (frequency modulation) or both. This reproduction relies on a basic optical illusion: when the halftone dots are small, the human eye inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printing Processes
Printing is a process for mass reproducing text and Printmaking, 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 as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.Shelagh Vainker in Anne Farrer (ed), "Caves of the Thousand Buddhas", 1990, British Museum publications, 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.

Polka Dot
Red polka dots on a yellow background Girl wearing polka dot dress Polish ceramics German ceramics Polka dot is a pattern consisting of an array of large filled circles of the same size. Polka dots are commonly seen on children's clothing, toys, furniture, ceramics, and Central European folk art, but they appear in a wide array of contexts. The pattern rarely appears in formal contexts, and is generally confined to more playful attire such as bathing suits and lingerie. Occasionally, white-on-black small dots appear on more formal clothing. Etymology It is likely that the term originated because of the popularity of the polka dance around the same time the pattern became fashionable, just as many other products and fashions of the era also adopted the "polka" name. Usage In 1962, DC Comics introduced Polka-Dot Man with irregularly-sized and differently coloured dots. Since 1975, a red-on-white Polka-dotted jersey is awarded to the leader in the Mountain stages of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hatching (heraldry)
Hatching (sometimes called ''hachure'', from the French word) is a conventional system for monochrome denotation of heraldic armory, whereby the tinctures (colours) are represented by dots and lines. This technique is employed in cases where colours, for either aesthetic, practical or economic reasons are not reproduced – e.g. on surfaces such as woodcuts or engravings, seals and coins. Several systems of hatchings were developed during the Renaissance as an alternative to tricking, the earlier method of indicating heraldic tinctures by use of written abbreviations. The present day hatching system was developed during the 1630s by Silvester Petra Sancta and Marcus Vulson de la Colombière. Some earlier hatching methods were also developed, but did not come into wide use. Tricking is an alternative method which has the same purpose as hatching. Conventional system Genesis Hatching developed as a method of screening used by Renaissance painters. For copperplate engravers ...

Pointillism
Pointillism (, ) is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was coined by art critics in the late 1880s to ridicule the works of these artists, but is now used without its earlier pejorative connotation. The movement Seurat began with this technique is known as Neo-impressionism. The Divisionism, Divisionists used a similar technique of patterns to form images, though with larger cube-like brushstrokes. Technique The technique relies on the ability of the eye and mind of the viewer to blend the color spots into a fuller range of tones. It is related to Divisionism, a more technical variant of the method. Divisionism is concerned with color theory, whereas pointillism is more focused on the specific style of brushwork used to apply the paint. It is a technique with few serious practitioners today an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letratone
Screentone is a technique for applying textures and shades to drawings, used as an alternative to hatching. In the conventional process, patterns are transferred to paper from preprinted sheets. It is also known by the common brand names Zip-A-Tone (1937, now defunct), Chart-Pak (1949), and Letratone (1966, from LetrasetManufacturer-supplied first use date for ). A dry transfer screentone sheet consists of a flexible transparent backing, the printed texture, and a wax adhesive layer. The sheet is applied to the paper, adhesive down, and rubbed with a stylus on the backing side. The backing is then peeled off, leaving the ink adhered to the paper where pressure was applied. See also * Ben-Day dots * Dithering * Grayscale * Halftone * Stippling * Hatching Hatching (french: hachure) is an artistic technique used to create tonal or shading effects by drawing (or painting or scribing) closely spaced parallel lines.

Dither
Dither is an intentionally applied form of image noise, noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and digital video, video data, and is often one of the last stages of Audio mastering, mastering audio to a compact disc, CD. A common use of dither is converting a grayscale image to Binary image, black and white, such that the density of black dots in the new image approximates the average gray level in the original. Etymology The term ''dither'' was published in books on analog computation and hydraulically controlled guns shortly after World War II. Though he did not use the term ''dither'', the concept of dithering to reduce quantization patterns was first applied by Lawrence G. Roberts in his 1961 MIT master's thesis and 1962 article. By 1964 dither was being used in the modern sense described in this article. The technique was in use at least ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roy Lichtenstein
Roy Fox Lichtenstein (; October 27, 1923 – September 29, 1997) was an American pop artist. During the 1960s, along with Andy Warhol, Jasper Johns, and James Rosenquist among others, 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. ''Whaam!'' and '' Drowning Girl'' are generally regarded as Lichtenstein's most famous works. ''Drowning Girl'', ''Whaam!,'' and ''Look Mickey'' are regarded as his most influential works. His most expensive piece is '' Masterpiece'', which was sold for $165 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letterpress Printing
Letterpress printing is a technique of relief printing. Using a printing press, the process allows many copies to be produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper. A worker composes and locks movable type into the "bed" or "chase" of a press, inks it, and presses paper against it to transfer the ink from the type, which creates an impression on the paper. In practice, letterpress also includes other forms of relief printing with printing presses, such as wood engravings, photo-etched zinc "cuts" (plates), and linoleum blocks, which can be used alongside metal type, or wood type in a single operation, as well as stereotypes and electrotypes of type and blocks. With certain letterpress units, it is also possible to join movable type with slugs cast using hot metal typesetting. In theory, anything that is "type high" and so forms a layer exactly 0.918 in. thick between the bed and the paper can be printed using l ...

Photograph
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
