Sheet-fed Printing
Offset printing is a common printing technique in which the inked image is transferred (or "offset") 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. The modern "web" process feeds a large reel of paper through a large press machine in several parts, typically for several meters, which then prints continuously as the paper is fed through. Development of the offset press came in two versions: in 1875 by Robert Barclay of England for printing on tin and in 1904 by Ira Washington Rubel of the United States for printing on paper.

Photogravure
Photogravure (in French ''héliogravure'') is a process for printing photographs, also sometimes used for reproductive intaglio printmaking. It is a photo-mechanical process whereby a copper plate is grained (adding a pattern to the plate) and then coated with a light-sensitive gelatin tissue which had been exposed to a film positive, and then etched, resulting in a high quality intaglio plate that can reproduce detailed continuous tones of a photograph. The process was important in 19th-century photography, but by the 20th century was only used by some fine art photographers. By the mid-century it was almost extinct, but has seen a limited revival. History History of process The earliest forms of photogravure were developed by two original pioneers of photography itself, first Nicéphore Niépce in France in the 1820s, and later Henry Fox Talbot in England. Niépce was seeking a means to create photographic images on plates that could then be etched and used to make prints o ...

Rotogravure
Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated (cardboard) and other product packaging. History and development In the 19th century, a number of developments in photography allowed the production of photo-mechanical printing plates. W H Fox Talbot mentions in 1852 the use of a textile in the photographic process to create half-tones in the printing plate. A French patent in 1860 describes a reel-fed gravure press. A collaboration between Klic and Fawcett in Lancaster resulted in the founding of the Rembrandt Intaglio Printing Company in 1895, which company produced art prints. In 1906 they marketed the fi ...

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 ...

Waterless Printing
Waterless printing is an offset lithographic printing process that eliminates the water or dampening system used in conventional printing. Unlike conventional presses, waterless offset presses do not use a dampening solution to clear the press of ink. Proponents of the technology claim efficiency and ecological benefits. Method Waterless pressing employs silicone rubber-coated printing plates and specially formulated inks. Typically a temperature-control system is integrated. Waterless offset presses do not use a dampening solution to keep the plate's non-image areas free of ink. These presses function because the plate's non-image areas consist of a layer of silicon that repels ink. A waterless press resembles a conventional offset press, except the dampening system might be missing. A more common design, however, includes a dampening system to allow the press to function conventionally when needed. Direct imaging (digital) offset presses are waterless, with no dampening sys ...

Computer-to-film
Computer to film (CTF) is a print workflow involving printing from a computer straight to film through an imagesetter. Designs are typically created in Adobe Illustrator or CorelDRAW, however they can also be produced in AutoCAD, Inkscape and many other vector based CAD, design and desktop publishing software packages. An imagesetter is an ultra-high resolution large-format computer output device for CTF. For multi-coloured printing, the image is broken up into multiple layers representing each of the spot colors or the CMYK process colors, this may be split manually by the designer or separated by software in the imagesetter itself. Each color is made into its own piece of film and plate. There can be 12 or more colors used in a single production run; however, 1-6 colors are typical. From the imagesetter, the film is taken to the plate maker, where the film is laid on top of photopolymer plate material. A vacuum is then drawn to ensure tight contact between the plate and f ...

Computer-to-plate
Computer-to-plate (CTP) is an imaging technology used in modern printing processes. In this technology, an image created in a Desktop Publishing (DTP) application is output directly to a printing plate. This compares with the older technology, computer-to-film (CTF), where the computer file is output onto a photographic film. This film is then used to make a printing plate, in a similar manner to a contact proof in darkroom photography. Technology CTP methods differ according to the construction type of the imagesetter and the light source used to expose the plate surface. In terms of construction type there are three different kinds: internal drum, external drum and flat-bed imagesetters. The two main light sources used to expose the plate are ultraviolet light lamps and laser diodes. The wavelength and energy of the laser diodes depend on the type of plate that is used. This technology is mainly used in newspaper and magazine printing. Internal drum imagesetters In an internal ...

CMYK Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colo ...

Prepress
Prepress is the term used in the Printing and Publishing industries for the processes and procedures that occur between the creation of a print layout and the final printing. The prepress process includes the preparation of artwork for press, media selection, proofing, quality control checks and the production of printing plates if required. The artwork is usually delivery from the customer as a print-ready PDF file after being created in programs such as Adobe Indesign, Quark Express, Affinity Publisher or Scribus. Processes # Paper Selection is a very important step in prepress. Coated, Uncoated, Gloss, Matte, Silk, Satin, Recycled, Card, Bond or Specialist Papers are normal options available in different thicknesses such as 80gsm, 100gsm or 130gsm. # Binding Selection gives the customer multiple options for the spine of the publication such as Saddle-stitched,Perfect binding vs saddle stitching, paperspecs.com (last checked 2022-12-18) Perfect Bound or Case Bound, als ...

Los Angeles Times
The ''Los Angeles Times'' (abbreviated as ''LA Times'') is a daily newspaper that started publishing in Los Angeles in 1881. Based in the LA-adjacent suburb of El Segundo since 2018, it is the sixth-largest newspaper by circulation in the United States. The publication has won more than 40 Pulitzer Prizes. It is owned by Patrick Soon-Shiong and published by the Times Mirror Company. The newspaper’s coverage emphasizes California and especially Southern California stories. In the 19th century, the paper developed a reputation for civic boosterism and opposition to labor unions, the latter of which led to the bombing of its headquarters in 1910. The paper's profile grew substantially in the 1960s under publisher Otis Chandler, who adopted a more national focus. In recent decades the paper's readership has declined, and it has been beset by a series of ownership changes, staff reductions, and other controversies. In January 2018, the paper's staff voted to unionize and final ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
