Approval Proofer
Within the printing industry, the Approval proofer, also known as the Approval Digital Imaging System or Kodak Approval System, was designed for use in Prepress proofing, especially for the highest quality contract proofs. The Approval is a laminate based system where up to 6 color donors can transfer images to a receiver sheet by a high-powered laser. Once imaging is complete the image can be transfer to a wide variety of substrates including papers, boards, shrink wrap, plastics, metals, etc. The system comes in two sizes: The 3-page model images a proof 13.3 × 20.9 in. (338 × 530 mm); the 4-page model images a proof 26.6 × 20.9 in. (676 × 530 mm) The Approval is similar to the Fuji Finalproof product. Another similar lamination device is the Creo Spectrum [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printing Industry
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 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.

Stochastic Screening
Stochastic screening or FM screening is a halftone process based on pseudo-random distribution of halftone dots, using frequency modulation (FM) to change the density of dots according to the gray level desired. Traditional amplitude modulation halftone screening is based on a geometric and fixed spacing of dots, which vary in size depending on the tone color represented (for example, from 10 to 200 micrometres). The stochastic screening or FM screening instead uses a fixed size of dots (for example, about 25 micrometres) and a distribution density that varies depending on the color’s tone. The strategy of stochastic screening, which has existed since the seventies, has had a revival in recent times thanks to increased use of computer-to-plate (CTP) techniques. In previous techniques, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EskoArtwork
Esko, formerly called ''EskoArtwork'', is a graphic arts company producing prepress software and hardware for the packaging and labels, sign and display and publishing industries. History Esko was the result of a merger between '' Barco Graphics'' and '' Purup-Eskofot A/S'' in 2001. The merged company was called Esko-Graphics but was renamed Esko in 2006. In the fall of 2005, Esko became fully owned by Axcel, a Danish private equity investment company. In August 2007 Esko announced that it was 'joining forces' with Artwork Systems Group NV (AWS), its chief competitor in the packaging prepress market. Esko initially bought 76.69% of AWS shares for €196 million. Enfocus, a brand of PDF pre-flighting and workflow software originally acquired by Artwork Systems in 2000, became a subsidiary of the combined EskoArtwork company. Reflecting the merger, Esko changed its name to EskoArtwork. It also introduced a new logo, though it is visually very close to the Esko original. In Janua ...

Prinergy
Prinergy is a prepress workflow system created by Creo in 1999 and maintained and sold through Kodak. It is a client/server system that integrates PDF creation, job proofing, imposition, and a raster image processor (RIP) into one unified workflow. History Creo was the leading manufacturer of computer-to-plate technology in the 1990s, using thermal laser technology to capture a significant market share of the offset prepress industry. Because computer to plate technology allowed printers to image large numbers of plates at great speed, there arose a corresponding need to engineer a workflow that could process large amounts of data to feed the platemakers and ultimately the offset presses. Prinergy was code-named Araxi (a restaurant in Whistler, British Columbia) when it was conceived of in 1995, on a train trip returning from Düsseldorf after Drupa 1995. The Prinergy product name was chosen a few months before the product was launched. The name was created bnamebase based on a ...

Kodak Proofing Software
Kodak Proofing Software is an application from Eastman Kodak for managing and controlling the process of Prepress proofing. It supports the Veris printer, Kodak Approval and various inkjet printers from Epson and Hewlett Packard. The four dots: blue/yellow, red/green used in the splash screen and application icon are a symbolic representation of the Lab color space central to color management technology. History Kodak Proofing Software is derived from the original Creo software used to control the Veris printer. In 2005 Kodak purchased Creo and the software first became ''internally'' known as Kodak Proofing Software, whereas Kodak Veris, Kodak APPROVAL and Kodak MATCHPRINT Inkjet are the proofing solutions marketed to customers. Veris 1.6 was released in 2004 by Creo. Much of the actual functionality of the Veris printer is actually embedded in the Veris software. Compared to conventional drop-on-demand inkjet printers the Veris hardware is quite 'dumb' relying on the control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substrate (materials Science)
Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. This surface could be used to produce new film or layers of material such as deposited coatings. It could be the base to which paint, adhesives, or adhesive tape is bonded. A typical substrate might be rigid such as metal, concrete, or glass, onto which a coating might be deposited. Flexible substrates are also used. With all coating processes, the condition of the surface of the substrate can strongly affect the bond of subsequent layers. This can include cleanliness, smoothness, surface energy, moisture, etc. Some substrates are anisotropic with surface properties being different depending on the direction: examples include wood and paper products. Coatings Coating can be by a variety of processes: * Adhesives and Adhesive tapes * Coating and printing processes * Chemical vapor deposition and physical vapor deposition * Conversion coating :* ...

Inkjet Printer
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals. The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. While working at Canon in Japan, Ichiro Endo suggested the idea for a "Bubble jet" printer, while around the same time Jon Vaught at HP was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP) and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Eps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magenta
Magenta () is a color that is variously defined as pinkish- purplish- red, reddish-purplish-pink or mauvish- crimson. On color wheels of the RGB (additive) and CMY (subtractive) color models, it is located exactly midway between red and blue. It is one of the four colors of ink used in color printing by an inkjet printer, along with yellow, black, and cyan, to make all other colors. The tone of magenta used in printing is called "printer's magenta". It is also a shade of purple. Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it ''fuchsine''. It was renamed to celebrate the Italian-French victory at the Battle of Magenta fought between the French and Austrians on 4 June 1859 near the Italian town of Magenta in Lombardy. A virtually identical color, called roseine, was created in 1860 by two British chemists, Chambers Nicolson and George Maule. The web color magenta is also ca ...

Cyan
Cyan () is the color between green and blue 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. In the subtractive color system, or CMYK color model, which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta and yellow. In the additive color system, or RGB color model, used to create all the colors on a computer or television display, cyan is made by mixing equal amounts of green and blue light. Cyan is the complement of red; it can be made by the removal of red from white. Mixing red light and cyan light at the right intensity will make white light. Colors in the cyan color range are teal, turquoise, electric blue, aquamarine, and others described as blue-green. Etymology and terminology Its name is derived from the Ancient Greek word ''kyanos'' (κύανος), meaning "dark blue enamel, Lapis lazu ...

Dot Gain
Dot gain, or tonal value increase, is a phenomenon in offset lithography and some other forms of printing which causes printed material to look darker than intended. It is caused by halftone dots growing in area between the original printing film and the final printed result. In practice, this means that an image that has not been adjusted to account for dot gain will appear too dark when it is printed. Dot gain calculations are often an important part of a CMYK color model. Definition It is defined as the increase in the area fraction (of the inked or colored region) of a halftone dot during the prepress and printing processes. Total dot gain is the difference between the dot size on the film negative and the corresponding printed dot size. For example, a dot pattern that covers 30% of the image area on film, but covers 50% when printed, is said to show a total dot gain of 20%. However, with today's computer-to-plate imaging systems, which eliminates film completely, the measure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moiré Pattern
In mathematics, physics, and art, moiré patterns ( , , ) or moiré fringes are large-scale interference patterns that can be produced when an opaque ruled pattern with transparent gaps is overlaid on another similar pattern. For the moiré interference pattern to appear, the two patterns must not be completely identical, but rather displaced, rotated, or have slightly different pitch. Moiré patterns appear in many situations. In printing, the printed pattern of dots can interfere with the image. In television and digital photography, a pattern on an object being photographed can interfere with the shape of the light sensors to generate unwanted artifacts. They are also sometimes created deliberately – in micrometers they are used to amplify the effects of very small movements. In physics, its manifestation is wave interference such as that seen in the double-slit experiment and the beat phenomenon in acoustics. Etymology The term originates from '' moire'' (''moiré ...

Halftone Screening
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.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 interprets the patterned areas as if they were smooth tones. At a microscopic level, developed black-and-white photographic film also consists of only two colors, and not an infinite range of continuous tones. For details, see film grain.
