Dye-transfer Process
Dye transfer is a continuous-tone color photographic printing process. It was used to print Technicolor films, as well as to produce paper colour prints used in advertising, or large transparencies for display. History The use of dye imbibition for making full-color prints from a set of black-and-white photographs taken through different color filters was first proposed and patented by Charles Cros in 1880.Pénichon, Sylvie (2013). "Twentieth-Century Color Photographs: Identification and Care". The Getty Conservation Institute, Los Angeles. pp. 127-131. It was commercialized by Edward Sanger-Shepherd, who in 1900 was marketing kits for making color prints on paper and slides for projection. Imbibition printing was initially in monochrome. The basic underlying principle is that bichromate development of a silver gelatine photographic emulsion (not strictly a real chemical emulsion) results in the gelatine being differentially tanned or hardened in proportion to the exposure recei ...

Imbibition
Imbibition is a special type of diffusion that takes place when liquid is absorbed by solids-colloids causing an increase in volume. Water surface potential movement takes place along a concentration gradient; some dry materials absorb water. A gradient between the absorbent and the liquid is essential for imbibition. For a substance to imbibe a liquid, there must first be some attraction between them. Imbibition occurs when a wetting fluid displaces a non-wetting fluid, the opposite of drainage in which a non-wetting phase displaces the wetting fluid. The two processes are governed by different mechanisms. Imbibition is also a type of diffusion since water movement is along the concentration gradient. The seeds and other such materials have almost no water hence they absorb water easily. Water potential gradient between the absorbent and liquid imbibed is essential for imbibition. Examples One example of imbibition in nature is the absorption of water by hydrophilic colloids. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photochemical
Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm). In nature, photochemistry is of immense importance as it is the basis of photosynthesis, vision, and the formation of vitamin D with sunlight. Photochemical reactions proceed differently than temperature-driven reactions. Photochemical paths access high energy intermediates that cannot be generated thermally, thereby overcoming large activation barriers in a short period of time, and allowing reactions otherwise inaccessible by thermal processes. Photochemistry can also be destructive, as illustrated by the photodegradation of plastics. Concept Grotthuss–Draper law and Stark-Einstein law Photoexcitation is the first step in a photochemical process where the reactant is elevated ...

Inkjet
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, Epson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 lazuli". It ...

Eastmancolor
Eastmancolor is a trade name used by Eastman Kodak for a number of related film and processing technologies associated with color motion picture production and referring to George Eastman, founder of Kodak. Eastmancolor, introduced in 1950, was one of the first widely successful "single-strip colour" processes, and eventually displaced the more cumbersome Technicolor. Eastmancolor was known by a variety of names such as DeLuxe Color, Warnercolor, Metrocolor, Pathécolor, Columbiacolor, and others. For more information on Eastmancolor, see * Eastman Color Negative (ECN, ECN-1 and ECN-2), the photographic processing systems associated with Eastmancolor negative motion picture stock, and intermediate motion picture stocks (including interpositive and internegative stocks) * Eastman Color Positive (ECP, ECP-1 and ECP-2), the photographic processing systems associated with Eastmancolor positive print motion picture stock for direct projection * Color motion picture film, for background ...

Coated Paper
Coated paper (also known as enamel paper, gloss paper, and thin paper) is paper that has been coated by a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency. Various materials, including kaolinite, calcium carbonate, bentonite, and talc, can be used to coat paper for high-quality printing used in the packaging industry and in magazines. The chalk or china clay is bound to the paper with synthetic s, such as styrene-butadiene latexes and natural organic binders such as starch. The coating formulation may also contain chemical additives as dispersants, resins, or polyethylene to give water resistance and wet strength to the paper, or to protect against ultraviolet radiation. Varieties Machine-finished coated paper ''Machine-finished coated paper'' (MFC) has a basis weight of 48–80 g/m2. They have good surface properties, high print gloss and adequate sheet stiffness. MFC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mordant
A mordant or dye fixative is a substance used to set (i.e. bind) dyes on fabrics by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). It may be used for dyeing fabrics or for intensifying stains in biological specimen, cell or tissue preparations. Although mordants are still used, especially by small batch dyers, it has been largely displaced in industry by substantive dye, directs.} The term mordant comes from the Latin ''mordere'', "to bite". In the past, it was thought that a mordant helped the dye bite onto the fiber so that it would hold fast during washing. A mordant is often a polyvalency (chemistry), polyvalent metal ion, and one example is chromium (III). The resulting coordination complex of dye and ion is colloidal and can be either acidic or base (chemistry), alkaline. Common dye mordants Mordants include tannic acid, oxalic acid, alum, chrome alum, sodium chloride, and certain salt (chemistry), salts of aluminium, chrom ...

Joan The Woman
''Joan the Woman'' is a 1916 American epic silent drama film directed by Cecil B. DeMille and starring Geraldine Farrar as Joan of Arc. The film premiered on Christmas Day in 1916. This was DeMille's first historical drama. The screenplay is based on Friedrich Schiller's 1801 play ''Die Jungfrau von Orleans'' ('' The Maid of Orleans'').Aberth, John. "Chapter 6. Movies and the Maid: Joan of Arc Films". ''A Knight at the Movies''. Abingdon, Oxon: Routledge, 2012. 264–306. This film was considered to be the "first cinematic spectacle about Joan of Arc." This was the first film to use the Handschiegl Color Process (billed as the "Wyckoff-DeMille Process") for certain scenes. This process is especially noticeable in the scene of Joan burning at the stake, the use of red and yellow gave this a heightened dramatic effect. A print of the film still exists. DeMille has said that in the weeks before shooting he became obsessed with historical research, costume and set design, and castin ...

Handschiegl Color Process
The Handschiegl color process (, , App: Nov 20, 1916, Iss: May 13, 1919) produced motion picture film prints with color artificially added to selected areas of the image. Aniline dyes were applied to a black-and-white print using gelatin imbibition matrices. History of the process The process was invented in 1916 for Cecil B. DeMille's production of ''Joan the Woman'' (1917) by engraver Max Handschiegl and partner Alvin W. Wyckoff, with assistance from Loren Taylor. All three were technicians at the studio where the film was shot, Famous Players-Lasky, later Paramount Studios. The system was originally advertised as the "Wyckoff" process, and later referred to in publicity as the "DeMille-Wyckoff" process. For a time, the process was strictly used for Paramount releases only, but when Handschiegl and Wyckoff left Famous Players-Lasky, the process became known as the Handschiegl Color Process. Aside from Pathé's stencil process Pathéchrome, the Handschiegl process was the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
