Lumi (company)
Lumi is a Los Angeles-based company founded by Jesse Genet and Stephan Ango that offers packaging and supply chain management software. The company got its start developing Inkodye, a photo-reactive vat dye that develops its color through exposure to UV or sunlight. History Jesse Genet began experimenting with different printing techniques as a teenager in 2004, attempting to print photographs on cotton T-shirts. Unsatisfied with the results of screen printing and dye-sublimation she pursued her research and found what became a precursor to Inkodye, a chemical formula from the 1950s owned by a retired engineer. After meeting Stephan Ango while studying at Art Center College of Design, the pair acquired the chemical formula and began modernizing it. Lumi launched a Kickstarter campaign in December 2009 to fund R&D of the technology. The company raised $13,597 and rewarded its backers with wallets, bags and other products printed using the process. The project was an early s ...

Laundry Detergent
Laundry detergent is a type of detergent (cleaning agent) used for cleaning dirty laundry (clothes). Laundry detergent is manufactured in powder (washing powder) and liquid form. While powdered and liquid detergents hold roughly equal share of the worldwide laundry detergent market in terms of value, powdered detergents are sold twice as much compared to liquids in terms of volume. History From ancient times, chemical additives were used to facilitate the mechanical washing of textile fibers with water. The earliest recorded evidence of the production of soap-like materials dates back to around 2800 BC in ancient Babylon. German chemical companies developed an alkyl sulfate surfactant in 1917, in response to shortages of soap ingredients during the Allied Blockade of Germany during World War I. In the 1930s, commercially viable routes to fatty alcohols were developed, and these new materials were converted to their sulfate esters, key ingredients in the commercially imp ...

Washing Machine
A washing machine (laundry machine, clothes washer, washer, or simply wash) is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids and is performed by specialist businesses) or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid or powder form, to the wash water. History Washing by hand Laundering by hand involves soaking, beating, scrubbing, and rinsing dirty textiles. Before indoor plumbing, individuals also had to carry all the water used for washing, boiling, and rinsing the laundry from a pump, well, or spring. Water for the laundry would be hand carried, heated on a fire for washing, then poured into the tub. That made the warm soapy water precious; it would be reused, first to wash the least soiled clothing, then to wash progressively dirtier laundry. Removal of soap and water from the clothing after washing was a separate process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Negative (transparency)
The digital negative is the collective name for methods used by photographers to create negatives on transparency film for the contact printing of alternative photographic techniques. The negatives can also be enlarged using traditional gelatin silver processes, though this is usually reserved for negatives of 4x5" or larger due to quality limitations imposed by printer technology. This set of techniques is separate from the Digital negative (DNG) file format, although this format may be used to create digital negative transparencies. Uses Digital negatives are typically used with one of the alternative processes such as gum bichromate, cyanotype The cyanotype (from Ancient Greek κυάνεος - ''kuáneos'', “dark blue” + τύπος - ''túpos'', “mark, impression, type”) is a slow-reacting, economical photographic printing formulation sensitive to a limited near ultraviolet ..., or Inkodye. In these cases digital negatives are most commonly printed full siz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Van Dyke Brown (printing)
Van Dyke brown is a printing process named after Anthony van Dyck. It involves coating a canvas with ferric ammonium citrate, tartaric acid, and silver nitrate, then exposing it to ultraviolet light. The canvas can be washed with water, and hypo to keep the solutions in place. The image created has a Van Dyke brown color when it's completed, and unlike other printing methods, does not require a darkroom. The Van Dyke brown process was patented in Germany in 1895 by Arndt and Troost. It was originally called many different names, such as sepia print or brown print. It has even been called kallitype, however that process uses ferric oxalate Ferric oxalate, also known as iron(III) oxalate, is a chemical compound composed of ferric ions and oxalate ligands; it may also be regarded as the ferric salt of oxalic acid. The anhydrous material is pale yellow; however, it may be hydrated to f ... instead of ferric ammonium citrate. Concerns have been voiced about the archival qualiti ...

Cyanotype
The cyanotype (from Ancient Greek κυάνεος - ''kuáneos'', “dark blue” + τύπος - ''túpos'', “mark, impression, type”) is a slow-reacting, economical photographic printing formulation sensitive to a limited near ultraviolet and blue light spectrum, the range 300 nm to 400 nm known as UVA radiation. It produces a cyan-blue print used for art as monochrome imagery applicable on a range of supports, and for reprography in the form of blueprints. For any purpose, the process usually uses two chemicals: ferric ammonium citrate or ferric ammonium oxalate, and potassium ferricyanide, and only water to develop and fix. Announced in 1842, it is still in use. History The cyanotype was discovered, and named thus, by Sir John Herschel who in 1842 published his investigation of light on iron compounds, expecting that photochemical reactions would reveal, in form visible to the human eye, the infrared extreme of the electromagnetic spectrum detected by hi ...

Indigo
Indigo is a deep color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine, based on the ancient dye of the same name. The word "indigo" comes from the Latin word ''indicum'', meaning "Indian", as the dye was originally exported to Europe from India. It is traditionally regarded as a color in the visible spectrum, as well as one of the seven colors of the rainbow: the color between blue and violet; however, sources differ as to its actual position in the electromagnetic spectrum. The first known recorded use of indigo as a color name in English was in 1289. History ''Indigofera tinctoria'' and related species were cultivated in East Asia, Egypt, India, Bangladesh and Peru in antiquity. The earliest direct evidence for the use of indigo dates to around 4000 BC and comes from Huaca Prieta, in contemporary Peru. Pliny the Elder mentions India as the source of the dye after which it was named. It was importe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternative Process
{{unsourced, date= March 2021 The term alternative process refers to any non-traditional or non-commercial photographic printing process. Currently the standard analog photographic printing process is the gelatin silver process, and standard digital processes include the pigment print, and digital laser exposures on traditional color photographic paper. Alternative processes are often called historical, or non-silver processes. Most of these processes were invented over 100 years ago and were used by early photographers. Many contemporary photographers are revisiting alternative processes and applying new technologies (the digital negative) and practices to these techniques. Examples *Caffenol *Daguerreotype * Gum bichromate and other Pigmented Dichromated Colloids which are used to directly generate a photographic print * Platinum Process and Palladium Process * Carbon print and various similar processes which use a non-sensitive intermediate layer to generate a photograp ...

TopatoCo
The Topato Corporation (styled as TopatoCo) is a widely recognized online retailer of webcomics and related merchandise. It was established around 2004 by artist Jeffrey Rowland. History The company was started in Oklahoma in "about 2004" by artist Jeffrey Rowland after he lost his job in 2004, to help sell shirts, stickers and other merchandise linked to his webcomics. When the 2004 presidential election was won by George W. Bush, Rowland designed a satirical T-shirt and sold 1000 of them in one month. Rowland later expanded the business to ship products ordered from friends' websites, who in 2007 moved their retailing to TopatoCo. As a result of the expansion, the company later moved to Easthampton, Massachusetts. In a 2009 interview, Rowland stated that he considered the business to be "mundane" in comparison with the creative development of comics, often interfering with the time he wanted to spend doing comics. The company has been described as "perhaps the largest and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
