RisographRisograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation. Introduced in Japan in 1980, it is intended mainly for high-volume photocopying and printing. It is sometimes called a printer-duplicator as newer models can be used as a network printer as well as a stand-alone duplicator.
MimeographType of duplicating machine A hand-cranked mimeograph machine used in Poland by opponents of the communist regime after 1981. A mimeograph machine (the term often being abbreviated to mimeo), sometimes called a stencil duplicator or stencil machine, is a low-cost duplicating machine that works by forcing ink through a stencil onto paper. The process is called mimeography, and a copy made by the process is a mimeograph.
PhotocopierA photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply. Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image.
Duplicating machinesDuplicating machines were the predecessors of modern document-reproduction technology. They have now mostly been replaced by digital duplicators, scanners, laser printers, and photocopiers, but for many years they were the primary means of reproducing documents for limited-run distribution.
Offset printingOffset printing (offset lithography) 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.
Soy inkSoy ink is a plant-based ink made from soybeans (Glycine max). Developed as an alternative to petroleum-based inks, it offers reduced volatile organic compound (VOC) emissions, lower environmental toxicity, and facilitates easier de-inking during paper recycling. Because highly refined soybean oil is naturally clearer than petroleum distillates, soy ink can produce bright, precise colors with less pigment.
GestetnerThe Gestetner is a type of duplicating machine named after its inventor, David Gestetner (1854–1939). During the 20th century, the term Gestetner was used as a verb—as in Gestetnering. The Gestetner company established its base in London, filing its first patent in 1879. The business grew, remaining within the control of the Gestetner family, and acquiring other businesses. In 1995, the Gestetner company was acquired by the Ricoh Corporation of Japan.
Riso Kagaku CorporationRiso Kagaku Corporation (理想科学工業株式会社, Risō Kagaku Kōgyō Kabushiki-gaisha) is a Japanese corporation which is the inventor, manufacturer, and distributor of the RISO Printer-Duplicator, a.k.a. Risograph. This device automatically creates a stencil-type master (from a paper original or digital file), thereby enabling it reproduce single-colour documents at high speed and low cost, in a machine that has a small footprint and a relatively low purchase price.
Laser printingElectrostatic digital printing process HP LaserJet 4200 series printer, installed atop additional 500-sheet paper tray Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.
Print GoccoPrint Gocco (プリントゴッコ, Purinto Gokko) was a compact, self-contained card printing system developed by Riso Kagaku Corporation and first sold in 1977. Print Gocco achieved significant success and sold over 10 million units cumulatively before production ceased in 2008. The system was developed for the Japanese custom of sending New Year's Day postcards (年賀状, nengajō) to friends and relatives.Inkjet printingType of computer printing A typical inkjet printer Inkjet printing is a type of computer printing that recreates a digital image by propelling very fine droplets of ink onto various substrates such as paper, plastic, wood and metal.
Printer (computing)A printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers.*As an Amazon Associate I earn from qualifying purchases.
