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.
In printing, set-off is the term given to the unwanted transfer of ink from one printed sheet to another. The problem can occur with most types of printing, and is avoided by the use of slipsheets between copies (so any ink transfer occurs onto discardable paper) or anti-set-off spray powder . The term in offset printing also refers to the ...
Print simulation. Print process simulation uses interactive simulation software to reproduce the operating conditions of complex multi-colour printing presses that often cost several million dollars. Simulators are available for different printing process technologies (Offset Sheetfed, Heatset and Coldset Web Offset; Flexographic and Gravure ...
They were also called "132-column printers". In computing, a printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. [ 1] While most output is human-readable, bar code printers are an example of an expanded use for printers. [ 2]
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. [ 1] The drum then selectively collects electrically charged ...
Dot matrix printing, [ 1] sometimes called impact matrix printing, is a computer printing process in which ink is applied to a surface using a relatively low-resolution dot matrix for layout. Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [ 2][ 3] and typically use a print head that moves back ...
Letterpress printing is a technique of relief printing for producing many copies by repeated direct impression of an inked, raised surface against individual sheets of paper or a continuous roll of paper. [ 1] 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 ...
Waterless printing is an offset lithographic printing process that eliminates the use of water or the dampening system used in conventional printing. [ 1] Unlike traditional printing presses, waterless offset presses do not use a dampening solution to clear the press of ink. [ 2] Proponents of the technology claim efficiency and ecological ...
