Copy paper. Copy paper is used for copying and laser printers. The basis weight is 70-90 g/m 2 (approximately 18-24 lb) and ISO brightness 80-96%. It is made of 90–100% virgin chemical pulp or 100% deinked pulp with total pigment content of 10-15%. The most important quality is smooth run in a copying machine / printer and good dimensional ...
The IBM 3800 is a discontinued laser printer designed and manufactured by IBM. It was the first commercially available laser printer. [ 1 ] It was a continuous form laser printer, meaning that it printed onto a continuous long sheet of paper. The 3800 was initially positioned as a line printer replacement with additional features.
e. 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 ...
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and copiers produce on every printed page that identifies the specific device that was used ...
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 evolved from ink rubbings made on paper or cloth from texts on stone ...
Gary Keith Starkweather (January 9, 1938 – December 26, 2019) [ 1 ] was an American engineer who invented the laser printer and color management. Starkweather received a B.S. in physics from Michigan State University in 1960 and an M.S. in optics from the University of Rochester in 1966. In 1969, Starkweather invented the laser printer at the ...
Operation. [] Carbonless copy paper consists of sheets of paper that are coated with micro-encapsulated dye or ink or a reactive clay. The back of the first sheet is coated with micro-encapsulated dye (referred to as a Coated Back or CB sheet). The lowermost sheet is coated on the top surface with a clay that quickly reacts with the dye to form ...
Thermal paper (often supplied in roll form, and sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color locally when exposed to heat. It is used in thermal printers, particularly in inexpensive devices such as adding machines, cash registers, and credit card terminals and small ...
