Newsprint is a low-cost, non-archival paper consisting mainly of wood pulp and most commonly used to print newspapers and other publications and advertising material. Invented in 1844 by Charles Fenerty of Nova Scotia, Canada, it usually has an off white cast and distinctive feel. It is designed for use in printing presses that employ a long web of paper (web offset, letterpress and flexographic), rather than individual sheets of paper. Newsprint is favored by publishers and printers as it is relatively low cost (compared with paper grades used for glossy magazines and sales brochures), strong (to run through modern high-speed web printing presses) and can accept four-color printing at qualities that meet the needs of typical newspapers. Charles Fenerty began experimenting with wood pulp around 1838, making his discovery in 1844. On October 26, 1844, Fenerty took a sample of his paper to Halifax's top newspaper, the Acadian Recorder, where he had written a letter on his newly invented paper saying: Messrs. English & Blackadar, Enclosed is a small piece of PAPER, the result of an experiment I have made, in order to ascertain if that useful article might not be manufactured from WOOD. The result has proved that opinion to be correct, for—by the sample which I have sent you, Gentlemen—you will perceive the feasibility of it. The enclosed, which is as firm in its texture as white, and to all appearance as durable as the common wrapping paper made from hemp, Cotton, or the ordinary materials of manufacture is , reduced to a pulp, and subjected to the same treatment as paper is in course of being made, only with this exception, viz: my insufficient means of giving it the required pressure. I entertain an opinion that our common forest trees, either hard or soft wood, but more especially the fir, spruce, or poplar, on account of the fibrous quality of their wood, might easily be reduced by a chafing machine, and manufactured into paper of the finest kind.

Pulp (paper)

Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products. Before the widely acknowledged invention of papermaking by Cai Lun in China around 105 AD, paper-like writing materials such as papyrus and amate were produced by ancient civilizations using plant materials which were largely unprocessed.

Paper

Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses, or other vegetable sources in water, draining the water through a fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year.
