Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression.


In papermaking, a dilute suspension consisting mostly of separate cellulose fibres in water is drained through a sieve-like screen, so that a mat of randomly interwoven fibres is laid down. Water is further removed from this sheet by pressing, sometimes aided by suction or vacuum, or heating. Once dry, a generally flat, uniform and strong sheet of paper is achieved.

Before the invention and current widespread adoption of automated machinery, all paper was made by hand, formed or laid one sheet at a time by specialized laborers. Even today those who make paper by hand use tools and technologies quite similar to those existing hundreds of years ago, as originally developed in China and Asia, or those further modified in Europe. Handmade paper is still appreciated for its distinctive uniqueness and the skilled craft involved in making each sheet, in contrast with the higher degree of uniformity and perfection at lower prices achieved among industrial products.

While monitoring, regulations and action by concerned citizens, as well as improvements within the industry itself are limiting the worst abuses, papermaking continues to be of concern from an environmental perspective, due to its use of harsh chemicals, its need for large amounts of water, and the resulting contamination risks, as well as trees being used as the primary source of wood pulp. Paper made from other fibers, cotton being the most common, tends to be valued higher than wood-based paper.

Hemp paper had been used in China for wrapping and padding since the eighth century BCE. [1] Paper with legible Chinese writings on it has been dated to 8 BCE. [2] The traditional inventor attribution is of Cai Lun, an official attached to the Imperial court during the Han Dynasty (202 BCE-220 CE), said to have invented paper about 105 CE using mulberry and other bast fibres along with fishnets, old rags, and hemp waste. [3] Paper used as a writing medium had become widespread by the 3rd century [4] and, by the 6th century, toilet paper was starting to be used in China as well. [5] During the Tang Dynasty (618-907 CE) paper was folded and sewn into square bags to preserve the flavour of tea, [1] while the later Song Dynasty (960-1279 CE) was the first government to issue paper-printed money.

In the 8th century, papermaking spread to the Islamic world, where the process was refined, and machinery was designed for bulk manufacturing. Production began in Samarkand, Baghdad, Damascus, Cairo, Morocco, and then Muslim Spain. [6] In Baghdad, papermaking was under the supervision of the Grand Vizier Ja'far ibn Yahya. Muslims invented a method to make a thicker sheet of paper. This innovation helped transform papermaking from an art into a major industry. [7] [8] The earliest use of water-powered mills in paper production, specifically the use of pulp mills for preparing the pulp for papermaking, dates back to Samarkand in the 8th century. [9] The earliest references to paper mills also come from the medieval Islamic world, where they were first noted in the 9th century by Arabic geographers in Damascus. [10]

Traditional papermaking in Asia uses the inner bark fibers of plants. This fiber is soaked, cooked, rinsed and traditionally hand-beaten to form the paper pulp. The long fibers are layered to form strong, translucent sheets of paper. In Eastern Asia, three traditional fibers are abaca, kōzo and gampi. In the Himalayas, paper is made from the lokta plant. [11] Today, this paper is used for calligraphy, printing, book arts, and three-dimensional work, including origami. In other Southeast Asian countries, elephants are fed with large amount of starch food so that their feces can be used to make paper as well. This can be found in elephant preservation camps in Myanmar where the paper are sold to fund the operations.

In Europe, papermaking moulds using metallic wire were developed, and features like the watermark were well established by 1300 CE, while hemp and linen rags were the main source of pulp, cotton eventually taking over after Southern plantations made that product in large quantities. [11] Papermaking was originally not popular in Europe due to not having many advantages over papyrus and parchment. It wasn't until the 15th century with the invention of the movable type printing and its demand for paper that many paper mills entered production, and papermaking became an industry. [12] [13]

Modern papermaking began in the early 19th century in Europe with the development of the Fourdrinier machine. This machine produces a continuous roll of paper rather than individual sheets. These machines are large. Some produce paper 150 meters in length and 10 meters wide. They can produce paper at a rate of 100 km/h. In 1844, Canadian Charles Fenerty and German F.G. Keller had invented the machine and associated process to make use of wood pulp in papermaking. [14] This innovation ended the nearly 2,000-year use of pulped rags and start a new era for the production of newsprint and eventually almost all paper was made out of pulped wood.

Papermaking, regardless of the scale on which it is done, involves making a dilute suspension of fibres in water, called "furnish", and forcing this suspension to drain through a screen, to produce a mat of interwoven fibres. Water is removed from this mat of fibres using a press. [16]

The method of manual papermaking changed very little over time, despite advances in technologies. The process of manufacturing handmade paper can be generalized into five steps:

  1. Separating the useful fibre from the rest of raw materials. (e.g. cellulose from wood, cotton, etc.)
  2. Beating down the fibre into pulp
  3. Adjusting the colour, mechanical, chemical, biological, and other properties of the paper by adding special chemical premixes
  4. Screening the resulting solution
  5. Pressing and drying to get the actual paper

Screening the fibre involves using a mesh made from non-corroding and inert material, such as brass, stainless steel or a synthetic fibre, which is stretched in a paper mould, a wooden frame similar to that of a window. The size of the paper is governed by the open area of the frame. The mould is then completely submerged in the furnish, then pulled, shaken and drained, forming a uniform coating on the screen. Excess water is then removed, the wet mat of fibre laid on top of a damp cloth or felt in a process called "couching". The process is repeated for the required number of sheets. This stack of wet mats is then pressed in a hydraulic press. The fairly damp fibre is then dried using a variety of methods, such as vacuum drying or simply air drying. Sometimes, the individual sheet is rolled to flatten, harden, and refine the surface. Finally, the paper is then cut to the desired shape or the standard shape (A4, letter, legal, etc.) and packed. [17]

The wooden frame is called a "deckle". The deckle leaves the edges of the paper slightly irregular and wavy, called "deckle edges", one of the indications that the paper was made by hand. Deckle-edged paper is occasionally mechanically imitated today to create the impression of old-fashioned luxury. The impressions in paper caused by the wires in the screen that run sideways are called "laid lines" and the impressions made, usually from top to bottom, by the wires holding the sideways wires together are called "chain lines". Watermarks are created by weaving a design into the wires in the mould. Handmade paper generally folds and tears more evenly along the laid lines.

The International Association of Hand Papermakers and Paper Artists (IAPMA) is the world-leading association for handmade paper artists.

Handmade paper is also prepared in laboratories to study papermaking and in paper mills to check the quality of the production process. The "handsheets" made according to TAPPI Standard T 205 [18] are circular sheets 15.9 cm (6.25 in) in diameter and are tested for paper characteristics such as brightness, strength and degree of sizing. [19]

A modern paper mill is divided into several sections, roughly corresponding to the processes involved in making handmade paper. Pulp is refined and mixed in water with other additives to make a pulp slurry. The head-box of the paper machine (Fourdrinier machine) distributes the slurry onto a moving continuous screen, water drains from the slurry (by gravity or under vacuum), the wet paper sheet goes through presses and dries, and finally rolls into large rolls. The outcome often weighs several tons.

Another type of paper machine, invented by John Dickinson in 1809, makes use of a cylinder mould that rotates while partially immersed in a vat of dilute pulp. The pulp is picked up by the wire mesh and covers the mould as it rises out of the vat. A couch roller is pressed against the mould to smooth out the pulp, and picks the wet sheet off the mould. [20] [21]

Notable papermakers

While papermaking was considered a lifework, exclusive profession for most of its history, the term "notable papermakers" is often not strictly limited to those who actually make paper. Especially in the hand papermaking field there is currently an overlap of certain celebrated paper art practitioners with their other artistic pursuits, while in academia the term may be applied to those conducting research, education, or conservation of books and paper artifacts. In the industrial field it tends to overlap with science, technology and engineering, and often with management of the pulp and paper business itself.

Some well known and recognized papermakers have found fame in other fields, to the point that their papermaking background is almost forgotten. One of the most notable examples might be that of the first humans that achieved flight, the Montgolfier brothers, where many accounts barely mention the paper mill their family owned, although paper used in their balloons did play a relevant role in their success, as probably did their familiarity with this light and strong material.

Key inventors include James Whatman, Henry Fourdrinier, Heinrich Voelter and Carl Daniel Ekman, among others.

By the mid-19th century, making paper by hand was extinct in the United States. [22] By 1912, fine book printer and publisher, Dard Hunter had reestablished the craft of fine hand paper making but by the 1930's the craft had lapsed in interest again. [22] When artist Douglass Howell returned to New York City after serving in World War ll, he established himself as a fine art printmaker and discovered that art paper was in short supply. [22] During the 1940s and 1950s, Howell started reading Hunter’s books on paper making, as well as he learned about hand paper making history, conducted paper making research, and learned about printed books. [23] [24]

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.

Paper mill

A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier machine and other types of paper machine that use an endless belt, all paper in a paper mill was made by hand, one sheet at a time, by specialized laborers.

Paper machine

A paper machine is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously moving wet mat of fibre. This is dried in the machine to produce a strong paper web.

Sizing or size is a substance that is applied to, or incorporated into, other materials—especially papers and textiles—to act as a protective filler or glaze. Sizing is used in papermaking and textile manufacturing to change the absorption and wear characteristics of those materials.

Pulp mill

A pulp mill is a manufacturing facility that converts wood chips or other plant fiber source into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods. The finished product may be either bleached or non-bleached, depending on the customer requirements.

Black liquor

In industrial chemistry, black liquor is the by-product from the kraft process when digesting pulpwood into paper pulp removing lignin, hemicelluloses and other extractives from the wood to free the cellulose fibers.


A deckle is a removable wooden frame or "fence" used in manual papermaking. In a related sense, it can also mean deckle edge paper—a type of industrially produced paper with rough cut, distressed edges used in the book trade.

Korean paper

Korean paper or hanji is the name of traditional handmade paper from Korea. Hanji is made from the inner bark of Broussonetia papyrifera known colloquially as paper mulberry, a tree native to Korea that grows well on its rocky mountainsides, known in Korean as dak. The formation aid crucial to making hanji is the mucilage that oozes from the roots of Hibiscus manihot. This substance helps suspend the individual fibers in water.

Laid paper

Laid paper is a type of paper having a ribbed texture imparted by the manufacturing process. In the pre-mechanical period of European papermaking, laid paper was the predominant kind of paper produced. Its use, however, diminished in the 19th century, when it was largely supplanted by wove paper. Laid paper is still commonly used by artists as a support for charcoal drawings.

Printing and writing papers are paper grades used for newspapers, magazines, catalogs, books, notebooks, commercial printing, business forms, stationeries, copying and digital printing. About 1/3 of the total pulp and paper marked is printing and writing papers. The pulp or fibers used in printing and writing papers are extracted from wood using a chemical or mechanical process.

Paper Thin material for writing, printing, etc.

Paper is a thin sheet material produced by mechanically and/or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through 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. It is a versatile material with many uses, including printing, packaging, decorating, writing, cleaning, filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, currency and security paper and a number of industrial and construction processes.

History of paper History of paper

Paper is a thin nonwoven material traditionally made from a combination of milled plant and textile fibres. It is primarily used for writing, artwork, and packaging; it is commonly white. The first papermaking process was documented in China during the Eastern Han period traditionally attributed to the court official Cai Lun. During the 8th century, Chinese papermaking spread to the Islamic world, where pulp mills and paper mills were used for papermaking and money making. By the 11th century, papermaking was brought to Europe. By the 13th century, papermaking was refined with paper mills utilizing waterwheels in Spain. Later European improvements to the papermaking process came in the 19th century with the invention of wood-based papers.

Postage stamp paper

Postage stamp paper is the foundation or substrate of the postage stamp to which the ink for the stamp's design is applied to one side and the adhesive is applied to the other. The paper is not only the foundation of the stamp but it has also been incorporated into the stamp's design, has provided security against fraud and has aided in the automation of the postal delivery system.

Louis-Nicolas Robert was a French soldier and mechanical engineer, who is credited with a paper-making invention that became the blueprint of the Fourdrinier machine.

The history of papermaking in New York had its beginnings in the late 18th century, at a time when linen and cotton rags were the primary source of fibers in the manufacturing process. By 1850 there were more than 106 paper mills in New York, more than in any other state. A landmark in the history of papermaking in the United States was the installation of the first Fourdrinier machine in the country at a mill in Saugerties, New York, in 1827. Papermaking from ground-wood pulp began in New York in 1869, with the establishment of the Hudson River Pulp & Paper Company in Corinth and also with the work of Illustrious Remington and his sons in Watertown. The innovation and success of the Remingtons spurred further development of the industry in the state.
