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.
Since most paper is either printed or written upon, fillers are added to the pulp to fill the pores of the paper and sizing is added to make the fibers water resistant, yet both act as fillers. Unsized paper is blotting paper, making it unsuitable for printing. Fillers and sizing are added to the pulp to absorb the ink quickly, unlike pure ...
Spilman secured a patent dated February 7th, 1589 giving him a monopoly in buying materials for making white paper and preventing anyone from setting up in competition without his permission. This monopoly was extended by a further 14 years in July 1597 and effectively prevented other mills from making highly prized white paper (most rival ...

A paper machine (or paper-making 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 ...
Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high-quality paper where strength, whiteness, and resistance to yellowing are important. The kraft process can use a wider range of fiber sources than most other pulping processes.
