Frequent Asked Questions

How is wood turned into paper-making pulp?

There are two main processes, depending on the end use of the pulp. To make mechanical pulp, the wood is first chipped (a wood chip is typically about 50mm x 30mm x 5mm in size) and then the chips are fed to a refiner which disintegrates the chips into individual fibres, by forcing them between two large ribbed disks which counter-rotate at high speed, very close together. Often the chips are first softened by heating, or soaking in caustic soda or other chemicals. Mechanical pulp is typically used in newsprint, magazine paper and paper towels. In mechanical pulping much of the lignin remains with the fibres.

Can alternative fibres be used to make paper?

Why should I use cotton fiber paper?

Behind the words and below the images, the paper you use makes an impression. The cotton fiber in Southworth Papers sends a message even before ink is applied. Its look and feel says quality, prestige and permanence. Yet Revura cotton fiber paper’s compatibility with the latest electronic imaging techniques makes it the contemporary choice. However you choose to use it, cotton fiber paper is the start of something special. While it remains the paper of choice when you are concerned about image, cotton fiber performs well in a range of roles.

Why are fine papers watermarked?

The watermark on Revura Papers is a sign of quality. It assures the user that the paper is a fine paper. The watermark generally will identify the manufacturer, the brand name and the amount of cotton fiber, if any, in the sheet. Through the use of a special roller called a “dandy roll”, the watermark is impressed inside the paper early in the manufacturing process. All Revura cotton fiber papers are watermarked signifying their fine quality and distinction.

What are the security features of the watermark?

Revura watermarked papers contain a date-code. The purpose of the date-code is to protect the integrity of the document that is printed on the paper from fraud. This is done by incorporating a special marker into the watermark. The position of the mark is usually changed annually and legal records are kept to document the date and its exact location. These marks are especially important for legal, accounting or government documents where the integrity of the document could be called into question.

What is Cover Stock?

Cover Stock includes a wide variety of fairly heavy papers, which can be made into covers for reports, catalogs, brochures, pamphlets, etc. Common weights are 65 lb. and 80 lb. with the word “Cover” typically following the number to differentiate them from Text or Writing weights.

What weight envelope should I use?

For paper that has a basis weight of 24 lb. or higher (many Revura Papers fall into this category), the correct envelope is one of equal weight to the paper. The correct weight of a matching envelope for a paper of up to 20 lb. stock should be one step heavier than the paper. For example, the proper envelope to use with 20 pound paper would be an envelope made from 24 pound stock.
