Viestimateriaali

Viestimateriaali refers to a type of material used in the production of printed matter, particularly in the context of newspapers and magazines. It is a blend of wood pulp and other materials, designed to provide a smooth, white surface for printing. The primary component of viestimateriaali is wood pulp, which is derived from the pulping process of wood chips. This process involves breaking down the wood fibers into a suspension, which is then bleached to achieve a bright white color. The bleaching process can be done using various methods, including chlorine dioxide, hydrogen peroxide, or oxygen delignification.

In addition to wood pulp, viestimateriaali may also contain other materials such as fillers, which are used to improve the paper's strength and opacity. These fillers can include calcium carbonate, kaolin, or talc. The composition of viestimateriaali can vary depending on the specific requirements of the printed matter, such as the desired weight, brightness, and printability of the paper.

Viestimateriaali is used in the production of various types of printed matter, including newspapers, magazines, and catalogs. It is valued for its smooth surface, which allows for clear and sharp printing, as well as its ability to withstand the rigors of printing and distribution. The use of viestimateriaali has been a significant factor in the development of the modern printing industry, enabling the production of high-quality printed matter on a large scale.
