Development of printing paper

1, to meet the requirements of multi-color, color printing;
2, increase the intensity, reduce the quantitative;
3, improve the paper's optical properties and surface properties;
4, increase the amount of fillers, pigments;
5, using a variety of effective chemical additives;
6, to meet the requirements of new printing inks, printing processes and printing equipment, with good printability and operating efficiency;
7. To create conditions for continuously expanding the use of recycled fiber pulp (DIP);
8. Develop a series of varieties to obtain a balance between use, quality and production costs.
The new varieties of mechanical pulp printing paper series can be divided into two categories: The first category is to improve, enhance and develop new types of extended non-coated machinery wood pulp printing paper based on newsprint, and the second is for color printing. New type of coated mechanical pulp printing paper used.
New types of non-coated mechanical wood pulp printing paper companies have added fillers to newsprint to improve the opacity of newsprint paper and the ink receptivity of printing inks; and to perform surface treatment on the surface of newsprint paper to prevent the offset printing process Fall out of powder. In raw materials, chemical pulp was also used as little as possible, and recycled fiber pulp was used in large quantities, and a series of new varieties such as refined newsprint, advanced newsprint, supercalendered paper, super-calendered paper for surface treatment and pigments were developed. Paper and so on.
Refined newsprint and advanced newsprint are premium newsprints with fillers and surface treatments. After this treatment, not only can the optical properties and printing performance of the paper be improved, but also the whiteness of the paper can be improved, overcoming the problem of insufficient whiteness due to the use of recycled pulp.
The surface-treated supercalender paper was surface-treated with a pre-metered size press and finished with calendered SC paper. ST/SC paper has good smoothness, gloss, and gloss contrast.
Pigment paper is a new type of mechanical pulp printing paper developed in Japan. It is called "Bitokshi" in the Japanese market. The quantification is 49-549/m, which is a cheap substitute for LWC paper. The amount of fillers and pigments on the paper surface increases, and printing performance and whiteness are improved.
New types of coating machinery wood pulp printing paper coating machinery wood pulp printing paper new varieties are: low-weight coating paper (referred to as LWC paper), film coating offset paper (referred to as FCO paper) and mechanical finishing paper (MFC paper for short) ). These varieties have good color printing performance, can be printed inserts, leaflets, coupons, catalogs. Samples and magazines and other printed materials, of which LWC paper is particularly popular in the market.
