Analysis of the current situation of paper printing in China

in recent years, the market demand for lightweight coated paper in China has been rising. At the same time, it is also one of the products that various paper mills pay attention to and focus on. Domestic enterprises producing light coated paper mainly include Chenming Paper Group, Jindong paper, Shandong Huatai Group, UPM group, Ningxia Meili Paper, Shandong Quanlin paper and other paper enterprises. In October 2002, app (Asia Pulp company) Jiangsu Zhenjiang Jindong Paper Co., Ltd. built the second coated paper production line with an annual output of 500000 tons. The common problems and solutions of the universal friction and wear testing machine are introduced in detail below. So far, together with the first coated paper production line originally built, Jindong Paper Co., Ltd. has become the largest coated paper production enterprise in the world. The company has two coated base paper production lines with a width of 9700mm and a speed of 1500m/min, with an annual production capacity of more than 700000 tons. The quality of base paper and coated paper are high-quality products. Since Chenming Paper Group successfully developed 51 g/m2 low weight coated paper, it has the production capacity to produce 51 ~ 120 g/m2 low weight coated paper of various specifications, and the product structure is complete

light coated paper has good printability. It is suitable for rotary gravure printing or rotary offset printing, and even lithographic offset printing (light coated paper with high quantity). At present, light coated paper is widely used in printing magazines, catalogues, advertisements, trademarks, newspaper specials (inserts) and other fields. In the United States, light coated paper is listed as the most potential paper by the development guide of new products in light industry. According to statistics, 52% of the light coated paper in the United States is used to print magazines. For example, reader's Digest is printed in 19 languages and distributes tens of millions of copies per issue. The main body of this magazine is printed on light coated paper. In addition, 25% of light coated paper is used for catalogues. 20% of printed advertisements. In Europe, 42% of light coated paper is used for printing magazines, 30% for advertising and 22% for catalogues. Japan's medium and low-grade lightweight coated paper is also the paper with the fastest export growth in recent years, and has a trend of continuous increase. In more developed countries and regions, the increasing demand for light coated paper is mainly due to the great impetus generated by the development of advertising and color printing

China's low weight coated paper started late. Coated paper is mostly used in commercial advertisements, which is rare in the international market. Coated paper produced by full chemical pulp base paper is rarely used abroad. In the past, the domestic light coated paper was mostly used for magazine printing, newspaper inserts and other fields. In recent years, the trend of using light coated paper printing has gradually appeared in the commodity catalogue and advertising industry, which makes the domestic light coated paper market more active since entering the 21st century, and the consumption and demand are increasing year by year. In 2002, the domestic self-produced light coated paper was about 250000 tons. The national consumption reached 900000 tons, and the insufficient part was imported from abroad. It can be seen that the domestic low weight coated paper market has broad development space

At present, coated paper has become a hot topic in printing at home and abroad. Although there have been changes and deformations within the elastic range in China in recent years, more than 10 light coated paper production lines have been built in succession. Although the annual production capacity has been more than 1 million tons, the output has been less than 500000 tons for many years, and the development speed is slow. In foreign countries, lightweight coated paper is the fastest growing paper product in recent years. The reason is that foreign lightweight coated paper has the characteristics of basically unchanged or slightly decreased product printing performance, but greatly reduced cost, so the market is becoming larger and larger. At present, if the domestic cultural paper wants to change from the book paper and double offset paper, which are the main products in the market, to light coated paper, it is a process in which the printing performance of the product has been improved, but the cost has been greatly increased, which leads to the slow development of the domestic light coated paper market. The research and development technology of light coated paper is still developing, from coating pigment. Coating technology is the best choice. The further renewal of coating equipment to the further reduction of the quantitative of light coated paper base paper. The focus of in-depth research should still be to reduce or control the cost as much as possible while improving or ensuring its printing performance. In China, cheap non wood fibers can be used, such as bamboo pulp, bagasse pulp and reed pulp, to replace the mechanical pulp components in foreign light coated paper. The rational use of chemical wood pulp can produce light coated and other cultural paper that can meet the market demand, so as to realize the upgrading of cultural paper. Only the light weight coated paper with quality meeting the market demand and low cost is the real favorite of domestic printing paper products now and in the future
