Printing ink and paper

In the past, we have used some imported newsprint papers, and feel that compared with imported newsprint papers, domestic papers still have certain gaps in terms of resistance to tension and smoothness, and import papers have a lot of advantages. Due to the tight international paper situation in recent years. Many paper mills in China. Controlling the cost savings from raw materials and other aspects has led to a decline in the quality of domestic newsprint this year.

Ink is mainly used domestically. Such as Taiyuan Gao, Tianjin Dongyang and Beijing Fulin special inks produced by several domestic ink companies. Especially color ink, we rarely use which product alone. Because of the ink produced by an ink company. Not every color can meet the user's requirements. But each has its own characteristics. The most suitable ink should be selected according to the printing characteristics.

After the development in recent years, the quality of domestic newsprint can basically meet the requirements. Especially in the last 3 years. With the impact of private papermaking companies on the market. It also brought some dynamism to the domestic paper market. The quality of domestic newsprint has been greatly improved. For example, newsprint produced by companies such as Chenming and Huatai is not as big as the imported paper. but. There are also some small companies to reduce costs, the ratio of raw materials can not meet the standards, resulting in insufficient paper flatness. The surface has ripples. Smoothness is also poor. It is also easy to curl after printing. The paper quality is worse.

At present, the biggest problem with domestic newsprint is that quality is unstable, and the overall use of paper is not good. Some paper rolls contain some shredded paper. And from the packaging point of view. It is also not conducive to transportation and inventory. In fact, the price of imported paper is almost the same as that of domestic paper. The reason why we chose to use a large amount of domestic paper is mainly to establish a long-term and stable cooperative relationship with domestic papermaking companies. Of course, due to the tight domestic paper market this year, price fluctuations are high. We chose a small amount of imported paper as a supplement. To ease the pressure on the company's paper.

Domestic ink is less dry. Especially the yellow ink is far from the imported ink. and. The domestic ink has a low color efficiency, the printing ink consumption is slightly larger than the imported product, and the reporting rate is relatively low.

The newspaper printing house is a service department relative to the newspaper office. Therefore, many aspects must be relocated to the newspaper office. Such as newsprint. In order to reduce costs, some newspaper companies use some low-quantitative newsprint. Printing companies can only solve this problem by adjusting the printing process. This will certainly affect the speed of printing. However, this phenomenon is also changing, especially in some metropolitan newspapers. It has been realized that in order to increase the speed of newspaper delivery and newspaper printing quality, the quality of paper is also very important. Both use better paper.
