Since the 1970s, with the rapid growth of economic development on a global scale and the continuous improvement of people's culture and living standards, the printing industry has developed at a rapid pace in the world and in China. With the advancement of the printing industry, printing technology and printing equipment continue to improve and improve, especially in offset printing with its unique advantages, such as: quick and convenient plate making, low cost, high printing quality, wide range of paper use, and shrinkable printing quantity. The company has gradually been valued and developed by domestic and foreign printing manufacturers, which has enabled rapid and extensive development, which has made offset printing occupy a dominant position in the international printing industry, and offset printing inks have also developed rapidly. In order to meet the needs of various printing equipment, substrates, various packaging and decoration products, publishing and printing, etc., the variety of offset printing inks is increasing, the level of ink manufacturing technology is continuously improved, and the ink production is expanding. According to relevant information, offset printing ink currently accounts for about 40% of the total printing ink, and this ratio will not change much in a considerable period of time.
First, the market status of offset printing ink
In recent years, with the development of the world economy and the continuous improvement of the people's cultural living standards, the ink industry in the industrialized countries has also developed rapidly. The printing and publishing industry and printing and decoration products are gradually developing towards diversification and high-end. In order to meet the needs of users and pursue the exquisite and high-grade printing, the printing company constantly updates and perfects the printing equipment. The advent of high-speed, multi-color, low-pollution, and high-efficiency printing equipment has prompted printers to constantly introduce new requirements to ink manufacturers. According to statistics, in the ink production of more developed countries, offset printing ink products mainly use offset printing light fast drying ink, non-thermosetting offset printing rotary ink, news rotary ink, etc., followed by UV drying ink, infrared drying ink, Synthetic paper offset printing ink, printing iron ink, waterless printing ink and various special inks for offset printing.
In order to meet the user's requirements for different grades of quality and price, different grades of ink quality are introduced in various inks according to the main printing requirements, including: color, concentration, dryness, water resistance, printing speed, and on-board stability. The ink is available for the user to choose from.
In addition, in order to protect the environment from pollution, foreign printing inks have also put forward new requirements in terms of low toxicity and no pollution. Environmental protection and pollution-free have been proposed by more and more users as an important requirement when purchasing inks. Has been widely concerned by users.
The status quo of the domestic ink industry
In recent years, with the development of China's printing industry, the pace of development of the domestic ink industry is also accelerating, with the introduction of a large number of imported and domestic high-speed offset presses and the adoption of new printing substrates (for example: offset printing from the past commonly used coated paper) , white paper, cardboard extended to matte paper, namely matte paper, gold paper, silver paper, aluminum foil and other printing substrates), printing new technology and special requirements for post-printing processing, ink companies rely on scientific and technological progress, Constantly develop new products that are marketable, improve old products, and increase the variety of products, and the quality is gradually approaching the international advanced level. The improvement of ink production equipment and the improvement of production technology have also gradually attracted the attention of various manufacturers. In the past ten years, major domestic ink manufacturers in Tianjin, Shanghai, Hangzhou, Shenzhen, Taiyuan and other places have paid attention to collecting market information and constantly developing new offset printing ink products that are marketable, such as: adapting to high-speed offset printing and light drying per hour. Ink, cardboard ink, matte paper ink (matte paper ink), news rotary ink, cold-set offset rotary ink, UV light curing ink, offset synthetic paper ink, printing iron ink and the latest hot in China in recent years The output of solid offset printing inks and other products has increased year by year, and the quality has caught up with or is close to the international advanced level, and has been recognized by domestic and foreign printing customers. In addition to selling in the domestic market to replace the high-grade inks that were imported in the past, some of them are exported to the international market. Some high value-added special offset inks have also been successfully developed to meet the requirements of special printing. At present, most of the products in the offset printing ink product overview map can be produced by major domestic ink manufacturers, meeting the needs of the printing industry.
In addition, domestic ink manufacturers pay attention to the quality standardization and internationalization of offset ink products, and some ink products have reached the American PANTONE color standard. Ink companies passed ISO9000 series quality management system and ISO14001 series environmental management system certification laid the foundation for domestic offset printing ink to participate in international market competition.
At present, environmentally-friendly offset inks are also receiving more and more attention from domestic and foreign printing users.
Second, the main gap between domestic offset printing ink and similar foreign products
Despite the continuous increase in the production of offset printing inks in China, the quality of products continues to increase, and the variety of inks and colors is increasing. However, although the gap between the production of similar ink products in industrialized countries is still large, there are still many shortcomings in quality. Meet the needs of today's printing and publishing. The main gaps are as follows:
1. The quality level and packaging level of domestic inks still have a certain gap compared with similar products in the United States, Japan and Western Europe;
2. Ink still has gaps in printing process requirements, high-speed adaptability, product quality consistency, ink stability, etc.
3. The development of special-purpose inks is in a slow state and cannot meet the printing requirements of today's fast-developing packaging and packaging. Some products are still in short supply or blank. For example: offset waterless ink, offset printing fast ink. The non-aromatic offset sheet-fed ink and the non-aromatic thermosetting offset printing ink need to be further developed and improved in quality;
4. Four-color inks suitable for high-speed overprint printing still need to be further improved in terms of high concentration, high transparency and vividness, and excellent overprinting;
5. Environmentally friendly offset inks still need further development.
Therefore, the problem that domestic ink manufacturers need to solve urgently is to continuously stabilize and improve the quality of existing products, improve product packaging, improve the quality level of raw materials for ink production, and achieve high quality and serialization of existing products to meet market requirements and continuously develop markets. New products that are urgently needed.
Third, the development trend of offset printing ink Since the 1990s due to the rapid development and popularization of color desktop plate making system, the international color printing market has undergone significant changes, printing products to color growth, printing time and quality requirements are higher . Therefore, offset printing, as an economical, efficient and flexible way to print high-quality prints, will remain a major printing method at a very long time.
As one of the raw materials for offset printing, offset printing ink should meet the needs of printing to multi-color, high-speed, fast-drying, non-polluting and low-consumption development. We should absorb and learn from the advanced experience of foreign countries, face up to the present, find the gap, catch up, and maintain our own advantages. By introducing advanced technology and equipment, we will improve the standardization of ink production and equipment, technical level and product standardization in China, and improve offset printing. The quality grade of ink has achieved high quality and serialization for printing inks in China, and has worked hard for the rapid development of China's ink industry.
