Since the 1970s, with the rapid growth of global economic development and the continuous improvement of people's culture and living standards in various countries, the printing industry has developed at a rapid pace in the world and China. With the advancement of the printing industry, printing technology and printing equipment have been constantly improved and improved. Among them, offset printing has its unique advantages, such as: fast and convenient plate making, low cost, high printing quality, wide paper usage, and shrinkable printing quantity. Datong has been gradually paid attention and development by domestic and foreign printing manufacturers, which has been rapidly and widely developed, so that offset printing occupies a dominant position in the international printing industry, and offset inks have also developed rapidly. In order to meet the needs of various printing equipment, substrates, various packaging decoration products, publications, etc., the variety of offset printing inks is increasing, the level of ink manufacturing technology is constantly improving, and the output of inks is expanding. According to relevant information, offset printing inks currently account for about 40% of the total printing inks, and this proportion will not change significantly in a considerable time.
1. Market status of offset printing inks
In recent years, with the development of the world economy and the continuous improvement of people's cultural and living standards, the ink industry in more developed countries has also developed rapidly. The printing and publishing industry and printing decoration products have gradually developed toward diversification and high-end. In order to meet the needs of users and pursue the exquisiteness and high-end of printed materials, printing plants constantly update and improve printing equipment. The emergence of high-speed, multi-color, low-pollution, high-efficiency printing equipment has prompted printing companies to continue to put forward new requirements for ink manufacturers. According to statistics, offset ink products are mainly dominated by offset printing inks, non-thermosetting offset printing inks, and news printing inks, followed by ultraviolet drying inks, infrared drying inks, etc. Synthetic paper offset printing ink, iron printing ink, anhydrous printing ink and various special printing inks.
In order to meet the user's requirements for different grades of quality and price, in various inks, according to the main requirements of printing, including: color, density, dryness, water resistance, printing speed, on-board stability and other major ink quality indicators, different grades have been launched Of inks for users to choose.
In addition, in order to protect the environment and prevent pollution, foreign printing inks have also put forward new requirements in terms of low toxicity and no pollution. Environmental protection and no pollution have been put forward by more and more users as an important requirement when purchasing inks. Received widespread attention from users.
Status of domestic ink industry
In recent years, with the development of China's printing industry, the pace of development of the domestic ink industry has also accelerated. With the introduction of a large number of imported and domestic high-speed offset presses and the use of new printing substrates (for example: offset printing is usually used in the past from coated paper , White plate paper, card paper extended to matte powder paper, such as matte paper, gold plate paper, silver plate paper, aluminum foil paper and other printing substrates), new printing processes and special requirements for post-printing processing, ink companies rely on technological progress, Continuously develop marketable new products, improve old products, product varieties are increasing, and the quality is gradually approaching the international advanced level. The updating of ink production equipment and the improvement of production process technology have also gradually received 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 develop marketable new types of offset printing ink products, such as: adapting to high-end offset printing bright and fast drying above 10,000 prints per hour Ink, cardboard ink, matte powder ink (matte paper ink), news web ink, cold-set offset web ink, ultraviolet light curable ink, offset synthetic paper ink, iron printing ink and the latest domestic heat The output of solid offset rotary ink and other products has increased year by year, and the quality has caught up with or approached the international advanced level, and has been recognized by printing customers at home and abroad. In addition to selling in the domestic market to replace the high-end inks that were imported in the past, some of them were also exported to the international market. Some high-value-added special offset printing inks have also been successfully developed to meet the requirements of special printing. At present, most of the products in the overview of offset printing ink products can be produced by major domestic ink manufacturers to meet the needs of the printing industry.
In addition, major domestic ink manufacturers attach importance to the quality standardization and internationalization of offset printing ink products, and the color of some ink products has reached the American PANTONE color standard. Ink companies passed the ISO9000 series quality management system and ISO14001 series environmental management system certification, which laid the foundation for domestic offset printing ink to participate in international market competition.
At present, environmentally friendly offset printing inks are also attracting more and more attention from printing users at home and abroad.
Second, the main gap between domestic offset printing ink and similar foreign products
Although China's offset printing inks have recently been increasing in output, the quality level of products has been improving, and the variety of ink colors has been increasing, although the gap between our production of similar ink products in industrialized countries is still large, there are still many deficiencies in quality. Meet the needs of today's printing and packaging and publishing printing. The main gaps are as follows:
1. The domestic ink quality level and packaging level still have a certain gap compared with similar products in the United States, Japan and Western European countries;
2. Ink still has gaps in printing process requirements, high-speed adaptability, product quality consistency, ink stability, etc .;
3. The development of special special inks is in a slow state, and cannot meet the printing requirements of today's rapidly developing packaging decoration. Some products are still in shortage or blank. For example: offset printing water-free ink, offset printing light-fast ink. Non-aromatic offset printing sheet ink and non-aromatic thermosetting offset printing ink still need to be further developed and improved quality;
4. The four-color printing ink suitable for high-speed overprint printing still needs to be further improved in terms of high density, high transparency, vividness and excellent overprintability;
5. Environmentally friendly offset printing ink varieties still need to be further developed.
Therefore, the problem that domestic ink manufacturers urgently need to solve is to continuously stabilize and improve the quality of existing products, improve product packaging, and improve the quality level of raw materials for ink production. Newly needed products.
3. The development trend of offset printing ink
Since the 1990s, due to the rapid development and popularization of the color desktop plate-making system, the international color printing market has undergone significant changes. The printed products are rapidly growing to color, and the printing time and quality requirements are higher. Therefore, as an economical, efficient and flexible printing method for printing high-quality prints, offset printing will remain a major printing method for a long period of time.
As one of the raw materials for offset printing, offset printing inks should be developed to meet the needs of multi-color printing, high speed, fast drying, no pollution and low consumption. We should absorb and learn from foreign advanced experience, face up to now, find the gap, catch up, and maintain our own advantages. By introducing advanced technology and equipment, we will improve China ’s ink production and equipment level, technical level and product standardization to improve offset The quality of inks is to achieve high quality and serialization of printing inks in China, and work hard for the rapid development of China's ink industry.
