Current situation and development trend of the hot

The current situation and development trend of offset printing inks 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 progress of the printing industry, printing technology and printing equipment have been constantly improved, especially offset printing, which has its unique advantages, such as fast and convenient plate making, low cost, high printing quality, wide range of paper use, large number of printing scalability, has gradually been valued and developed by printing manufacturers at home and abroad, so that it has been developed rapidly and widely, Thus, offset printing occupies a leading position in the international printing industry, and offset printing inks have also been developed rapidly. In order to meet the needs of various printing equipment, substrates, various packaging and decoration products, publishing and printing materials, the varieties of offset printing inks are increasing day by day, the level of ink manufacturing technology is constantly improving, and the output of ink is expanding day by day. According to relevant data, offset printing ink accounts for about 40% of the total printing ink at present, and this proportion will not change significantly in a considerable period of time

I. current market situation of offset printing inks

offset printing inks are a large category of printing inks. According to different printing machines, printing substrates and drying methods, offset printing inks can be roughly divided into the following types (see the overview map of the world's leading standards based on biology and biodegradation that will be established in this strategy):

2 In recent years, with the development of the world economy and the continuous improvement of people's cultural living standards, the ink industry in the more developed countries has also developed rapidly, and the printing and publishing industry and printing and decoration products have gradually developed in the direction of diversification and upscale. In order to meet the needs of users and pursue the exquisite and high-grade printing, the printing plant constantly updates and improves the printing equipment. The emergence of high-speed, multi-color, low pollution and high-efficiency printing equipment has prompted printing plants to constantly put forward new requirements to ink manufacturers. According to statistics, at present, in the ink output of more developed countries, offset ink products are mainly offset bright and fast drying ink, non thermosetting offset rotary ink, rotary ink, etc., followed by UV drying ink, infrared drying ink, synthetic paper offset ink, iron printing ink, waterless ink and various special inks for offset printing

in order to meet users' requirements for different grades of quality and price, different grades of inks are introduced according to the main requirements of printing, including color, concentration, dryness, water resistance, printing speed, on-board stability and other main ink quality indicators, so that users can fully 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 pollution-free. Environmental protection and pollution-free have been put forward as an important requirement by more and more users when purchasing inks, and have been widely concerned by users

3. Current situation 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 printing machines and the adoption of new printing substrates (for example, offset printing has expanded from the usual use of coated paper, white paper, cardboard to matte paper, that is, matte paper, gold paper, silver paper, aluminum foil and other printing substrates), With the special requirements of new printing technology and post-processing of printed products, ink enterprises rely on scientific and technological progress to constantly develop marketable new products and improve old products. The product variety is increasing day by day, and the quality is gradually approaching the international advanced level. The update of ink production equipment and the improvement of production technology have also gradually attracted the attention of manufacturers. In the past decade, major domestic ink manufacturers in Tianjin, Shanghai, Hangzhou, Shenzhen, Taiyuan and other places have paid attention to collecting market information and continuously developed marketable new offset printing ink products, such as: high-end offset printing bright and fast drying ink, cardboard ink, matte paper ink (matte paper ink), rotary ink, cold set offset printing rotary ink, UV curing ink, offset synthetic paper ink The output of iron printing ink and the latest thermosetting offset rotary ink in China in recent years has increased year by year, and the quality has caught up with or approached the international advanced level, which has been recognized by printing customers at home and abroad. In addition to selling and replacing the high-end inks that needed to be imported in the past in the domestic market, some export sales have also entered the international market. Some high value-added special offset printing inks have also been successfully developed, meeting 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, major domestic ink manufacturers attach importance to the quality standardization and internationalization of offset ink products, and the color of some ink products has reached the Pantone color standard of the United States. Ink enterprises have passed the ISO9000 series quality management system and ISO14001 series environmental management system certification, which lays the foundation for domestic offset printing inks to participate in international market competition

at present, environmental friendly offset printing inks are also attracting more and more attention from printing users at home and abroad

II. The main gap between domestic offset printing inks and similar foreign products

although the output of offset printing inks in China has been increasing recently, the level of product quality has been improving, and the variety of ink designs and colors has been increasing day by day, there is still a large gap in the production of similar ink products between China and industrialized countries, and there are also many deficiencies in quality, which still cannot meet the needs of today's printing, packaging, publishing and printing. The main gaps are as follows:

1 There is still a certain gap between the quality level of domestic ink and the packaging level of similar products in the United States, Japan and Western European countries as long as conventional accessories are used

2. There are still gaps in printing process requirements, high-speed adaptability, product quality consistency, ink stability, etc

3. The development of special inks is in a slow state, which can not meet the printing requirements of today's rapid development of packaging and decoration, and some products are still in shortage or blank. For example: offset printing water free ink, offset printing sun resistant ink. Aromatic free offset sheet fed ink and aromatic free thermosetting offset rotary ink still need to be further developed and improved in quality

4. The application of four-color printing ink suitable for high-speed overprint in degradable polymer materials in medical devices still needs to be further improved in terms of high concentration, high transparency, brightness and excellent overprint

5. Environmental friendly offset printing ink varieties still need to be further developed

therefore, the urgent problem for domestic ink manufacturers is to constantly stabilize and improve the quality of existing products, improve product packaging, improve the quality level of raw materials for ink production, realize high quality and serialization of existing products, meet market requirements, and constantly develop new products urgently needed by the market

III. Development Trend of offset printing inks

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. Prints are growing rapidly towards colorization, and printing timeliness and quality requirements are higher. Therefore, offset printing, as an economic, efficient and flexible printing method to print high-quality prints, will still be a major printing method for a long time

as one of the raw materials of offset printing, the future development goal of offset printing ink should meet the needs of printing to be multi-color, high-speed, fast drying, pollution-free and low consumption. We should absorb and learn from foreign advanced experience, face up to the present, find out the gap, catch up, and maintain our own advantages. Through the introduction of advanced technology and equipment, it is not difficult to improve China's ink production and equipment level, technical level and product standards, improve the quality grade of offset printing ink, realize high quality and serialization of printing ink in our country, and work hard for the rapid development of China's ink industry
