[ppzhan Abstract] With the development of the packaging and printing industry, the ink market as the final imaging has developed rapidly. However, the ink industry will face many challenges in order to achieve further development. This article analyzes this issue.
Ink is an indispensable factor in the packaging and printing industry. For ink manufacturers, the rising price of raw materials for inks is a serious problem for them, especially for liquid inks, such as solvents and acrylic resins. As a result, the general decline in the profit of ink production has caused some ink manufacturers to remain at a loss. In the face of difficulties, in order not to affect the demand of the printing market, ink manufacturers have developed countermeasures and solutions, using their respective advantages to adjust and receive good results. First, reduce internal costs by reducing internal expenses, controlling marketing expenses and travel expenses, but mainly relying on technological advancement, developing new products, accelerating replacement, and enabling print users to have a wider range of choices. In addition, the raw material suppliers of inks are also actively cooperating to optimize the ink formulation, introduce new materials and avoid using price-increasing materials on the premise of ensuring product quality. In the face of the fast-growing global ink market, Chinese ink manufacturers should face serious challenges from both home and abroad.
Accelerate the development of environmentally friendly green ink products With the strengthening of domestic consumers' awareness of environmental protection and safety, the national safety and environmental protection regulations are gradually improved, and packaging and publishing printing inks are one of the products related to human life, and their development should also adapt to the development of society. trend. To this end, it is imperative to accelerate the development of non-toxic, non-polluting green ink products.
Further accelerate the development of water-based inks and reduce the toxic components in solvent-based inks. Although many manufacturers of water-based ink products have entered the packaging and printing market, the market share of water-based inks has been relatively small, and foreign water-based ink manufacturers have also entered the Chinese market. The authors propose the following suggestions.
Accelerate the resolution of some existing problems of domestic water-based inks, such as how to make the quality of water-based flexo inks more stable. At the same time, improve the technical content of the product, not only meet the environmental requirements of non-toxic, non-polluting, but also meet the quality standards set by the printing users.
Accelerate the solution to the problem of reducing toxic solvents in solvent-based inks, and develop towards benzene-free inks. First, try to reduce the residual amount of solvents such as benzene and xylene in the printed products, and ensure that the packaged materials such as food, cosmetics, and pharmaceuticals are not contaminated. Second, increase the intensity of the development of benzene-free inks, especially for new non-toxic products. The application test of resin in ink, although there is still a gap between the quality of benzene-free ink and benzene ink, the improvement of printability and transferability of benzene-free ink, and the reduction of sales price will be its future development. Driving force.
The development of environmentally friendly offset inks is becoming more and more environmentally conscious. Especially as the 2008 Olympic Games is coming, the demand for environmentally friendly publishing and packaging printing inks is growing rapidly. Many foreign printers are more urgently demanding environmentally friendly and harmless substances. Offset ink products, and require ink manufacturers to provide strict environmental test data, four-color offset inks that do not meet environmental requirements will be banned. At present, Tianjin Toyo Ink Co., Ltd. has developed solvent-free offset inks, thermosetting aromatic-free inks and non-aromatic soy oil ink products. Shanghai Yaying Ink Co., Ltd. has also produced environmentally friendly inks that do not contain petroleum solvents, but Still can not meet the needs of the current market for fast-growing environmental printing. To this end, it is recommended that offset ink manufacturers further accelerate the development and production of green ink products to meet the needs of modern printing.
Localization of digital printing inks Today, digital printing has become a rookie in the printing market. At present, many digital printing machines have been introduced in China, but the supply channels of digital printing inks are from digital printing machine manufacturers. They develop and produce digital printing inks that meet the characteristics of printing machine systems according to printing requirements. The world's leading ink manufacturers, such as Dainippon Ink, Flint and Sakata Ink, have developed and produced digital printing inks. Although the research on digital printing inks in China has gradually started, domestic digital printing inks are still immature and basically rely on imports. In order to meet the needs of fast printing, ensure printing quality, and improve production efficiency and efficiency, the development of digital printing ink is a top priority. Facing the fast-developing digital printing market, it is recommended that China's ink manufacturers speed up research and development, increase technology investment, produce their own digital printing ink products as soon as possible, and replace imported inks with domestic inks.
The development of UV and EB ink UV inks can achieve instant curing, free of volatile solvents, low pollution, low energy consumption, and can print materials such as metal, paper (board), aluminum foil, plastic and circuit boards. In the late 1980s and early 1990s, UV-printed iron and printing inks were introduced and put into production. In recent years, in order to adapt to the new printing field, especially in the field of packaging and printing, UV screen printing and UV softening have been developed. Ink and UV inkjet printing and other ink products. At present, the application fields of UV inks are more common, especially in the packaging and printing of products such as cigarettes, wine, beverages and medicines, and most of them use UV inks. Faced with such a huge printing market space, it is recommended to further increase the research and development and productivity of UV inks to meet market demand.
It can be cured quickly after irradiation. Since the energy of electron beam is much larger than that of ultraviolet light, the EB curing process can accelerate the curing (ie, polymerization) without using a photoinitiator. In addition, EB inks also have good resistance to rubbing, scratching and non-skinning. At present, the global demand for EB ink market has increased to 30 million to 50 million US dollars, and the development potential is huge. It is recommended that China's ink manufacturers should adapt to the needs of the fast-developing EB printing market as soon as possible, and develop and produce EB inks that are marketable.
All of the above need the support of technical talents, so cultivating technical talents is the top priority of the industry.
Technical talent training In today's fast-developing ink manufacturing industry, in order to continue to develop, we must rely on the strength of our own technology and technical talents. From the perspective of the industry as a whole, technical talents are far from sufficient, and there are different biases: First, some ink manufacturing companies regard “recipes†as the lifeblood of ink production, and only pay attention to formulas that do not pay attention to the cultivation of talents. With the "formulation" you can produce a good ink product. In fact, even if there is a ready-made formula, it should be comprehensively designed and adjusted according to market demand and printing equipment principles. Furthermore, the ink specialty belongs to fine chemicals, and each ink formulation involves many chemical preparations. Intrinsic technical factors need to be mastered; second, some ink manufacturing companies only pay attention to recruiting university graduates, while ignoring the training of their practical experience. No matter how the world develops, how the economy advances, and the technology is the best in the world, it is still a constant law.
