Drupa's Enlightenment to China's ink industry

1. the development of computer direct plate making technology will promote the progress of China's printing and ink industry

nowadays, the rapid development of computer technology has greatly promoted the progress of printing and ink industry. At the Drupa2000 exhibition, many manufacturers showed the new type of direct plate making machines with low inverter prices. Both the variety and quantity of CTP machines have increased greatly compared with the past. At present, CTP technology is applied not only in offset plate making, but also in flexo, gravure and plate making. There is no doubt that the application of computer direct plate making technology will greatly promote the reform and progress of China's printing and ink industry

2. European packaging printing ink pays attention to environmental protection

anyone who has visited Germany, Switzerland, France, Britain and other European countries can feel that European countries have placed environmental protection in a very important position while economic development. For example, Germany enacted the "packaging law" in 1998 ", in the form of national laws and regulations to ensure that the development of packaging, printing and printing ink is compatible with environmental protection. Another example is that Europe has established standardized container recycling and other strict systems in its waste recycling prevention and management, which fundamentally solves the harm of various waste substances to the environment and ensures the cleanness of the environment.

European ink manufacturers generally conduct research and formulate a series of anti pollution measures from the beginning of preparation, such as The production process, equipment design, installation, sealing, vacuum, horizontal tank and other pollution prevention measures for harmful operations of ink products have been clearly stipulated in the preparation of the factory. There are also a series of regulations on the purchase method of toxic solvents (such as benzene, xylene, etc.) used in ink production. This is worthy of our ink manufacturing industry for reference

3. The packaging printing ink color of foreign developed countries widely adopts the American Pantone standard

at drupa exhibition, we visited the booths of American flint ink company, Japanese Toyo ink company, Swiss SICPA company and Dutch Vanson ink company, and found that their ink product quality is highly standardized. Both the internal quality of products and their color standards are in strict accordance with ISO international standards. It is understood that the above ink manufacturers have passed Pantone standard rubber tensile testing machine not only in their own countries, but also in some developed countries in the world. In the process of testing, they need the following parameter certificates to occupy the publishing, printing and packaging printing ink market at home and abroad. In view of this, China should also speed up the development of Pantone color standard ink products and improve the market share

4. The rapid development of thermosetting rotary offset printing inks can be seen from the Drupa2000 exhibition that thermosetting rotary offset printing inks will form large-scale production. At the exhibition, a thermosetting rotary machine with a speed of 50000 printing per hour was exhibited. The thermosetting rotary printing ink used in this machine will have a large consumption. In order to meet the requirements of high-speed rotary offset printing machine, developing high-quality thermosetting rotary offset printing ink as soon as possible is one of the topics that ink manufacturers will develop in the future

ink and bronzing technology have become hot spots

this time, through visiting drupa exhibition and BASF in Germany and field packaging in Britain, we found that the amount of printing ink for synthetic paper (gold card paper and silver card paper) has decreased, and UV ink, UV varnish and bronzing technology have been more and more applied. German BASF company pointed out that the future trend is to take UV ink technology as the main body and face the market. Field packaging has been using UV ink in color packaging and printing since 1983 in order to reduce environmental pollution

according to the survey, the German Paper Research Institute tested the paper polished with UV varnish in the late 1980s. The results show that the paper polished with UV varnish is pollution-free after recycling. Since then, offset printing machine manufacturers such as Heidelberg and Mitsubishi have also successively produced offset printing machines with UV glazing or drying devices and separate glazing machines to meet the growing demand for UV printing and glazing in today's packaging market. More and more European ink manufacturers produce UV ink and varnish. It is reported that the UV printing series products of field packaging color printing company in the UK have accounted for 80% of all its products, because UV printing is energy-saving, pollution-free and easy to dry

in addition, in order to meet the requirements of environmental protection, some advanced European printers have adopted large-area bronzing technology, and less and less use high-cost gold and silver cards. As UV offset ink can overcome the disadvantages of slow drying of synthetic paper ink in packaging and printing, UV glazing and UV offset ink have also developed rapidly in the domestic market in recent years, such as Hangzhou HANGHUA ink Chemical Co., Ltd. and Tianjin Dongyang Ink Co., Ltd. In the future, China's ink industry should speed up the development and marketing of UV ink products

6. the development and manufacture of ink should be accelerated

in order to ensure the cleanness of the air and the health of the human body, the United States, as a developed ink industry country in the world, legislated as early as the 1980s to restrict the use of organic solvents and toxic substances in ink and their emissions in the air, and formulated a series of relevant regulations to restrict the use of polluting ink in printed matter. It is reported that the consumption of ink in the United States now accounts for 30% ~ 40% of the total consumption of ink. In particular, non-toxic soybean oil-based ink has long been used in newspaper printing. The non-toxic and pollution-free development trend of the world ink industry has affected and promoted the development of China's ink industry. It is imperative to rapidly develop and develop solvent-free ink. China should speed up the development and production of pollution-free ink (water-based gravure ink and flexographic ink) products to meet the needs of the packaging and printing industry for green packaging

7. the preparation of various spot color inks and the growing market demand

from Drupa2000, it can be seen that the preparation and production of various spot color inks are increasingly valued by ink manufacturers and printers. In recent years, the color standards for packaging and decoration printing have become increasingly standardized. The demand for spot color ink for product packaging, especially for the packaging of some famous brand products, is increasing. Ink manufacturers with strength develop or prepare spot color ink themselves. For example, American flint company and Dutch Vanson company connect the equipment for preparing spot color ink with the computer, making the preparation process of complicated spot color ink simple and easy. China's ink industry should also develop various energy storage technologies for spot color as soon as possible

8. The demand for silk ink is increasing

with the development of packaging and outdoor advertising printing industry, the market demand for silk ink is also increasing year by year. The main products are silk printing inks such as metal, paper, glass and plastic. At present, the domestic silk printing equipment has broken the backwardness of manual printing machines. Some areas have added silk printing brush machines with a high degree of automation. Therefore, the domestic demand for silk printing ink is increasing

9. the development of special inks should not be ignored

with the rapid development of packaging and decoration printing, there are more and more ink products with special needs, such as jet ink, anti-counterfeiting ink, heat transfer printing ink, heat sublimation ink, fluorescent ink, pearl ink, etc. Despite the high cost of such products, the demand is increasing. Because the special ink has a high added value, it will have a good profit
