The development status and development trend of printing technology in China

2. Development status of printing technology

After years of development, China's printing technology has been innovative development, from 2006 to 2011 the world's top 12 printing market chart, China has replaced Germany and the United Kingdom to become the third largest printing market. However, with the development of technological innovation and change, there is still a big gap in the development of printing technology in China compared with advanced foreign countries:

2.1 Achievements of printing technology in China

The printing industry in our country has a long historical development, so our printing technology is relatively mature, our printing technology has made good achievements: first of all, our digital printing technology is more and more perfect. Digital printing is actually through the computer through the printing device, directly online printing an emerging printing process, with the continuous development and progress of digital technology, digital printing has been a simple color printer, to the direction of digital special printing press, printing materials are also from the special printing paper to the direction of packaging printing materials change. The printing format has developed from the traditional small size to the large format direction, so as to better avoid the error between the proofing and printing different processes, so that the level of packaging printing technology has also been better improved. For example, 3D printing technology is now widely used (see Figure 1); Secondly, the performance of printing equipment is becoming more and more perfect. Taking semi-automated and automated equipment as an example, we developed a digital indentation machine in 2009, and in the next two years, its total sales in the domestic market is not more than 10, and in 2011 sales have more than 50, and then sales are doubling every year. Finally printing technology integration technology application. D ICO w eb on-board plate-making commercial rotary machine features: repeated printing without a plate image imaging: modular design, can be diversified combination: simple replacement of drum sleeve and drum. You can print a range of different sizes and products. Advantages: The concept of operation is simple and requires few hands. Integrated digital prepress process.

2.2 The defects of printing technology in China

(1) China's printing technology has not achieved green. Taking gravure printing as an example, gravure printing occupies a dominant position in packaging printing. Due to its wide range of substrates, high quality and high technical content, it is widely used in packaging printing of food, medicine, tobacco, wine and other industries, and combined with a number of special processes, it is widely used in the printing of securities such as anti-counterfeiting trademarks, banknotes, stamps, etc. Products and people's lives are inseparable, gravure shows a strong vitality. However, the emissions of VOCs in gravure printing seriously pollute the environment, and it is necessary to put forward technical problems and actively propose solutions from the aspects of the water-based printing ink and adhesive at the source, the production and manufacturing of plate materials, the process control in printing production, the transformation of gravure equipment, and the integration of recycling devices in the end treatment.

(2) The product performance structure is unreasonable. Throughout the overall status of China's printing equipment, there is a lack of high-end equipment, low-end equipment surplus problem, this situation can only cause the printing industry results unreasonable phenomenon, seriously affect the healthy development of the printing industry. (3) The application level of hybrid printing technology is not high. Hybrid printing technology is one of the trends of the future development of printing technology, foreign advanced countries of hybrid printing technology has been very mature, but China's hybrid printing technology is not mature, especially the lack of a complete printing digital production chain. In addition, China's relevant talents are also insufficient, and the lack of talents will directly lead to the development of printing enterprises. However, the talents cultivated by the current vocational colleges can not meet such needs. Therefore, it is necessary for the state, higher vocational colleges and enterprises to jointly establish a sharing mechanism to meet the requirements of talents in this area.

3 The development trend of printing technology in China

Based on the rapid development of China's Internet technology and the requirements of the "13th Five-Year" development plan of the printing and packaging industry, combined with the current development status of printing technology at home and abroad, the development trend of China's printing technology mainly shows the following trends:

3.1 Highly automated

Automation is a concrete embodiment of the integration of the "Internet +" strategy, with the development of computer technology, many new printing equipment has been equipped with automatic processing technology, such as computer automatic technology control, shaftless technology and optical fiber transmission technology. Traditional printing workshop due to the principle of printing paper material problems in the printing process due to environmental humidity factors, resulting in printing work is affected, so the application of dehumidifier printing plant has high application value, to achieve automatic control of the plant temperature, when the humidity and temperature in the plant exceed the predetermined temperature, The device will automatically stop, and when the actual humidity is lower than the predetermined device, the device will automatically turn on, realizing the automatic control of the printing process. The application of this equipment greatly improves the economic and social benefits of printing enterprises.
