China's label printing began in the late 1970s. The main technologies, equipment, processes and materials were from Japanese companies such as Fujitsu (now Lindeke), mainly in coastal cities such as Tianjin, Qingdao and Guangzhou. Gradually digest, absorb, and apply label production technology to the whole country. After decades of efforts, especially since the reform and opening up, with the development of China's national economy and the improvement of market demand, China's label industry has developed by leaps and bounds. In terms of technological innovation, it is mainly reflected in the following five technological innovations:
(1) Flexographic printing machine
In order to meet the needs of label printing, some domestic printing equipment manufacturers have developed and produced a six-color unit-type flexographic printing machine that meets the needs of label printing for many years, with a printing speed of 150m/min; some equipment manufacturers have already such as Xi'an aerospace Huayang, Shaanxi North people, Zhongshan Ostersund, etc. to produce eight-color satellite flexographic printing machine for flexible packaging printing, such as aerospace Huayang printing speed of more than 350m / min, reach 400m / min.
(2) reciprocating printing press
ZX-320 intermittent PS version trademark offset printing machine of Zhejiang Yugang Machinery Co., Ltd. won the National Key Innovation Fund Award and the Zhejiang University Science and Technology Department and Wenzhou Municipal Science and Technology Bureau for technological innovation awards. Among them, the Ministry of Science and Technology awarded 1.6 million yuan, provincial science and technology.
The hall is 500,000 yuan and the Municipal Science and Technology Bureau rewards 500,000 yuan.
(3) an ink jet digital printing machine
"Digital printing and digital printing" is the focus of China's printing industry during the "Twelfth Five-Year Plan" period. At present, the inkjet digital printing press developed by Peking University Founder, Sage Graphic, Shengde Anxun, Xinjianlong, Mengtai, Dingheng United and other enterprises has met the electronic supervision code assignment and digital printing for food and drug implementation. In terms of demand, the production speed ranges from 30 to 100 m/min. In addition, Kodak , Hewlett-Packard, Xaar, Xeikon, Singapore Jieming and other companies have also entered the Chinese label market, contributing to the promotion of digital technology in the label market.
(4) Combination printing technology
Combination printing makes complex processes simple, reducing both consumption and productivity. At present, the combination printing technology is the "Yangchun Baixue" in label printing, and it is a technology with a promising future.
(5) Development and production of flexographic plates
The 3.94mm, 2.28mm, 1.70mm series of flexographic plates independently developed by Lekai Huaguang Printing Technology Co., Ltd. have been mass-produced, filling the domestic gap.
