Printing plate making and net making technology

China's printing plate making network technology and the world are also the most changeable, fastest-moving, and technologically most advanced. In the 1950s and 1960s, China's narrow carvings and hand-operated copper barrels were the main carving tools. At that time, it was the era of planned economy. Every year, a small number of commercial personnel selected samples for production on behalf of consumers. The batch volume was very large. A pattern could produce tens of thousands of meters to more than 100,000 meters. Reducing carving did not feel that the task was urgent. In the seventies and eighties, photo engraving supplemented the reduction engraving, and the two types of plate making techniques complement each other, improving the efficiency of plate making. At the end of the 1980s, Western Europe launched a laser-engraving system, which made the process of making plate-making systems a step further. After a short period of time, it has also developed direct-smoke-making systems and inkjet-directed systems. At this time, the system-making system and CAD pattern design can quickly realize the networking operation. In the 1990s, the printing plate making technology was a huge change, and the traditional reduction sculpture was basically eliminated, even if the photo engraving was due to factors such as efficiency, cost, and environmental protection. Can not keep up with the needs of the situation, photo engraving is no longer the protagonist of the plate making system. In recent years, a series of advanced plate-making equipment for foreign countries has become self-supporting. China's printing plate-making system can be said to have entered the international advanced level.

The wax-jet netting machines developed in China, such as the SANAK Park of Zhejiang Open Source Technology Co., Ltd., and Pingwang Wax Spraying Machine, have been supplied in bulk at home and abroad, with high quality, precision, speed, and Cleaner production has a certain advantage in comprehensive comparison of various types of net making technologies. In 1997, at the networking technology exchange conference organized by Shenzhen Huawen Company, the open source company was the first to learn information on the development of wax-jet technology in foreign countries. In 1999, it also saw a European wax-netting machine in the Shanghai Pudong Free Trade Zone. The incomplete information collected was developed by itself, conquering one key technology, including many independently developed technologies. Such as circular speed. The synchronous movement of the nozzle movement and the wax injection frequency, using the optical encoder of the spindle, feeds the spindle movement information back to the main control board to adjust the print frequency and stroke of the nozzle, and the rotational speed of the garden net. Such a chain phase is used. The loop circuit completes the accurate synchronization of the three. This digital flow calculation method solves the key problem of the numerical synchronization technology and reaches the advanced level of today's international similar products. Due to the rapid development of domestic digital wax-jetting machine, it won the time to catch up with the domestic market before the foreign equipment has yet to flow into the Chinese market. It is difficult to get high prices for imported equipment and services in time, even if imported equipment. It is difficult to open the Chinese market again with lower prices. At the time of the first anniversary of China’s accession to the WTO, the domestically produced wax-jet netting machine was released early, which saved not only a lot of foreign exchange, but also boosted the ambition of our national industry.

It is a good thing for China to develop and develop a succession of internationally up-to-date technologies relatively quickly. It is a way to take advantage of “advantages of backwardness” and is a product developed by people. We have absorbed and studied assiduously and explored continuously. Some key components go on their own unique technical route. In this way, large amounts of R&D funds invested in the initial development process do not have to be invested. The R&D funds that often start are huge, so that it is both economic and time-consuming, not only in developing countries but also in developed countries. All this is a way to take this strategy. It is also a shortcut to catch up.
