1. The biggest material loss in the process of gravure printing production is the waste produced by the start-up debugging and overprint inaccuracy. If the fine adjustment operation is closely linked with the process steps, a stable and predictable waste value can be obtained. The domestic gravure printing equipment manufacturing enterprises adopt the latest technologies such as fast pre registration and high-precision tension control, which make the cutting loss, equipment restart loss (registered), order change loss, order loss before restart and speed reduction loss reach a very low level, even better than the international advanced level in some aspects. Under the pressure of low profit of flexible packaging products, domestic gravure printing enterprises pay more and more attention to the material consumption index in the process of printing or composite equipment processing (including normal roll change) when selecting equipment, in order to reduce the product cost to the greatest extent. Therefore, material loss data has become an important index for flexible packaging gravure enterprises to select equipment. Today, the advanced gravure press operation time is greatly reduced. The integrated car of upper plate and inking realizes the integrated operation of upper plate, transport plate and inking, and can clean the plate roller and ink groove offline; through the fast inking system, the solvent is directly supplied to the ink tray from the solvent room, and the input quantity is directly controlled by the ink viscosity controller; the sleeve pressing roller technology does not need to replace the tooling, so the labor intensity is reduced, and the replacement time is greatly shortened; the rapid replacement of scraper technology realizes scraping It can quickly replace the knife; the laser edge system and the quick clamping system of the safety chuck realize the fast rolling up and down; the fault display and alarm help the maintenance personnel to quickly diagnose and repair; the historical fault alarm indication can reduce the maintenance personnel's troubleshooting time. In gravure printing production process, the energy consumption of drying oven accounts for a large proportion. The application of heat pump technology, waste heat recovery system and layered oven can effectively reduce the consumption of heat energy. The automatic monitoring and drying system based on LEL can not only save energy and reduce emission, but also prevent the risk of explosion and combustion in the drying system, and greatly reduce the cost of tail gas treatment. 2. There are three main ways to control the VOC emission of gravure printing, which are source control, process management and end treatment. Source control is to reduce the use of organic solvents from the beginning of printing process, so as to achieve the purpose of VOC emission reduction. The main measures are to promote low VOC or VOC free environmental protection ink, cleaning agent and other raw and auxiliary materials, such as the promotion of water-based ink, single solvent ink, etc. 3. Non benzolization of gravure ink and the application of integrated ink. With the concept of environmental protection and sustainable development becoming more and more popular, the relevant national environmental protection policies have changed from the stage of "having laws to abide by" to the stage of strict law enforcement, and the requirements of terminal enterprises for environmental protection are also higher and higher. Therefore, the benzene free process of gravure printing industry in flexible packaging will be accelerated.From benzene containing ink to benzene free ink and flexible packaging gravure printing industry is a major technological progress, but also another innovation of environmental protection technology in ink industry. Industry backbone enterprises and some small and medium-sized enterprises have begun to use benzene free ink. But for small enterprises, it is still mainly containing benzene (toluene, xylene) ink, urgently need to be standardized. At present, the integrated ink has been widely used in some large-scale flexible packaging gravure printing enterprises, which will become an important development direction of gravure printing ink.
