There are several ways to solve the pollution problem caused by gravure printing machine.
Depending on the gravure press, the plate rolls are available in both aluminum and copper. When preparing the plate, the roll is heated in hot water and then placed in a chloric acid solution to remove the chrome layer and the rust layer. It is then rinsed clean and the iron roll is nickel plated to stabilize the copper plating and the aluminum roll is galvanized to achieve the same day. The aluminum roller is also subjected to cyanide treatment before copper plating, and the engraving process is chrome-plated and ready for proofing.
There are several ways to solve the pollution problems caused by gravure printing presses. Each method should be considered in terms of cost and resource consumption. Printers need to establish partnerships with their major source material suppliers so that suppliers can provide the technical support they need in a timely manner to ensure the quality of their products while minimizing pollution and waste. Use a shallower ink tank and improved scraper technology to reduce the amount of ink used. The steam recovery system is the largest method to reduce solvent-based contamination.
Improved methods in many devices can reduce pollution. Gravure press manufacturers use new technology for their machines and install several process improvement control accessories on their equipment. The use of vegetable oil instead of gasoline as a solvent and the use of water-based inks all reduce environmental pollution, and it is also a good idea to use a less polluting solvent to replace the current solvent.
After the gravure printing machine adopts the fully automatic cutting technology, the whole automatic cutting process only needs to place the material roll on the discharging rack, and the subsequent cutting process can complete the whole cutting action without manual participation. Taking a BOPP film with a thickness of 0.018 mm as an example, the fully automatic cutting can control the length of the remnant of the material to within 10 m. The application of fully automatic cutting technology in gravure printing machine equipment reduces the dependence of equipment on operators and improves work efficiency.
