Water-based ink is an environmentally friendly ink that does not contain volatile organic compounds. It conforms to the development tenet of modern society and it doesn’t produce solvent volatilization and solvent residue. Therefore, it has great application prospects in the field of packaging printing where relatively strict sanitary conditions are required, however, due to slow drying speed, high energy consumption, low adhesion, etc., there are still insufficient development and application in the market. There are still some shortcomings in development and application. By searching domestic and foreign materials and literature, this paper studied various drying methods of water-based inks, and analyzed the drying efficiency of water-based inks under various drying technologies. The drying efficiency of the aqueous ink is compared under different drying techniques, and the drying methods include hot air drying, infrared drying, microwave drying, and auxiliary drying, By comparing the advantages and disadvantages of different drying methods, it provides a new idea for the efficient and energy-saving of dry water-based inks.

This papers studies a high-performance node-level service grid model, which aims to solve the problem that the current pod-level service grid model affects the service operation and consumes many computing resources. The main method of the node-level service grid model is to improve pod-accompanied service grid sidecar with the node-accompanied service grid sidecar sharing of multiple pods, combined with the cut-through of user mode protocol stack and scaling of node-level service grid sidecar. By the performance comparison of pod-level service grid model and node-level service grid, we can conclude that node-level service grid model can isolate pod services without affecting service operation, significantly reduce memory consumption without multiplying with the number of pods, and largely reduce end-to-end network delay about 30% but the overall CPU consumption as the same as that of the pod service grid model. It indicates that the node service grid model can obtain better business benefits than the pod service grid model in container cloud, cloud service providers can provide grid services for more tenants with less memory resources and network latency, and adding grid services has no impact on the operation of user applications.

LED-UV printing curing system is a new green printing curing technology for curing UV ink. Compared with the traditional UV curing device UV-LED curing device, the light source can be stabilized and ready to use without preheating, and the energy consumption is lower. It does not produce ozone and voc, and it is a green curing method. However, since a part of the energy of the LED chip is lost in the form of heat, the temperature of the PN junction is increased to lower the service life and light decay. The heat sink model was established by Solid Works and simulated analysis was performed using Fluent. A heat dissipation system for high-power LED-UV curing device was designed based on the simulation results.
