This article analyzes the mechanism of interaction between the ink and paper. The Washburn equation just based on static penetration, while in contact with the ink and paper, freedom infiltration process is a dynamic process. So it is further derived based on a model of the dynamic ink permeability of dynamic contact angle, and mathematical analyzes some of the important parameters of the dynamic model so that can strive a more accurate description of the state of penetration of ink into the paper, thereby theoretically predict the quality control of printed matter.
The paper is an applied research on the application of laser holographic anti-counterfeiting technology in the production of cigarette. Parameters in the aluminium coating process are adjusted to search the optimal production option. Data from different proofing machines are collected to find out the relationship between the thickness of the aluminum layer with its square resistance; then a curve can be drawn and the optimum conditions for the aluminum coating process is determined. Experiments showed that control of the square resistance can effectively solve the color difference in the proofing process. The study lays a foundation for stable production of cigarette packet, and provides a reference for other scholars engaged in related research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
