According to static electricity problem in paper feeding, printing and other production processes, the method of eliminating static electricity by electrical conductivity of paper was put forward. The importance of electrical conductivity of paper on printing in good motion was discussed. Moisture content is the most important factor according to research on affecting factors on electrical conductivity of paper. The relationship between moisture content and electrical conductivity of paper was researched, and the relationship equation was found according to curve fitting. Electrical conductivity of paper is regulated by changing moisture content to eliminate static electricity of paper.
