This work aimed to solve the problems of traditional decorative base paper such as serious filler wastage, low paper strength and poor printability caused by massive filling of titanium dioxide. The experiment was based on the traditional processing technology, the filling amount of base paper in the process of paper making was reduced and the quality of the paper was improved through coating. After coating the surface of the decorative base paper, the physical properties and the printability of coated decorative base paper were tested, and the surface pore opening degree as well as the internal pore size of decorative base paper was studied adopting PDA Dynamic Penetration Characteristics Analyzer. Compared to the commercial base paper produced by the traditional process, the whiteness, evenness and tensile strength of coated decorative base paper was increased by 0.6%,33% and 340% respectively, and its roughness was decreased by 6%. In addition, the color density of dark tone, middle tone and high tone was improved by 21%,29% and 55%, respectively. When the filling weight of the coating decorative base paper was 20% and the ratio of pigments was between 50:50 and 60:40, the performances of the coated decorative base paper were significantly improved.
