As an environmental printing method, UV inkjet printing is becoming a hot research topic and has great prospects for development. The purpose of this paper was to integrate theory with practice to analyze the relationship between printing paper and UV inkjet printing quality. This could make press worker determinate rationally printing paper and improve the printing quality. In this paper, kinds of paper surface characteristic (including whiteness, glossiness, roughness, Permeability, absorbent) were measured. Printing tone and color reproduction results of these papers were experimented. Different prints parameters were tested with saturation, hue error, gray scale and coloration efficiency. Data of the paper parameters and prints parameters were calculated separately by Principal Components Analysis (PCA) with software. Then, the equation between paper parameters and paper quality synthetic value was obtained on the basis of the tested data. The equation between prints parameters and prints quality synthetic value was obtained in the same way. Linear regression was used to find the correlation between line combination of print quality synthetic value(y-axis) and paper quality synthetic value(x-axis). Paper printability prediction equation is derived according to the curve. It was shown that the results can provide valuable reference for the evaluation of the quality of printing papers and improving color reproduction, and can be used as one of the basis to guide the production.
