By means of simplex-centroid experimental design, three prepolymers EB3700,6358H and 6353-1 were used to define the proportion of composite prepolymers and the performances of the samples of UV offset ink with single prepolymer and composite prepolymers such as flow curve, thixotropy crack index, curing rate, glossiness, ink transfer rate and solid density were studied. The research shows that the ink sample with the prepolymer 6358H has higher viscosity and its thixotropy crack index is higher; the ink sample with the prepolymer 6353-1 has higher glossiness; the ink sample with the prepolymer EB3700 has faster curing rate, and its proof’s solid density is higher; the ink sample with the composite prepolymers EB3700 and 6353-1 has higher ink transfer rate. By means of simplex-centroid experimental design, the best proportion of three prepolymers EB3700, 6358H and 6353-1 is1.4:1:1.
