The work aims to propose a testing and evaluation method for rubber blanket printability based on the printing quality parameter, in order to control the printing quality and improve the rubber blanket quality. Under the same test condition, the imported offset blankets (A, B, C) and domestic offset blankets (D, E, F) were used for printing. The printing density, trapping, color difference, dot gain, over bearer and other parameters were tested. As a result, all blankets’ mean standard deviation of KCMY density was about 0.021, and the RGB mean trapping was around 92%. The KCMY mean color difference of blankets A and C was greater than 5, and that of the remaining blankets was around 4.78. The 50% KCMY mean dot gain of blanket B was 7% at the dot area, and that of the remaining blankets was 9.7% or so. The thickness reduction of blankets A, B and C were around 0.02 mm, and that of the remaining blankets was about 0.05 mm. In conclusion, the ink transfer performance and dot reducibility of domestic and imported blankets are good, the M and Y color reducibility of blankets A and C is poor, and the resilience of blankets D, E and F is poor.
