Simulation the Effects of Vibrator Oscillation of Offset Printing

The relationship between stroke length of vibrator roller,different ink zone and ink distribution in the process of ink transfer was analyzed by the way of computer simulation with the inking system of Heidelberg SpeedmMaster Offset Printing as example.The result showed that the retained ink has a linear decrease as the increase of stroke length,and ink in one zone can flow to the adjacent zone by normal distribution;the distribution of two ends ink zone have different behavior with each other.
