Abstract
Understanding ink flow behavior in offset printing machine is very important to optimize both its process control and material design. We have developed ink flow simulator to predict the ink film thickness anywhere on rollers, plate and blanket of the machine and on printed paper at any time. Ink film thickness is sampled every 1 square millimeter of the surface and calculated with a simple model that represents ink transfer from a rolling surface to another with a specified transfer rate, considering actual roller configuration. The result of simulation has a strong correlation to the measurement of density on corresponding actual print. Also we refer to the way of using the simulator from a point of view of a printing machine user.
