To understand the ink transfer mechanism in mimeographing, the theory of poroelasticity is applied to analyze the ink flow through a screen/printing-master layer which is modeled by a fluid-filled poroelastic layer. The analysis shows the following : (1) some ink is sucked back from printing paper while compression by a press roller declines ; (2) the transfered ink mass is its maximum if the duration of compression is nearly equal to the characteristic time of the layer ; (3)the ink flux and transfered mass can be appropriately estimated by using the effective permeability and elastic modulus defined ; and (4) compaction of the poroelastic layer by the press roller squeezes out ink, which plays a predominant role in the ink transfer.
