To understand the ink How mechanism in mimeographing, the mechanics of fluid-saturated poroelastic solids is applied to analyze the elastic deformation of and the ink How through a screen/printing-master layer which is pressed from below by a press roller and subjected from above to hydrodynamic lubrication pressure induced between a printing drum and an ink roller by rotation. Special attention is placed on how the elastic nonlinearity, found in our experiment, of the layer affects the ink flow through it. The numerical calculation has shown that the nonlinearity influences to some extent on the ink out-flux history and to a greater extent on the ink volume transferred to a printing paper sheet; however, the conclusions obtained in the previous paper where the linear elasticity was assumed do not need to be changed.
