To understand the ink flow mechanism in mimeographing, the mechanics of fluid-saturated poroelastic solids is applied to analyze the elastic deformation of and the ink flow 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. The deformation and the accompanying ink flow are shown to be governed by four nondimensional parameters newly defined here. The numerical results show some important results ; e.g., squeezing out of the ink from the layer due to the layer compaction by the press roller plays an important role among various possible ink flow mechanisms, especially for the case where the compression duration is slightly smaller than the characteristic time of the layer.
