Abstract
Ink penetration behaviour into paper stocks at various sizing levels' was investigated. In the unsized paper, ink penetration can be predict ed by the Lucas-Washburn equation. However, with proceeding sizing the penetration speed decreases and the ink gets to an equilibrium penetr ation depth, and the data deviate from the Lucas-Washburn's equation. This phenomenon can be explained by scalar concepts. The ink penetrati on depth chi(p) near a percolation threshold pc can be predicted by th e bond percolation theory as chi(p) is similar to (pc - p)-1.
