%X In printing, the permeating depth formulae of power-law printing ink have been derived from the flow fluid equations for porous paper, which vary with the printing pressure and printing velocity, and the permeating depths of power-law printing ink of a few kinds of standard paper have been measured by experiment. The ratios of permeability to porosity are calculated from the measured results according to the permeating depths equations of power-law printing ink. Using the ratios and changing the printing pressure and printing velocity, the permeating depths of power-law printing ink in porous papers are calculated. The results show that computed permeating depths of power-law printing ink are in good agreement with the measured permeating depths of that. This indicates that the computing method is feasible, so that one may apply the permeating depth equations of printing ink in printing preparation and research of permeability of power-law printing ink in porous paper.
