Ink film coat weight was measured using an internal tracer method. Commercial toluene based gravure inks were marked with the tracer, which can be detected analytically and used to calculate ink film coat weight. The ink film coat weight versus relative print density data was plotted and curve fitting was performed using six previous proposed models. The models that were used to fit laboratory results were also found useful for pilot plant press results. Oittinen model and Calabro-Savagnone model fitted the experimental data better than the other four models, measured by the sum of the square of residuals and their distribution around zero point. These two models were used to study ink mileage characteristics. Permeability and pore size were found to have more effects on regression coefficients derived from curve fitting than roughness. Ink requirement of black ink is much less than those of cyan and magenta inks. Magenta ink had higher ink mileage than cyan ink except at very low coat weight.
