The printing could not expect the print effect of the specific character of a printing material. Specially, a property of the paper that we are aware of the substrate has controled printability as well as run ability. The objective of this study was to measure substrate properties by measuring the water receptivity in order to know the degree of the uniformity on surface of paper. Therefore, the water receptivity was measured by fluid bridge method. And then the physical properties of samples such as ink set-off, porosity and print mottle of domestic coated papers were measured by Tappi method. Accordingly, this study obtained the outcome of water receptivity. And then we could know that the relations between water receptivity and physical properties of the paper samples have correlations. There are many measurement equipments to find out print mottle by the measurement of the reflected density at this point in time. However, it is thought that the fluid bridge method is the most proper way to find out print mottle, though there are many other ways to figure out.
