Abstract
The relation between the micro-topography of paper surface and liquid absorption in minute time was investigated on softwood and hardwood bleached sulphate sheets and an india paper by an apparatus, which was originally designed by Bristow and modified in order to be able to change the lip pressure.It was found the Parker Print-Surf roughness increased a little in case of the hardwood bleached sulphate sheet and decreased in the softwood sheet and the india paper, when the lip pressure increased. The value of Rp decreased at the clamping pressure of 10 kg/cm2 and increased at 20 kg/cm2 in all cases. The roughness index calculated from the dynamic liquid absorption decreased in both softwood and hardwood sheets with lip pressure. The distribution of depth of void on paper surface measured from the stylus type smoothness tester became wider on the softwood sheet and the india paper, but narrower in the hardwood sheet.
