We have made some experiments on whiteness, smoothness as well as opacity.<BR>Whiteness is remarkably less in Japanese paper than in foreign-style paper.<BR>Japanese paper, when utilized to coloured paper, demands particular deliberation upon its whiteness.<BR>Smoothness is important in case of printing : but the weak-point is that smoothness differs between one surface and the reverse.<BR>Opacity relates to closeness ; the denser the closeness is, the bigger the opacity becomes.<BR>Japanese paper, on the whole has a small opacity.
