JIS P8119). This shows that when a rubber elastic body is used to press a sample f 1 kg/cA on the surface of an 11c4 mirror glass disk with a 1 cl vent hole in the center, and the vent hole is maintained at 300 mm Hg, the sample surface and Smoothness is expressed by the number of seconds it takes for 10CG of air to pass between the glass surfaces. This measurement result is meaningful as an index representing the function when used between a rigid body such as paper or various sheet glass and an elastic body such as rubber. However, when paper or various sheets are used between rigid bodies, no correspondence is observed in Bekk smoothness.

の通過秒数を測定するものである。Structure of the Invention In order to achieve the above object, the present invention is characterized in that the smoothness of paper and various sheets is measured by the following method. That is, instead of the rubber elastic body for suppressing the sample described in the conventional example, a rigid body, for example, a mirror surface with a diameter of about 40 mm and a lath plate, is used to measure the number of seconds in which air passes.

に設定する。The mirror glass plate used here is not limited in material or shape as long as it is a rigid plane with gas-shielding properties. ! ! A glass plate with ventilation holes only needs to have holes that allow gas to pass through.
There is no limit to the number or shape of holes. The parallelism of the pair of parallel planes formed by these two rigid surfaces is such that it follows the sample and is not fixed. Further, the area of the plane may be arbitrarily standardized, and is generally 1, for example, 10 cl. The pressure of the gas through hole affects the number of seconds and is generally 300mmH9.

Place a sheet of paper and place a mirror finish on it at 37, f/5m.

これら第２〜３図から明らかなように、本願発明の方法
の値とべ、り値とはほとんど相関がなくベック平滑度で
剛体間に利用するシートの評価ができない事がわかる。As is clear from these FIGS. 2 and 3, there is almost no correlation between the value of the method of the present invention and the stickiness value, and it is understood that the Bekk smoothness cannot be used to evaluate the sheet used between rigid bodies.

る場合は意味がない。The higher the uniformity evaluated using the present invention, the less uneven the sheet. The synthetic paper shown at 1 in FIG. 3 is a very uniform sheet. On the other hand, the glassine paper shown in Fig. 2 11 has a uniform density due to calendering, but the original unevenness in papermaking causes thickness unevenness, so the uniformity is 0.04''! It is meaningless when used between rigid bodies.

Prepare thermal paper. When this thermal paper was wound around a smooth aluminum drum and recorded with a line-type thermal head, the higher the smoothness of the present invention, the better the image was obtained without unevenness.
