Buick style paper smoothness tester

Buick style paper smoothness tester, Buick style smoothness tester, paper surface smoothness tester, and paper smoothness tester are indicators for evaluating the surface roughness characteristics of paper. There are various methods in the world for measuring smoothness, such as Buick, Bentsen, and Glay, which refer to the time it takes for air to pass between paper and glass surfaces, expressed in seconds. The smoother the surface of paper, the fewer gaps between its surface and the glass surface, and the longer it takes to pass through a certain amount of air, resulting in higher smoothness.

Smoothness is related to the forming process of paper production, which depends not only on the fiber morphology and processing technology during material preparation, but also on the characteristics of the paper machine. Smoothness is divided into two types: surface smoothness and printing smoothness.

Buick style smoothness tester, paper surface smoothness tester. High smoothness paper has a high ink transfer rate in the graphic and textual parts, and the printed text on the surface of the paper is clear and eye-catching, which can achieve high-quality printing effects. On the contrary, the image is dull, the colors are not full, and the image is not clear. The commonly used paper smoothness, in descending order, is copperplate paper, offset paper, relief paper, and news paper.

To detect smoothness, a smoothness tester is used, which adopts airflow detection technology. The instrument automatically identifies the required range of the tested sample, switches the range, and accurately controls the deflation speed according to different samples to ensure that the sample is preloaded for 60 seconds according to national standards.
