The DIN 53146-2000 standard specifies a test method for the determination of paper and Cardboard opacity, which is used to evaluate the light transmission performance and hiding ability of materials. Opacity is an important indicator to measure the characteristics of paper Optical inspection, which directly affects its printing adaptability and Appearance mass. The standard describes the equipment required for testing, sample preparation, test procedures, and methods for calculating the results. Through this method, it is possible to quantitatively evaluate the light scattering and absorption characteristics of paper under the conditions of backing light sources. This standard applies to various types of paper and Cardboard and is widely used in quality control and product development to ensure that the material performance meets the requirements of specific applications.
