Finished Paper Glossiness

Paper glossiness is used to represent a kind of surface optical properties of the paper, which reflects the finished paper glossiness quality and print quality. In a sense glossiness is a very important quality indicator in paper making process, it determines the beauty of the prints.

Paper Glossiness Influencing Factors

The determinant factor of paper glossiness is paper smoothness. The paper is uneven, it will reflect the light into various angles, and the paper glossiness is low. The more smooth paper, the diffusion ratio of the light reflection is smaller, the higher the paper glossiness. After the paper is coated, the fine particles of the paint fill the surface of the base paper, so that the paper smoothness is improved, and the glossiness is naturally improved. But in fact, only by the coating, also can not greatly improve the paper glossiness, only after a super calendering, so that the paper is passed a strong friction, the glossiness will be improved by leaps and bounds. This is because after the coating the paper surface smoothness has greatly improved, but the surface small bump also not achieve optical smooth, there is still a lot of light diffusion reflection. After super-calendering, the small bump of paper surface further reduce, the glossiness also followed by a sharp rise.
