The relationship between paper gloss and color rendering
Paper gloss refers to the degree of specular reflection on the paper surface, expressed as a percentage. The higher the gloss of the paper, the more mirror-like the light reflected on the surface, and the brighter the appearance characteristics. In fact, in addition to the specular reflection, there is diffuse reflection on the surface of the paper, which causes the paper gloss to decrease. For paper with high gloss, the color of the printed ink is also brighter, and the visual effect of the ink is also better. It can be said that the smoother the paper, the higher the gloss and the higher the gloss of the prints. The glossiness and smoothness of paper are closely related, but the glossiness is not smoothness. The shiny surface of paper is not necessarily a smooth surface. From the perspective of the glossiness of the paper, it is of great practical significance to select suitable paper for printing according to the characteristics of the print. Such as the text of the layout of the main text of the book, should choose the general paper gloss, so as not to reflect, so that the eyes do not look tired for a long time. The printing of the plate-based layout, should use high gloss paper, so that the ink is uniform, thick, bright and pleasing.
