The influence of paper on color

Glossiness and smoothness: the glossiness of printed matter depends on the glossiness and smoothness of paper. The surface of printing paper belongs to semi gloss surface, especially coated paper.

On color printed matter, when the light rays irradiate the paper surface at an incidence angle of 45 degrees, about 4% of the light will be reflected, which is the reflected light from the first layer surface. And the rest of the incident light through the ink layer, after the selective absorption of the ink, and then through the ink layer reflection, into the human eye, perceived by the human eye, this is the color we observed. If the glossiness and smoothness of the paper is high, the light reflected from the surface of the first layer is specular reflection, which is not easy to enter the human eye. At this time, the color observed is basically the color reflected through the ink layer.
