Effect of whiteness
The whiteness of paper is essentially the degree of reflection of visible light on the surface of the paper and can be expressed as a percentage.
The whiteness of paper is the basis for the vividness of prints. Although completely pure white paper does not exist, if you can approach pure white paper that can reflect almost all visible light, the color characteristics of the ink can be fully utilized; if the paper is color-tinged, it is often bluish due to the raw materials of the paper. It may be yellowish or grayish. Such paper cannot reflect light of various wavelength bands in equal proportions, or it cannot reflect all colors. Therefore, the use of color-shifted, partially-gray paper for printing can affect the hue, lightness, and saturation of the print.
The degree of whiteness of the paper directly affects the contrast of the printed matter and the reproducibility of the image. In general, a high degree of whiteness will result in a darker ink, a higher level of gradation and sharpness in the picture, a clearer color in printed images, and a stronger contrast in tone levels. On the contrary, the whiteness of the paper is poor, and the tone and color gradation of printed images are also gray.
Effect of paper efficiency
The paper surface efficiency of paper is essentially the combined effect of paper glossiness and absorbency. The surface state and ink absorption of the paper will simultaneously affect and change the hue and gradation of the ink of the three primary colors, which in turn will cause changes in the color tone of the color mixing ink and affect color reproduction. However, different papers, both of which vary in performance, are printed using the same ink, and their color reproduction is sometimes very different, sometimes it looks essentially the same.
