An evaluation of image quality for hardcopy based on the MTF of paper

Image quality of hardcopy is significantly influenced by paper properties. In this article, two kinds of image, a hardcopy and an image projected onto paper, are analyzed using a function based on the Modulation Transfer Func tion (MTF) of paper, and evaluated by observer rating experiments. As a res ult, good correlation was obtained between the function values and the obse rver rating values. It is shown experimentally that the reflectance and MTF of paper are of significant importance in the image quality of hardcopy.
