Abstract
Image quality of print is dependent on the
paper characteristics. However, relatively
little has been studied on the imaging characteristics
of paper. In a previous report, we introduced
a new method for measuring the modulation
transfer function (MTF) of paper. In this
report, a contrast transfer function (CTF)
of print is introduced. We find that the
CTF of print, CTFprint(w), can be expressed by a simple function
of the MTF of paper, MTFpaper(w): CTFprint(w) = [1 + MTFpaper(w)]/2. The CTF of print predicted by the
function was approximately same as the measured
CTF of print.
