Abstract
A new measurement method is proposed to separately
measure the effect of ink spread and optical
dot gain on the MTF (modulation transfer
function)of printed images from an ink jet
printer.The transmittance and reflectance
of the same printed images are captured with
two different illuminations:one on the printing
surface (for measuring reflectance)and the
other through the paper base surface (for
measuring transmittance).The MTF of ink image
and MTF of print are measured from one-pixel
line printed on glossy,matte and uncoated
paper.The result shows that the paper type
significantly affects the MTF of ink image
and the MTF of print.The MTF of paper is
also measured by this method and it is shown
that optical dot gain considerably affects
the MTF of print.
