Abstract: Having a calibrated monitor with an accurate ICC monitor profile is a
necessary, but not sufficient condition for an accurate soft proofing system. Soft
proofing, using a computer monitor to proof a printed piece on a conventional or
digital printing press, is an increasingly important component for remote
proofing of mission critical printed materials. Soft proofing systems are current
issues for proposed revisions of SWOP. This paper examines the requirements
for an accurate, useful and certifiable soft proofing system. The accuracy of a
monitor profile depends on both the stability of the monitor and the accuracy of
the measuring device used to build the profile. In addition to an accurate monitor
profile, the accuracy of a soft proofing system depends on the CMM (Color
Management Module) utilized, the specified white point (color temperature)
and, of course, how well the profile represents the device it is attempting to
characterize. Results of colorimetric measurements using various emissive
spectrophotometers are presented for CRT and LCD displays of controlled color
patches in RGB, CMYK and Lab modes. The accuracy of these values,
predicted from the profile versus measured, is highly dependent on the CMM
employed. Surprisingly, the accuracy of the soft proof is highly dependent on
