To use more precise nomenclature, the "proofing system" is composed
of two component, the proofing RIP and the proofing printer (not to
be confused with the Imagesetter RIP, which may or may not be in front of
the proofer, depending on the particular workflow chosen). The proofing
system is calibrated by the proofing RIP generating test charts,
and then reading them into the proofing RIP using a densitometer.
Any variation from expected proofing printer response is
then compensated for by the proofing RIP color correction.
(Simple concept, but it needs to be executed well if it is
to be effective.)
