So imagine reconciling two CMYK profiles that one does not have a clue as to
which instrument they were measured with? Take TR-001 data that was averaged
and measured from an X-rite 938 and a Gretag SPM-100. Make those the Source
colors. Now have those colors "matched" by an output profile measured
through an X-41 or a Spectrolino. Are you saying that there is some element
of chance here? That unless the Source and Destination profiles were derived
from the same instrument, that there are bound to be irreconcilable
differences?
