I'm trying to get a grip on the technical history of the old Radius
'ColorMatch' concept.
Was the original Radius idea along the lines of an 'RGB PCS' which
physical monitors could then be brought up to using calibration, and
then from that 'RGB PCS' you had separation tables you could plug
into Pshop?
What interests me is the relationship between the actual state of the
monitor and the values used as input in the RGB to CMYK conversion.
a. Were the values the same as what the monitor was brought up to,
meaning that ColorMatch was actually a different space on each
workstation, and each workstation therefore gave you a different
CMYK, even if the CMYK table was the same on all workstations, or
b. Were the values the same as a fixed RGB which the monitor would
then approximate as well as possible, but you got the same input
values for all workstations, and if all workstations chose the same
destination, then you got the same CMYK off all nodes in the color
network ?
I know Roger was Radius product manager back then, so I've cc:ed him,
if nobody else knows.
Thanks in advance
