Good points. Totally agree. Evidently, color devices can be classified
according to their physical color synthesis type (subtractive vs additive).
And for the purposes of color management, color devives can be classified as
a function of the type of drive signals they accept. Hence, a LightJet is an
RGB device. That's from a "logical" perspective. From a "physical"
perspective, with regards to the type of color synthesis it uses
(substractive), I have to concur with your apt remarks that, like a
photographic system, a LightJet is a CMY device.
Now which is more conducive?
