Is that a Pantone green or RGB?
Could someone provide a simple explanation (or a link) for the
difference between calibration & linearization? I originally thought
that if you calibrated a device (i.e., printer) then some type of
linearization would be calculated?
Mmmm, no. Two different operations.
Calibration is making a device (your choice) conform to a known state
or performance level.
Linearization involves first measuring to what degree a given device's
output deviates from the value(s) input, then somehow creating &
applying a correction to its behavior so what is input is also output.
Once calibration is achieved, linearization can be adversely affected
by many independent variables.
Characterization - often referred to as profiling - is yet a different
(but not unrelated) process whereby a given device's performance is
measured, while it's in a known state, so that it's expected behavior
can be applied within the intended workflow.
