At its simplest, linearization simply means putting a curve in the
print process that ensures that the printer actually produces the
requested dot percentage. An unlinearized Epson 5000 tends to block
up in the shadow regions, requiring some compensation to
differentiate between a 90% and a 100% dot.
Bruce Lindbloom has suggested some more esoteric linearization
methods, such as linearizing the luminance rather than the dot area.
Basically, the goal is to optimize the actual print performance in
terms of tonal response and gray balance before you start profiling
it.
It's possible to just profile the unlinearized printer and rely on
the profile to do the work, but it's been my experience that you'll
always get better results if you first make sure that the printer is
printing optimally. Think of it as a calibration step.
