My own theory is that it has to do with pre-calibration and linearity. In
both systems, BestColor and Rampage ICC, you linearize the device prior to
profiling and you can even create a specific amount of builit-in dot gain
into the device prior to printing your profiling target. That's why I think
the TC3.5 chart simply works as the device is already "behaving" properly to
start with.
The ECI2002 chart sure looks impressive to a customer but for my money I'm
probably going to go back the trusted TC3.5 target and save myself HOURS of
measuring time.
Big targets *tend* (note emphasis) to give you accuracy at the cost
of smoothness. Small targets *tend* to give you smoothness at the
cost of accuracy.
If your output process is significantly nonlinear, bigger targets
will *tend* to help. If your output is already linearized, you may
not see a significant improvement in accuracy over a smaller one, but
you may see less-smooth results from the larger than from the smaller.
So your findings wouldn't surprise me. Just be careful about drawing
any sweeping generalizations!
