OptiCAL supports the SpectroLino, so you can do head to head testing with
that, as well as the DTP92. Clearly if the SpectroLino is supported by
OptiCAL, then the EyeOne could be as well, it being a closely related device.

One of the greatest strengths of OptiCAL is the ability to develop your own
targets for calibration, yet few users seem to be aware of how this works. As
an example, I'll describe how to use it for achieving exacting gray balance
across the entire gray range. If you run a calibration and profiling cycle,
then open an image on screen that has a grayramp of 10 or more levels, you
can open the curves window and adjust the RG&B curves seperately from 9
control points on each curve to tweak dead neutral grays at all levels.
Adjustments to the master curve can be added to readjust the brightness of
each section, if tweaks have imbalanced it. Saving the target for this
particular monitor (complete with white and black point values), and
recalibrating/profiling to that target will offer optimized grays for that
device.
