Darrin <email@hidden> has me thotoughly confused here, and I
wonder if he is doing something wrong:

Darrin, ColorBlind creates output patches *independently* of your black
generation settings (total dot, max black, black start, etc.). They do
this so that you can create new profiles with different settings from
the same readings. Therefore, in theory it is impossible for your
patches to *look* different if you output them correctly.
With variations in the settings that are "reasonable" (i.e. do not
substantially limit the ability of the printer to output its full gamut)
the statistics will not vary, but it is not "unreasonable" to expect a
little variation if you start cutting deeply into the printer's
capabilities (e.g. ignore black ink). However, I am still talking about
profiles made from *one* reading of *one* set of patches.
How does your scenario differ? Have you taken new readings from the same
patches for every change in setting? (Unnecessary, and could indicate an
inaccurate measuring device.) Did you print out new patches every time?
If these turned out different every time as you suggest, there is
something seriously wrong, either with your profiling workflow or with
your printer :-)
Are you sure that each time you put out the patches (also unnecessary)
you disable all color management in the RIP and with the same (or none
whatever) linearization curves?
