Kevin,
I also have had the same experience
as. If you gray balance and properly linearize an inkjet device it will
help decrease the delta e in the long run. It seems to take some of the
guess work out of the process. This problem has been alleviated somewhat
by the use of iterative color matching but in non-iterative processes these
techniques can help.
Regards

Yes, I've heard that a 'good profile' will be able to handle a
non-neutral linerization/ink limit. However, I have found that a
profile can only go so far in correcting this problem. I have developed
a habit of visually neutralizing at the linerization/ink limit stage
before I continue on to creating a profile. Please bear with me as I
explain. If we consider how many colors the human eye can see (let's
just say there are several million for now) and if we consider how many
color patches an ICC profiling package reads (the maximum in Monaco is
2989 patches) then you can understand that there is a huge amount of
'interpolation' between what the profiling software reads and what the
human eye can see. In other words, from and extremely limited number of
colors, the profiling package must 'guess' exactly how millions of
colors will be created. The only way a profiling package can do this
with any degree of accuracy is if it is fed data from a 'linerized'
printer - or a printer than can print fairly close to neutral through
linerization and ink limiting. I know I will be 'pinged' on this
assertion, so I'll hold further explanation for the future.
