David,
It is a fact that all ICC profiles are not created "equal", from the same
characterization data. They should match closely on the CMYK to Lab
direction but not necessarily on the Lab to CMYK (or Lab to RGB) direction.
So that is one important difference. It does not mean that something is very
wrong with profile construction, it means all profilers are obviously
subject to different "rules".
Now the case I'm after is when two conditions appear different to my eyes,
either because of illumination or because of physical differences in the
colorants. It's possible that colors don't match because of my deviation
from the standard observer but that's an hypothesis I must rule out at the
onset. I've long took the Munsell-Farnsworth 100 Hue test but that's not a
guarantee of anything, in my experience. I've seen pressmen take the test
and yet, they still see colors differently than me...
Why I need to edit profiles then? I could well "hide" behind the numbers and
leave it at that. Suppose my proof visibly appears "reddish" overall,
compared, say, to my press sheet, despite being well within some published
tolerance. That's entirely possible, because of instruments idiosyncrasies
or what not. Suppose I'm not happy with the status quo and have the nerve to
pretend I could improve things, visually, through some kind of profile
editing. That is one case where it would be useful to coerce colors one way
with a profile editor or through built-in editing tools of a proofing RIP.
Of course, doing so may have unwanted side effects but that's something I'm
willing to live with, it's a choice I consciously make.
Best / Roger

Well, I was taught, trained, had drilled into my brain, if the custom icc
printer profile was not good, do not tweak it, but create another custom
.icc profile.
I don't know where that stands with any one else.
I create my own custom .icc profiles for my NEC PA271w, about every three
(3) days. And create my own custom .icc profile for my Epson Pro 9900.
I also do this service for my clients.
Sure, I have looked at some canned profiles. Tried one. In my humble
opinion, there is nothing like my own home grown .icc profiles I have
complete
confidence in.
I remember in my early days, (OS 8.6) there was a "what you see is what you
get" by some software vender. Don't remember the name. It included a
profile
editor that was simple to use. Then I get the Datacolor, with Spyder, or
whatever the name is/was, the master edition, and it included a complicated
profile editor. Never ever
did learn to use it. Still have this master suite and Spyder. Threw out
the suction cups that came with it. Don't use it. Anyone want it?
But here is what really challenged me in those days of OS 8.6. Different
software providers' programs never gave the same profile, for the printer,
monitor, or scanner. The worst offender in my experience was the Spyder
stuff.
Being way too naive, I had the illusion all programs would give the exact
same results. Wrong! ! !
I currently use i1Profile and i1spectrophotometer. I don't want to get
messed up with other software programs. Even as I write this, I have tried
i1Profiler with my NEC PA271w, as well as the SpectraView II software. I
just don't know if there is a difference in the profiles. However I do
keep using the SpectraView II software for the NEC. An NEC technician
told me, after I had purchase the SpectraView II software, not to purchase
their
software if I already have the i1Profiler.
So, if someone is unhappy with the canned .icc profile, I would suggest
using a custom profiling service.
