Exactly! :-)
Device values are just that and nothing more...there's no particular
EXPECTED behavior from a set of device values.
Okay, the device values don't represent any particular device. They
are just CMYK numbers without meaning until I take measurements and
give them meaning.
Now if you were to compare your printer profile to a "reference"
profile such as AdobeRGB, sRGB, whatever, you'd have something to
compare to.
In ColorThink I could look at both profiles in 3D and see how they
match up.
Is there something else?
Would the Gamut Volume be something to base an "optimized" printer
condition on?
For that matter, the first printer profile you create could be a
basis or reference to compare against if you're going to make
further adjustments to the device such as linearization, channel ink
limits, whatever.
Using my first built printer profile as my basis for comparison almost
seems like using the colorimeter for checking itself when building a
display profile.
So lets say I have profile #1, then I decided to change the Ink
threshold for Cyan. I relinearize, print new targets and build profile
#2. In MeasureTool or ColorLab I compare the measurements of #1 to #2
and it gives me Delta E values. How do I know if profile #2 is better
or worse? Sure there will be a difference but what would I look for in
the numbers to show improvement?
Who is to say that the first attempt was flawless, its just a
characterization? After all I'm the one making VISUAL evaluations for
ink bleed, pooling, paper cockle, etc. and then setting new ink
restrictions.
Thank you very much,
