Do you think that the average software user would
understand an "ISO 12647-2 Positive Acting Type 1" profile
better than a "EuroScale Coated" profile? It does have
more information (that profile really is type 1, not type
3, as I remember) but I wonder how many people know what
it means.
The concept of a device profile created by the user for the color
devices in the workflow is soaking in almost all the way through the
workflow. The concept of a device profile having a gamut of a certain
size and shape follows in the wake of that.
Photoshop has as far back as I can remember had a gamut alarm. People
are making the connection between the gamut as a 3D co-ordinate set
and the printing materials and process steps that make these
co-ordinates different.
What they cannot have is the confidence that they are targetting
printing conditions registered with the ICC and the ISO. And which if
the printing company who is their supplier should so wish, may be
downloaded as data sets to create a custom profile for the preferred
black replacement and ink limit.
It would be so very easy in the Adobe manuals to show 3D gamut
comparisons for the profiles bundled, even if it were just to
indicate that there are differences and thus help visualize what the
gamut alarms are showing within each open image.
The more common spectrophotometers become, the more common will be
the understanding that paper and pos / neg process are factors in the
gamut. Sweden prints negative, Denmark prints positive and it's been
a recurrent theme in the trade press long before spectrophotometers
became something used by people other than astrophysicists.
You cannot argue from what you think the average user doesn't know to
what Adobe should do. You need to argue from how the ICC framework
functions (e.g. rendering intents are designed to leave the user a
choice on what to do about colors which are out of gamut for the
destination space), and implement what the average user needs to know
in order to make the ICC framework work for her. Arguing from what
folks don't know and don't read doesn't help. It's arguing from what
they need to know that helps -:).
