Hope I've got this right : (1) The first part of the post suggests that
there is no right or wrong approach to reassigning profiles, if it is
known that the wrong profile was assigned. (2) The second part of the
post suggests a method whereby it might be known if the right profile
was assigned in the first place. (3) The objection from Roger is that
mis-assignment is associated with older software and with software
where CIE-based color management is switched off, so it comes down to
users failing to upgrade software or failing to operate software
correctly. Adding a metadata level won't remedy either of the two
obstacles in item (3) IMHO.
Basically, once one moves beyond color managing loose images, one moves
into PDF which brings into play the full imaging model. To understand
this imaging model to a level where one can guess what a button like
"Emit passthrough PostScript" implies is a major investment in time and
energy. Just as the ColorSync community needs to step from raster
drivers and loose images into the world of complete pages, the PDF
community needs to step from the complex level of communication in
which the imaging model is cast.
The lever is economic self-interest. PDF has to become sufficiently
interesting for the creative community that it will merit the attention
HTML has commanded for the past several years. Most any professional
photographer has an HTML website and an HTML authoring application, but
how many professional photographers have Adobe InDesign, Acrobat
Professional and an Adobe PostScript 3 RIP with support for in-RIP
separations and 2-byte fonts (how many even know what a 2-byte font
is?).
Adobe has added capabilities to InDesign 3 which may begin to shift the
perception of PDF from a highly technical means to reach a press
(through Distiller which is strictly for true techies), to a broadly
useful format for RGB projects intended both for screen and print
delivery. Moving color management from a niche technology appreciated
by two per cent of the user base to a mainstream technology appreciated
by a quarter of the user base revolves around such developments outside
ICC color management IMHO -:).
Thanks,
Henrik
