Hi Michael,
I learnt a lot from your mail - thanks very much.

in what way would this hit my output? Would colors be completely off,
looking weird, would I lose detail, would images be biased toward certain
a color, would they become too dark or too light,....
Or asking in a simplistic way: how badly would I be hurt by this problem?
Also: given I stay alerted, and I am a printng house and receive color
managed files from many places. If I am lucky, I could find out that all
profiles in job A have been created by a tool from vendor X, and all
profiles in job B have been created by a tool from vendor Y. If I had a
set of printer profiles for my presses done with tool X and another set
created with tool Y - would this put me in a better position (given I'd
use the resp. profiles for my conversions)? (A similar question could be
asked for production stages further up the production chain.)
And: Is there any knowledge/experience around in the industry like
"Profiles from vendor A exaggerate a certain aspect, discard info about
yet another aspect and calculate all dark colors in this special way", or
maybe insights like "Profiles from vendor B are very strong when it comes
to outdoor photos but they don't handle still lives or textiles very
well" etc., so that one could at least have some clue in what way
profiles from different vendors differ. Also - maybe this is simply
crazy, but asking such questions helps me clarify things for myself -
wouldn't it be possible to create converters that convert a profile from
vendor 'A' to a profile from vendor 'B'?
