Ah, workflow problems. I strongly believe this
is *the* real issue on today's color
management.
Double-color management, inconsistent paths,
different profiles... a
nightmare.
Ok, I cannot spot where the problem is,
but here
are some clues. Thay have been very useful to
me in past.
1) Trust nothing. Check
each driver, profile, etc. Even
if the filename and UI look is same,
maybe the
profile and driver are different.
2)
pinpoint the path. This technique is very effective
when one tries to find which profile/intent
is being applied.
ICC gives a "probe profile"
here:
http://www.color.org/probeprofile.html
This is a fake
profile that adds a huge tint, which is of
different color on depending on
intent being used.
So, just replace the output profile with this
one and do
some prints. If the workflow is configured
correctly, every
print should come with same tint color. I
guess you will
be surprised by results.
3) Isolate wrong branches. If you have a
colorimeter/spectrophotometer, print
some patches and
measure them. Isolate the parts of the
network that produces
bad results. If the workflow is complex
enough, maybe is not
worth of understanding each step. Remember,
you want good
results. A proper setup would be nice, but
you final goal are
good results.
Hope this helps
Cheers,
Marti.

Subject: [Lcms-user] Problem with Printer on
Network
Hello,
I don't know if somebody has already had
this problem.
I use a Canon IP4200 printer shared on a
Network.
When I print some color patches on it from 5 different PCs,
with EXACTLY the
same settings and same color profile, I see some
color difference on the printed results.
Any idea of how to solve this
? All the PC run on Win2K with same driver
version.
Thanks
Armindo
