Hello Marek,
Forget about printing in-store. You can go to different stores running the same
machine and get different results. The employees in chain stores are not colour
professionals and you can never be sure they regularly test and adjust their
machines.
I have found that submitting prints using the web service (here in Australia
several chain stores uses the same Fuji lab) gives satisfactory and reliable
results. And then if I get prints done on an Agfa machine with Kodak paper at a
pro lab, they can look slightly different again.
Finally, it's really difficult to get prints to match the a computer display.
You really need to start with a good display (sRGB gamut at least), calibrate
it to the appropriate white point, reduce the contrast ratio to match printed
material, profile it, use a colour-managed photo-viewer, view the print under
quality lighting etc.
You haven't given enough information to identify the problems in your
comparisons. And this forum is about operating argyllcms, I thought, and not
about solving general colour management problems.
I also question why people ask for advice on colorimeters and displays. Don't
they know how to use internet search engines for research? Are they too lazy to
read for themselves?
Stephen.

Subject: [argyllcms] colour management and... photo lab
Hello everybody,
I've been subscribed to this list for quite a while.
Anyway, yesterday I've done a “test” - developed (raw -> jpg) 5 photos, each
one in three versions: with Adobe RGB profile, with sRGB profile and without
profile. So resulted in 15 photos, which I had printed at Jessops in Kingston.
My expectations were as follows: photos with Adobe profile should be more or
less identical to those with sRGB embedded (as I see it that way on my screen),
photos without profile should be either printed as they were, or should have
sRGB profile assumed.
To my surprise, all photos were printed differently!
Adobe RGB prints shown right colours, but all prints were darkened.
sRGB prints shown colours as if no profile was used, photos without profile
were similarly printed to those with sRGB profile, yet still were bit different.
When processing my order at Jessops (yes, you have to do via their kiosk, they
are unable to print your prints from the CD apparently!) I've selected an
option not to correct colours etc.
So, I am lost. I've sent same test photos to photobox and a digilab pro in
London, I am still worried, that I'll get similar results...
any ideas how to get best prints from the lab? having calibrated environment at
home?
Many thanks,
Marek
