Hi Rolf
Thanks for setting up the materials for this test! Based on what I am
seeing on screen, the DeviceLink does indeed produce a more faithful
conversion. I don't know if I'd say "much superior", but there is less
color shift and the tonality is smoother using the DeviceLink,
especially for the out of gamut colors. I don't know if I would see as
much a difference with a hardcopy test, but I assume there would be
some.
Of course the real question now is how did you create this devicelink
profile? As Terry mentioned earlier, "...chances are it's doing the
gamut compression the same way had you done just a simple ICC profile
conversion. There's considerable "secret sauce" in the various device
link applications..." I have a couple applications which can create
device links and they do not do as good a job as whatever you are
using. While I am inclined to believe that devicelinks are CAPABLE of
doing better conversions, I just haven't been able to make one myself!
What software did you use?
A secondary question related to your procedure: What do you mean "the
printer can match the fogra mediawedge with tight tolerances"? Tight
tolerances compared to what, FOGRA 39L? If you are using an RGB
profile and RGB images, how can you use a CMYK control strip (the
fogra mediawedge)? Forgive my ignorance if this is obvious!
Thanks again.
