I use the print module to create jpeg files for remote (lab) printing.
I convert these images to the relevant printer/paper profile.
Now when I include those pictures in the catalog
I have no clue about the associated profile (glossy/mat paper etc).
Later if I want to reprint I must use another software
to check the profile and redirect images to the right printer/paper.
LR reads the info but doesn't display it (in metadata).
Because there's no point to reimport them.
Send them to your lab and delete the exports.
You could use the ExifMeta plugin to view the ICC profile in LR.
There is a point to reimport them.
I use LR as a DAM
and if a client wants me to send him the exact same copy of the image,
I cannot rely entirely on LR to do that (see what's happening with point curves).
That's why I want to keep the original files (same process version/identity plate).
I play safe...
Besides, this was just an example of the necessity of knowing the file profile.
I still have no answer to my question.
LR displays extensively all Exif/Iptc/etc data, but not the ICC profile !!!
PS : J.R. Ellis - thanks for the ExifMeta suggestion.
