As for editing, more than once I've found profile editing programs ruin
the black generation or the ink limits. So my personal favorite method
for editing is editing the instrument values before building the profile.
The visual way to do this, very unorthodox, has been to make a TIFF image
of the Lab readings of the original chart (via Logo ColorLab). Then open
it in Photoshop, and place some Lab photos at the side. Then edit in
Photoshop, slightly, to get desired visual appearance (calibrated monitor
needed). Then crop the edited testchart, downsample it so that each patch
is only one pixel, and save as RAW. A linux shell line converts that raw
into tab delimited ascii values, which go to excel, and are saved into a
testchart ascii file.
That one is imported into PrintOpen, and the profile made. That way I
have a first-generation profile, concordant with PrintOpen's internal
model, but in fact edited.
They really do take their coffee strong and black in Peru -:).
