I do get rather different figures when testing "Q60E1 rifilata.tif"
against the "DTS Q60E1 3.1 20-03-07.icc" using lprofs profilechecker:
Average dE: 3.21
max dE: 7.84
Looking at the type of faults, lprof also does show the profile
luminance being too dark by roughly 3. At least from those figures,
aging of the target and scan settings don't seem to be the cause. I
need to get some sleep now, maybe I find some more time too look at
cause tomorrow...
I email you the lprof 1.09 profile so you can check if that fixes the
problem... Lprof does report excellent mean dE 0.29 and max dE 0.92
error values for this profile.
