Am I wrong with it?

You need to select -G to enable -kt to work. It would be safer
to select a gamut mapping mode to go with it too (e.g. -i0 ?).
Note that the command line parser will get confused if -G is the
last option before the filename, it won't know if the following
filename is the source icc or the optional source gamut file,
so make a habit of putting -g or -G near the start of the command line.


[I will see about making icclink a little smarter in automatically
selecting a mapping mode to suite the selected options in the next release. ]

O.k., I tried some more constellations with icctrans:

$ icctrans -l ISOlink4.icc
little cms ColorSpace conversion calculator - v1.8

Enter values, 'q' to quit
C (0..100)? 0
M (0..100)? 0
Y (0..100)? 0
K (0..100)? 100


$ icclink -v -l280 -G -i4 -c0 -d0 -kt ISOcoated.icc ISOuncoated.icc ISOlink4.icc
==> C=100.00 M=40.00 Y=33.33 K=100.00


$ icclink -v -g -l280 -i4 -c0 -d0 -kt ISOcoated.icc ISOuncoated.icc ISOlink4.icc
