Hello list!

using icclink with the -kt -l 280 options for ISOcoated.icc in and ISOuncoated.icc out does not have any effect on my conversions with a test file. I don't have a reverse lookup for the separation I'm beginning with and get rich black for my output. C=0 M=0 Y=0 K=100 leads to C=76.32 M=67.87 Y=57.39 K=83.18 when I check the conversion with icctrans of lcms. Same result in Photoshop when I convert a testfile.tiff with an applescript for color conversion using my devicelink called ISOlink4.icc which I calculated with icclink. It adds to more than 280% covering out of 100% in the beginning. So with all other rich colors of the testfile. Here's the line I wrote:

$ icclink -v -l 280 -kt ISOcoated.icc ISOuncoated.icc ISOlink4.icc

Am I wrong with it?
