Hi,
Please upgrade to lcms 2.2, I have checked it and it has not this issue.
On the other hand, black preservation only works on CMYK to CMYK transforms.
If what you want is RGB (0, 0, 0) mapped to CMYK black, use either perceptual
intent
or black point compensation. Anyway using -t11 would create the devicelink, but
using
relative colorimetric intent
Regards
Marti

Using the utilities, at first, I want to convert from US Web Coated (SWOP) to
sRGB and preserve black text. Meaning K=100% results in rgb(0,0,0).
My understanding is that I need to do this via DeviceLink Profile. I tried:
Linkicc -oDL_cmykToSrgb -n17 -t11 -8 usWebCoatedSwop.icc *sRGB
And this produced a file. But when I tried
Tifficc -lDL_cmyKToSrgb cmyk.tif outRGB.tif
I get the error "Couldn't link profiles"
Am I using the utilities incorrectly or am I missing some color/device-link
fundamentals (ie lack of understanding) that prevents this from working?
Any help would be much appreciated,
Andrei
