This way we reach a TIC in neutral black that is 233%

Note: This technology do not set the TIC limit to 233 for all colours, it
is indvidual. A dark red can for example end up 244%. Normal ICC-profiles
are in other words a compromise: the TIC will limit all colours to one top
value for TIC.
One more example: for newsprint we have reached a TIC, for neutral black,
around 180% with a better L-value then ISOnewspaper26v4 - but a dark red
can in the same print reach 209%.
And so on.
Nice figures but it's good to know how the CMYK combinations were created.
Maximum K of 100%? "Dark Red" in newsprint 244% with still cyan in it
instead of K?
Or in other words how long and how wide are the GCR settings for these
profiles?
