Does it mean that I shouldn't use -nc option in colprof if I want to set the
total ink limit in collink?
What does the total ink limit parameter mean for colprof when the calibration
curves are provided? For example I have the calibration with limits detected by
printcal C=79% M=68% Y=48% K=52%. If all channels is at their maximums, will
the summ be account in colprof/collink as 247% or 400%?
