Ok. I'll run an example using 1.1.0. colprof -kp 0 .1 1 .98 .5 -l300 -L98 FOGRA39L icclu -ir -fb FOGRA39L.icm From -kp stpo=.1 I expect 90 0 0 [Lab] -> K~0-1% and get: 90 0 0 90.000000 0.000000 0.000000 [Lab] -> Lut -> 0.102880 0.074649 0.080666 0.034677 [CMYK] K=3.47%, too much. Trying 98 0 0 [Lab]: 98 0 0 98.000000 0.000000 0.000000 [Lab] -> Lut -> 0.020894 0.015157 0.016418 0.005429 [CMYK] K=0.54%, transition already started. From -kp stpo I guess I would like it to start where I expect it to ;-) Having -kp enpo=1 and enle=.98 (shape=.5) I expect a continuous concave curve up to K~98% where it ends. Instead the curve bends just before ending. To me, this bend before the end is not consistent with -kp enpo=1. Output from xicclu -g -ir -fb FOGRA39L.icm is attached. > Another aspect not covered by the current control is exactly how the > black is determined away from the neutral axis.

"Wide" is definitely what most people want "out-of-the-box" I guess. Martin Weberg
