Hi, I tried the following:
v1.1.1/Vista
PSO_LWC_Improved_eci.icc -> extractttag -> txt2ti3 -> colprof -l300
-L98 -kx -qm pso_lwc_improved
icclu -s 100 -fb pso_lwc_improved.icm
10.000000 0.000000 0.000000 [Lab] -> Lut -> 78.447630 69.659610
59.898836 90.575497 [CMYK]
5.000000 0.000000 0.000000 [Lab] -> Lut -> 78.565049 69.875403
60.700611 90.428310 [CMYK]
0.000000 0.000000 0.000000 [Lab] -> Lut -> 77.896560 66.694280
62.661979 88.768232 [CMYK]
I can't reproduce the yellowish shadows. What is your complete commands?
