Like this for lab 50,0,0 echo 50 0 0 | xicclu -fif -ir myprinterRGB.ic If you will like to send values with an offset according to the neutral axis just do it this way. Here LAB 50,1,1 echo 50 1 1 | xicclu -fif -ir myprinterRGB.icc If you change the awk '{print $1,0,0}' part in my script to awk '{print $1,1,1}' it will send values like this: 1 1 1 4 1 1 7 1 1 10 1 1 ... and repeat for other values.
