Andre,
I use a 21 step grayscale for linearizing, which gives me 21 L* or
density readings. I just copy those from the output file that Create-
ICC generates, then open the Linearization window, and use the paste
button in QTR, below the boxes. You don't need to fill all 60.
There is a line at the bottom of the output file with all the density
or L* readings in sorted order. I don't copy the entire output file,
just that one final line of data.
Should work.
