If you mean along the neutral axis, I have the following notes on my
computer. They are based on information from this forum. My notes are
a bit old, so there may be changes.
1.creates a profile as usual.
2 People prefer a spreadsheet for this, but I like to play with the
terminal. The command will give you an idea. Xicclu is the main tool
here. If your profile is cmyk adjust the script.
$ seq 1 3 100| awk '{print $1,0,0}'| xicclu -fif -ir
myprinterRGB.icc | awk '$12!~/clip/{print $8,$9,$10}'| xicclu -ff
-ia -px myprinterRGB.icc | awk '{print
$1*100,$2*100,$3*100,$8*100,$9*100,$10*100}' > numbers
It will output like this:
5.646 2.6629 7.9493 1.7439 1.8113 1.5788
8.8071 6.1117 12.5072 2.2818 2.3699 2.0657
11.5204 8.8277 16.5375 2.9203 3.0331 2.6438
13.9005 11.0572 19.804 3.668 3.8096 3.3207
16.1926 13.0735 22.4523 4.5335 4.7086 4.1042
...
Then add the necessary number matching your ti1 file.
Typical
$seq 700 728 > pre
and put them togheter
$paste pre numbers -d " "
output
701 5.646 2.6629 7.9493 1.7439 1.8113 1.5788
702 8.8071 6.1117 12.5072 2.2818 2.3699 2.0657
703 11.5204 8.8277 16.5375 2.9203 3.0331 2.6438
704 13.9005 11.0572 19.804 3.668 3.8096 3.3207
705 16.1926 13.0735 22.4523 4.5335 4.7086 4.1042
....
Add the numbers to the first section in the ti1 file and adjust the
value "NUMBER_OF_SETS "
Build your target as usual, print and measure.
God luck.
