It would be a very mad world where different vendors used the same
reference numbers. I would go ahead and use it.

I imagine if you type in the product code of your chart with .it8 after
it, then you will find a link to its datafile somewhere on the interweb,
and probably at that context website that I linked you to last week.

Dear Sylvain
All I can do is sympathise: you are going to need to provide with more
information if you want me or others to think this through for you.
Meanwhile, I don’t know what chart you have, nor what link you used to
download the .it8, nor why you think it’s wrong.
In any case, in the first instance you might write to the people that
sold it to you.
best wishes
Michael

I imagine you will end up with something like this command:
*scanin -dipn -G1.0 -v2 input.tif it8.cht R190114.it8*
where:
input.tif - the scan you record of the colour target
it8.cht - the file from the “ref" folder of your Hugin download
R190114.it8 - the file you download from that contex link I sent
earlier

OK so the cie file is the same than the ti3 file, it is
No, it’s the input file of the chart's colour values.
The ouput file isn’t specified, it is generated with the
same name as the TIFF.
So in this case the output is a file called scanner.ti3 in
the same directory as the TIFF.
IT8 measurement data is published by the manufacturer.
Go to their web site and you should find txt files for
each batch of manufactured charts.
