No, no such site exists. I imagine contex made that chart to go with their

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 the output file
isn't it ?
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.
