First an observation. It appears that the -xl function
in printread has a bug. In the ti3 file the resultant
values are in 0-1 scale versus 0-100 for direct XYZ
input using -xx.

You're right, this is a bug. It'll be fixed in the next release.

 I can use spectral data but I don't know what the ti3
form looks like with that included, so cannot put it
into the file by hand. It would be helpful if someone
could post an example ti3 with the spectral data
included.

The format is described in <http://www.argyllcms.com/doc/ti3_format.html>,
but of course it's a bit easier to modify an existing file. Attached
is a very minimal .ti3 file with spectral data.

I think that I can make a small utility to place the
appropriate data into a dummy ti3 from a readings file
collected by means other than printread and will
pursue that for the moment.

Take a look at profile/logo2cgats before you get too far. It's reasonably
flexible as is, and the easiest place to start if you're dealing with
a CGATS style file format.
