Graeme, thanks for the reply.
So - If I use COLOR_REP "iRGB_XYZ"
does that mean that my X, Y, Z values are then required, or could I include
just the R, G, B, SPEC_380, SPEC_390, ... etc.? The XYZ seems redundant to the
"primal" spectral data from which it was derived.
Thanks,
Tony
* In https://www.argyllcms.com/doc/ti3_format.html I see that I could ;
select between
COLOR_REP = iRGB_XYZ or iRGB_LAB; how do I choose?
* I presume that the data line shall contain both the {R, G, B} command
vectors that I
sent to the printer for each patch, along with the set of measurement
results that I
collected from each patch. The spectral bands seem like they would be the
most useful
of my available measurements; is there also any value added by including
my {X,Y,Z} or
{L*,a*,b*} triads as well?
* If I do need to include XYZ and/or Lab values, I'd like to try the option
of having
Argyll compute them instead of the ones that I've calculated (in case of
possible bugs
in my program). Which Argyll function is appropriate for that?
