Yes, it's easy. Just open spectral data in ColorLab and then choose
Filter-Conversion-CIE Colors. Then you can select any illumination and
observer you want. Same procedure for density conversion (using different
filters).
The only problem I'm aware of is that recently Measure Tool (v. 4.1.1) is
using different internat format for spectral measurement. Previously it
was like:
BEGIN_DATA_FORMAT
SampleID SampleName nm380 nm390
and so on but now is:
BEGIN_DATA_FORMAT
SampleID SampleName SPECTRAL_NM_380 SPECTRAL_NM_390
and so on.
So simple conversion (replacing "SPECTRAL_NM" with just "nm") in text
editor is necessary before opening measurement file in ColorLab (v. 2.8).
hmmm, interesting....how about this:
66 patch (11 column x 6 row) custom target in MeasureTool v4.1.1
measured and saved spectral data both as cxf and text files. When I
try to open either in ColorLab it says 'wrong format'.
Any ideas on how to get ColorLab to recognize a custom target?
ColorLab also crashes (OSX) every time I try to compare ECI2002
i1.txt reference and sample files. Anyone else experience this type
of crash. (Haven't tried with other targets yet.)
TIA
