The GMB ColorChecker chart SG supposedly has the same colours as the
original chart in its centre section. But I've seen info suggesting
that
this is not so...
<http://www.babelcolor.com/main_level/ColorChecker.htm>
The ColorChecker SG does have a version of the original 24 patch
ColorChecker embedded in its layout in exactly the same relative
positions as the original. However, since this is a semigloss chart and
the original has a matte finish, the actual colorimetric values are
different. So you will need a new set of colorimetric reference values
if you are going to use it with any tool for the original ColorChecker.
Is it possible to use it with Tom Fors ACR calibrator script,
<http://fors.net/scripts/ACR-Calibrator/> or are the actual colours in
the
middle section too different from the original? (I don't have an
original to
compare)
You will need new values for this tool to work properly with the
ColorChecker SG.
If they are too different, what's the best way to make use of the text
file
with RGB and spectral data for the SG supplied by GMB with various Eye
One
packages to get round this? The script contains RGB values in Pro
Photo, so
some means of conversion... ??
Use a spectrometer (EyeOne, Pulse, Spectrolino, DTP-22, etc.) and a
program to convert the spectra to RGB values (MeasureTool, SpectraShop,
etc.), then replace the standard values in the reference text file with
your new RGB values for the ColorChecker SG.
