Hi,
If I have some corporate logo colours that I want to match, is there a way to
do that
with Argyll?
yes.
1. Printer profile says the Pantone color is in Gamut 2. I have the Pantone
paper
swatch that I can compare with my eyes or measure with i1 pro 3. If I print
the color
on the printer I can also measure the error and the difference from the
Pantone
reference swatch
This depends on how you are able to set colors for the printer. Assuming you
can send device values (i.e. non-color managed colors to the printer, something
that in any case is necessary to be able profile it), then it is simply a
matter of
looking up the device values for the Pantone colors using the printer profile.
i.e.
xicclu -fif -ia
and enter the Pantone D50 L*a*b*.
For CMYK you might want to add a black level after that.
Send those device values to the printer, and it should
print the desired (absolute) L*a*b* values.
