Another solution: if it's hard to change Your illumination, You can take Your 
light spectrum in account and build the profile based on both illumination and 
chart spectrum data.
For example:

spotread -a -s >Illum.sp
colprof -v -iIllum.sp -oshaw Target

But most likely You have to edit *.sp file to bring it to CGATS format. See, 
for example, Office.sp in Ref Argyll directory. I don't know the other ways to 
measure and record certain illuminant spectrum.
Very likely You will not find any color cast with Your measured light. But 
likely there will be problems with other light sources if the inks are
