Why is my white space printing yellow? i1Pro, ArgyllCMS, PrintFab Composer used

[mattbuilt1]

I am printing dye sublimation inks in an Epson T5270 using PrintFab Composer as my RIP software. My color profiles are created using @Emulator 's CAP957greys335.txt batch file to create targets. These targets are printed using PrintFab Composer with no profile and sublimated onto a polyester film. Whites are white on the no-profile sublimated target. Scanning is done with an i1Pro Rev D no-cut. The generated profile has these flags: colprof -v -qh -i D50 -o 1931_2 -S AdobeRGB1998.icc -cmt -dpp -D. Finally, I print from PrintFab Composer with the new profile selected and an intent of either Perceptual or Relative Colorimetric with visually identical results - a very yellow tint to all white areas. If I choose Absolute Colorimetric the yellow effect is significantly worse (not surprising). The AI answer is that this is due to whitepoint compensation so I have been trying to understand if my profile is compensating for fluorescent whiteners or optical brighteners. I ran profcheck and all 8 of my pure white patches have a low Delta E (ave 0.6). However, I don't really understand what profcheck is doing. If the culprit is OBAs or FWAs, wouldn't the error be between my .ti1 and .ti3 files, not between .ti3 and .icm? The command I ran was: profcheck -v2 -s *.ti3 *.icm. I would greatly appreciate any insight; feeling in over my head with this.

I'm not clear why you are trying to print with the absolute colorimetric rendering intent; you are not doing any proof/soft proof type action under a specific environmental light condition to emulate a target paper on a proof paper. Since I'mnot using ArgyllCMS I cannot comment any further on questions around profiling.

I appreciate the response. I am not trying to use absolute colorimetric. I only included in my print samples to get an idea of the range of whitepoint adjusting that the profile would produce. My objective is to print from our RIP software with zero whitepoint compensation which I believe produces the yellow effect.
