I am not aware if Translution works for laser technology as well as for inkjet so I don't know if we are talking about the same paper. I know that in inkjet terms speaking there are some differences between dye inks and pigment inks. Pigment inks dry much faster as dye inks and can end up in a sharper image where dye inks may look a little blurry in comparison therefore. Yes, FF inks may be the missing part for you.
Luis, it is always interesting to see pictures from comparison tests as you have done so feel free to post it.
Here is also a link to a possible helpful posting with pictures regarding the
black garment version of Translution.
