But with frescos, the 'ground' pigments are enormous as compared to the inkjet ground pigments, so, perhaps,
the 'rules' in regard to the calcium carbonate and inkjet stability are different due to the greater surface
area vs. particle mass of these extra-fine inkjet pigments.  On the other hand, I could be completely wrong.

I'll try and go through that section of the:  'Stability Issues and Test Methods for Ink Jet Materials,
Barbara Vogt, Department of Image Engineering, University of Applied Science, Cologne' paper.
