This is not correct. The seventh "ink" is a fixitive or primer which is
laid down prior to each drop of colored ink, in order to control the
absorbtion/dispersion characteristics. This is intended to enable the BJC
7000 to print optimally on any paper, rather than requiring specific coated
papers to do its best work. My sense, based only on this basic
understanding of how it works and not on experience, is that it would yield
little if any advantage when printing on transparency materials (no
absorbtion to control...)

I find this intriguing; do I understand you to be saying that the 7000
uses pigmented color inks? If so, it is completely unique among inkjets.
Can you verify this?
