Did you manage to get this direct negative printing working? I always wanted this but never managed to get it right. From a 2003 (!) altphotolist.org post:
"Because the curve controls the ink laydown of each individual ink (at least in
the 4 color printers) it could theoreticaly be possible to design a
curve that inverts the image when printing. Then you only have to
edit your image and selekt the appropriate output curve (like:
negative for gum) in the print dialog. "
April 2003 Alt-Photo-Process-L: New Agfa transparancy film for inkjet
When putting an extra curve on top of the image that cuts down 255 to 254 and 0 to 1 (to be shure) I still am missing the inverted 0% field that should print 100% in a 101 field chart.
