I think that ST is talking about direct-
inkjet printing.

This might be different to printing onto
JetStar film or good trannys that have a
gel coat.

The Copper PCB probbably does not soak up
the ink and fill in the gaps as well.

(Not that I think that direct injet is a
good idea - photo-process all the way and
save the goats)
