Ink-jet printing systems and methods of use for printing visible and
invisible inks for subsequent development, which can produce text with
associated highlighting or underlining that reduces messiness inherent in
highlighting important text are disclosed. The ink-jet printing systems
and methods of use can include a substrate, visible ink-jet ink
configured to be ink-jetted onto at least a portion of the substrate to
form a first visible image, a first invisible composition configured to
be ink-jetted onto at least a portion of the substrate to form an
invisible image visibly associated with the first visible image, and a
second invisible composition configured for over-striking at least a
portion of the invisible image. The first and second invisible
compositions can be further configured to react and form a second visible
image on the substrate.
