An ink-jet printing system including at least one ink-jet ink and a means
for jetting an ink-jet ink onto a surface of a substantially
non-absorbing ink-jet ink-receiver, characterized in that the ratio
.sigma. S.sup.d/.sigma. L.sup.d of the dispersive surface energy of said
ink-receiver surface .sigma. S.sup.d over the dispersive surface energy
of said ink-jet ink .sigma. L.sup.d is greater than 0.9. A process for
ink-jet printing is also claimed. High areal throughput ink-jet printing
(e.g. >100 m.sup.2/hour) with curable inks can be performed on
different kinds of ink-receiver surfaces with a good image quality and
colour density due to a controlled spreading of the ink-drops which can
be directly cured.
