Abstract

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 σ Sd/σ Ld of the dispersive surface energy of said ink-receiver surface σ Sd over the dispersive surface energy of said ink-jet ink σ Ld is greater than 0.9. A process for ink-jet printing is also claimed. High areal throughput ink-jet printing (e.g. >100 m2/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.
