Improved ink-jet printing system

摘要

An ink-jet printing assemblage comprising 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<d>/ sigma L<d> of the dispersive surface energy of said ink-receiver surface sigma S<d> over the dispersive surface energy of said ink-jet ink sigma L<d> is greater than 0.9. A process for ink-jet printing is also claimed. <??>High areal throughput ink-jet printing (e.g. >100m<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.
