Single pass inkjet printing method

摘要

A single pass inkjet printing method including the steps of: a) providing a radiation curable inkjet ink set containing at least a first and a second radiation curable inkjet ink having a dynamic surface tension of no more than 30 mN/m measured by maximum bubble pressure tensiometry at a surface age of 50 ms and at 25°C;
b) jetting a first radiation curable inkjet ink on an ink-jet ink-receiver moving at a printing speed of at least 35 m/min.;
c) at least partially curing the first inkjet ink on the ink receiver within the range of 40 to 500 ms after the first inkjet ink landed on the ink receiver;
d) jetting a second radiation curable inkjet ink on the at least partially cured first inkjet ink; and
e) at least partially curing the second inkjet ink within the range of 40 to 500 ms after the second inkjet ink landed on the first inkjet ink. A single pass inkjet printer is also disclosed.
