Patent ID: 8371688

Claim:
A radiation curable inkjet printing method comprising the steps of: providing a polymeric substrate having a maximum value for Tan δ between 40° C. and 110° C.; providing a single pass inkjet printer including at least one page-wide printhead or at least one set of staggered printheads, a transporting device arranged to transport the polymeric substrate, and a curing device; jetting onto the polymeric substrate, having a surface energy S sub , a non-aqueous radiation curable inkjet liquid having a surface tension S Liq , wherein S Liq is smaller than S Sub by at least 4 mN/m; and curing the non-aqueous radiation curable inkjet liquid on the polymeric substrate at a surface temperature equal to or higher than a temperature of the maximum value for Tan δ and smaller than a melting point of the polymeric substrate; wherein the maximum value for Tan δ is determined by dynamic mechanical analysis at a temperature ramp of 3° C./min using forced oscillation with a cycle of 1 second and an amplitude of 100 μm.
