Abstract
A radiation curable inkjet printing method for producing printed flexible foils and plastic bags wherein a web-like polymeric substrate having a maximum value for Tan δ between 40° C. and 110° C. and a surface energy Ssub is printed upon using a single pass inkjet printer with a non-aqueous radiation curable inkjet liquid having a surface tension SLiq, wherein SLiq is smaller than Ssub by at least 4 mN/m, and curing the radiation curable liquid on the substrate at a surface temperature equal or higher than the temperature of the maximum value for Tan δ and smaller than the melting point of the polymeric recording medium. A single pass inkjet printer is also disclosed.
