    Abstract: A radiation curable inkjet printing method for producing printed plastic bags comprising the steps of:
    a) providing a web-like polymeric substrate having a maximum value for Tan δ between 40°C and 110°C;
    b) providing a single pass inkjet printer having at least one page-wide printhead or at least one set of staggered printheads, means for transporting the web-like recording medium and curing means;
    c) jetting onto the web-like 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
    d) 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

    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.
    A single pass inkjet printer is also disclosed.
