Abstract: A method for inkjet varnishing a substrate includes the steps of jetting a micro-pattern of a varnish having a viscosity of less than 30 mPa·s at 45° C. and at a shear rate of 30 s−1 to a portion of the substrate by one or more printheads having nozzles with a nozzle diameter of no more than 30 μm, and at least partially curing the micro-pattern within 500 milliseconds after jetting to provide a micro-roughness to the portion of the substrate.

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.
