A method of forming a flexible printed material is described. The method comprises applying a layer of primer onto a flexible substrate; electrostatically printing onto the layer of primer a liquid electrostatic ink composition; applying a curable overprint varnish composition onto the printed electrostatic ink composition and curing the overprint varnish composition using electron beam irradiation. The curable overprint varnish composition comprises an ethylenically unsaturated monomer, an ethylenically unsaturated oligomer, or mixtures thereof, and less than 10 wt. % of a cross-linking additive based on the total weight of the curable overprint varnish composition. A flexible package comprising the flexible printed material is also described.
