The present invention provides a method for printing energy-curable ink and coating compositions that have good adhesion to substrates, good print quality, solvent and scratch resistance, and low potential for migration of uncured monomers. The method comprises the steps of printing the ink or coating onto a substrate; partially curing the printed ink or coating by irradiating with UV energy; optionally printing and partially UV curing additional ink layers printed on the first layer; and completing curing via exposure to electron beam radiation, wherein the EB cure dose is greater than or equal to 20 kGy, and the accelerating voltage is greater than or equal to 70 keV.
