The present invention provides a method of multi-pass inkjet printing comprising: (i) providing an inkjet ink comprising a radiation-curable monomer and a photoinitiator; (ii) jetting the ink via a printhead on to a substrate, wherein the ink is applied in multiple passes of the printhead with respect to the substrate, with each pass jetting a portion of ink in a layer on the substrate, with a first layer being jetted directly on to the substrate and subsequent layers being jetted onto the preceding layer, to build an image formed of the multiple layers; and (iii) exposing all of the layers of ink to actinic radiation to cure the ink, wherein the order of jetting the layers and curing is that pairs of layers are applied to the substrate without exposing the first layer of the pair to actinic radiation prior to the second layer of the pair of layers being applied, curing the pair of layers simultaneously by exposing the pair of layers to actinic radiation, and repeating until the image is formed.
