The present invention provides a method of inkjet printing, comprising: (i) inkjet printing an inkjet ink on to a substrate, wherein the ink comprises: an N-vinyl monomer selected from N-vinyl caprolactam, N-vinyl pyrrolidone, N-vinyl piperidone, N-vinyl carbazole, N-vinyl formamide, N-vinyl indole, N-vinyl imidazole, N-vinyl acetamide, and mixtures thereof; one or more difunctional monomers; and a radical photoinitiator; and (ii) curing the ink by exposing the printed ink to a UV radiation source, wherein the UV radiation source moves relative to the substrate at a speed of 70 m/min or more.
