An inkjet printing method for producing images durable for outdoor usage including the steps of: a) inkjet printing on a substrate a UV curable colourless primer including monofunctional monomers in a range of 40 wt% to 65 wt% based on the total weight of the UV curable colourless primer; b) at least partially UV curing the inkjet printed UV curable colourless primer; and c) inkjet printing on the at least partially cured UV curable colourless primer one or more UV curable colour inkjet inks including monofunctional monomers in a range of 30 wt% to 60 wt% based on the total weight of the UV curable colour inkjet inks; wherein a ratio of the wt% monofunctional monomers in the UV curable colourless primer over the wt% monofunctional monomers in the one or more UV curable colour inkjet inks is between 0.65 and 2.10. |
