A method and apparatus for dot matrix printing of an image on a printing medium using radiation curable compositions is described. The image is printed using the radiation curable composition as at least one set of mutually interstitially printed sub-images, each sub-image comprising a set of dots, a dot consisting of a number of droplets applied on top of each other, each droplet being formed from one of a plurality of radiation curable compositions, the droplets mixing on the printing medium thus forming the dot with a specific grey level. Before printing a next sub-image from the set of sub-images, the dots of the previously interstitially printed sub-image are actively rendering non-migratory by exposing them to radiation. <IMAGE>
