Abstract:
1. A method of dot matrix printing an image on a printing medium using radiation curable compositions, the method comprising the steps of: printing the image 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 comprising 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, and before printing a next sub-image from the set of sub-images, actively rendering the dots of the previously interstitially printed sub-image non-migratory by exposing them to radiation wherein an interstitially printed sub-image is formed during a single printing pass.
