    Abstract: A method for making a flexographic printing master including:
    a first step of providing a flexographic printing support (1);
    a second step of applying image wise with a first resolution a layer of a radiation curable liquid (2) partially covering the printing side of the support;
    a third step of flood exposing the applied radiation curable layer to fully cure the layer; and
    a fourth step of image wise laser engraving the cured layer with a second resolution (3) which is higher than the resolution of the second step.
    An imaging apparatus for performing the above method is also disclosed.

    Abstract: A method of making a flexographic printing sleeve forme comprising the steps of:
    (i) formation of a sleeve body by providing one or more at least partially cured uniform layers on a sleeve carrier;
    (ii) formation of a relief image on said sleeve body by imagewise jetting a curable jetting fluid;
    (iii) optionally overall post-curing;

    characterized in that between formation of the sleeve body and formation of the relief image no polishing or grinding is performed.
