A method is disclosed for making on a transparent receiver material a continuous tone image, e.g. for medical diagnostic purposes, with an obtainable maximal transmission density in the visual region greater than 3.0, by means of ink jet. The method comprises ink-jetting combinations of at least one liquid black pigmented ink and at least one liquid grey ink to a transparent receiver comprising an ink receiving layer, a transparent support and a backing layer, said ink receiving layer comprising a N- containing polymer, preferably gelatin, as binder, and being substantially free of particles having an average size larger than 1 mu m. Preferably the transparent receiver exhibits a haze value between 10 and 20 %, determined according to standard test ASTM D 1003, due to the presence of a spacing agent in the backing layer.
