ABSTRACT:
A method of manufacturing an article carrying a relief image intended for printing comprises exposing to an appropriate activating radiation the surface of a receptor material having at least a part of its thickness from the surface thereof formed of a homogeneous mixture of a solid material whose aptitude for softening when heated is modified when it is exposed to said activating radiation, and of at least one substance which releases a gas upon being heated, in such a manner as to transcribe therein a latent image in the form of differences in aptitude for softening and by heating the receptor material to a temperature such that its exposed parts and its non-exposed parts are softened to different degrees, said temperature being at least equal to that at which said substance releases said gas, thereby causing swelling of the exposed parts and the non-exposed parts to different heights thereby forming a relief image based on differential capacity for softening.
