ABSTRACT:
A decorative relief finished surface is formed by applying to the surface of an object or substrate to be patterned an undercoat of coating material to a predetermined thickness, and forming an uneven pattern having a variety of projections on coated surface a plurality of times with a rolling device having a plurality of convex parts of curved continued, disconnected or perforated line shape which are formed in a random manner, with the intervals between the convex parts being substantially equal to each other, or by spraying coating material with a spray gun so as to form a multiplicity of projections of varying height. Then, the top portions of the projections of the partially hardened surface which extend beyond a predetermined height are pressed with a pressing roll, such that the projections are uniformly flattened to a predetermined thickness while the rest of the convex parts are left unflattened. The pressing roll is made of a hard or semi-hard, air-permeable, porous material.
