PROBLEM TO BE SOLVED: To easily perform gradation coloring by coating by bringing a coating roll having fine projecting and recessed parts uniformly formed on the surface of an elastic layer into pressurized contact with the surface of a ceramic based plate having a surface projecting and recessed pattern to fix the pressing force to a reference surface set in the thickness direction of the ceramic based plate. ;SOLUTION: A coating material supply roll 3 is brought into contact with a coating roll 1 for applying gradation coating on the surface of the ceramic based plate 2 and a coating material 5 is supplied to the coating roll 1 with the coating material supply roll 3. The coating roll 1 is composed of an intermediate elastic layer formed around a metallic core and a surface elastic layer and the fine projecting and recessed parts are uniformly formed on the surface of the surface elastic layer. As a result, the density of the fine projecting and recessed parts transferred from the coating roll 1 are automatically controlled in accordance with the press contact force to perform the gradation coating by bringing the coating roll 1 into pressurized contact to fix the pressing force to the reference surface 2a set in the thickness of ceramic based plate 2 having the surface projecting and recessed pattern.;COPYRIGHT: (C)2000,JPO
