To obtain a woody plate material having an impression of high quality material easily and at a low cost by processing a surface of a woody material, such as a veneer, plywood or a plate material obtained by lumbering, to have a grain pattern and touch which closely resemble a desired natural wood. When embossing a xylem surface pattern such as conduit pipes, and printing a grain pattern such as a cross grain, simultaneously on a surface of a plate-like woody material A1, an embossing roller 3 having a xylem surface pattern which matches a desired grain pattern projected on its surface is used for embossing a concave xylem surface pattern on a surface of the woody material A1 and, simultaneously, the embossed portion is supplied with ink by an ink feeding device, and then, a grain pattern which matches the xylem surface pattern embossed on the surface is printed by a printing roller 8 so as to obtain a woody plate material having a desired grain pattern.
