    摘要: On a surface of a decorative paper, vessel perforation of natural wood is reproduced by an offset groove (100) consisting of three steps of embossing grooves (110, 120, 130) of the nesting structure. Respective grooves are such that they are deeper according as positions thereof shift to the internal, and are disposed in a manner to be eccentric in a length direction. Within the groove, a convex bank portion (140) in which the bottom surface is linearly protruded is formed. An embossing plate for processing such an offset groove is prepared on the basis of a vessel cross section pattern inputted by using natural wood. The inputted plane vessel cross section pattern is replaced by an approximate elliptical figure. A three-dimensional virtual vessel perforation model is determined by calculation using the elliptical figure. Equi-depth lines for set predetermined depths are extracted from the three-dimensional model and contour figures of embossing grooves (110, 120, 130) are obtained. Patterning masks using respective equi-depth lines as contour lines are respectively prepared to repeatedly carry out patterning processing with respect to the plate material by successively using respective masks in order from shallower depths to thereby prepare an embossing plate.
