ABSTRACT:
The present invention provides a method for forming a pattern on a synthetic wood board to form, on a surface of the synthetic wood board, a pattern such as wooden grain and the like which is close to natural wood, to enhance the reality of woody like appearance. The synthetic wood board is formed by mixing 35-80 wt % of thermoplastic resin material and 20-65 wt %. By a first grinding process, the synthetic wood board is formed at its entire surface of at least one side thereof with a large number of wound stripes in one direction. By a colorant coating process, a colorant is coated on the surface on which said wound stripes are formed, the colorant impregnates in wood meal on the surface to generate blur. And some colorant remain in recess portion of the wound stripes to form recess pigment layer. By a second grinding process, the entire surface on which the colorant is coated is ground and abraded except the recess pigment layer to form a large number of the wound stripes, thereby forming a pattern having woody like appearance. By a woody grain printing process, a woody grain pattern is printed on the abraded surface. With these process, a pattern having woody like appearance is formed by synergism of the pattern and woody grain pattern.
