The invention discloses a wood sign manufacturing method. The method is characterized by comprising the following steps that A, an anticorrosion dried wood plate is selected, and a numerically-controlled machine tool equipment is used for carving the outer contour of the wood plate into a shape; B, frosting equipment is used for grinding the surface of the wood plate flush and polishing the wood plate; C, carving equipment is used for manufacturing characters or patterns, needing to be displayed, of a sign into a sand blasting baffle model; the carved baffle model is pasted on the wood plate smoothly, and sand blasting equipment is used for blasting sand on the wood plate on which the baffle model is pasted; D, a spray gun is used for carrying out base color overall spraying on the whole wood sign, after overall spraying is carried out, the wood sign needs to be dried for 8-12 h, after the base color of the wood sign is dried, the baffle model on the wood sign is taken down, and printing equipment is used for coloring and printing the shield part of the baffle model; E, finally, overall UV film pouring is carried out on the sign, the surface of the wood sign is cured. The wood sign has the advantages of being colorful, not prone to fading, long in anticorrosion period and the like, bottom grain is concave and convex, and is natural wood grain, and the color and the wood grain are integrated.
