Abstract

An automated or semi-automated process for staining/finishing a wood article, preferably unfinished wood, and/or wood articles from which the finish has been removed, with a stain (oil or water based) containing a plurality of fluorescent dyes and/or pigment. The automated or semi-automated wood staining/finishing process, or at least one step thereof, is performed on pre-programmed automated equipment in (a) a flatline wood staining/finishing system, (b) a hangline wood staining/finishing system and/or (c) a towline wood staining/finishing system. The contrast between heartwood and sapwood features of the wood grain of the article is reduced to a desired degree by bleaching, and the bleached wood treated with a stain formulation containing a plurality of fluorescent dyes and/or pigment. In each instance the color of the stain shall appear in varying intensity depending upon the uptake thereof in the heartwood or the sapwood.
