Method of molding a door skin and an etched plate for the same
View Patent ↗The present invention is directed to a door skin having an exterior surface with an woodgrain pattern formed therein, and an etched plate for use as an embossing plate or with a molded die set, for forming the woodgrain pattern in the door skin. The exterior surface has outer portions lying on a first plane, spaced grooves recessed from the plane of the outer portions, and halftone portions. The halftone portions have spaced protrusions defined by channels, wherein the channels are recessed from the plane of the outer portions.
1. A method of making a stained door skin, comprising:
pressing an etched plate against a substrate to mold a door skin with a stainable exterior surface comprising molded grooves and molded halftone portions, the grooves configured with variable depths and lengths with respect to one another and variably spaced with respect to one another to collectively simulate an appearance of a naturally appearing wood grain tick pattern, the halftone portions configured to receive and retain sufficient stain to simulate an appearance of darkened naturally appearing wood grain background tone, the etched plate has an inverse configuration to the molded grooves and molded halftone portions; and
staining the stainable exterior surface of the door skin with a stain.
2. The method of claim 1 , wherein a first area of the exterior surface has a first density of the halftone portions retaining a first amount of the stain to provide a first tone, wherein a second area of the exterior surface has a second density of the halftone portions retaining a second amount of the stain to provide a second tone, and wherein the first tone differs from the second tone to simulate multiple naturally appearing wood background tones of different degrees of darkness.
3. The method of claim 1 , wherein the substrate comprises sheet molding compound, polystyrene, or polypropylene.
