Patent ID: 7108031

Claim:
A method of making a pattern in a wood surface, said method comprising: a) providing a wood member which has a wood surface and wood cells formed in a wood cell structure which comprises a plurality of wood cell structure portions at higher and lower levels relative to said wood surface; b) embossing said wood member at said wood surface to form a pattern of ridges and valleys at said wood surface, with the wood cell structure comprising ridge wood cell structure portions at higher and lower levels, valley wood cell structure portions at higher and lower levels, and also transition wood cell structure portions which are located between adjacent ridge and valley wood cell structure portions and which are slanted and are at higher and lower levels, with the valley wood cell structure portions being displaced downwardly relative to the ridge wood cell structure portions and with the transition wood cell structure portions slanting downwardly from adjacent ridge wood cell structure portions to adjacent valley wood cell structure portions; c) removing at least upper portions of the ridge wood cell structure portions and upper portions of the transition wood cell structure portions to form a modified exposed surface comprising exposed wood surface portions which comprise lower level ridge portions of the ridge wood cell structure portions, and of higher level valley portions of the valley wood cell structure portions, and exposed wood surface portion of the transition wood cell structure portions; whereby the modified exposed surface has a contrasting surface pattern with a three-dimensional visual effect.
