Method for manufacturing a board having a three-dimensional wood grain on the surface thereof

A method for manufacturing a board having a three-dimensional wood grain on the surface thereof, the method comprising the steps of:

• (S.1) obtaining wood grain information and processing the information to generate a wood surface database;
• the database including at least an underlying wood grain printing dataset and a three-dimensional wood grain printing dataset;
• wherein the three-dimensional wood grain printing dataset includes a two-dimensional three-dimensional wood grain printing shape data subset corresponding to the underlying wood grain printing dataset and a three-dimensional wood grain printing depth data subset corresponding to the three-dimensional wood grain printing shape data subset;
• (S.2) assigning the underlying wood grain printing dataset to a first printing device;
• assigning the three-dimensional wood grain printing dataset to a second printing device;
• (S.3) using the first printing device to output on the surface of the board using the underlying wood grain printing dataset, to obtain an underlying wood grain layer matching the wood grain information;
• (S.4) using the second printing device to output wood grain precursor liquid using the three-dimensional wood grain printing dataset, to obtain a wood grain precursor for forming a three-dimensional wood grain matching the underlying wood grain layer, and the height of the wood grain precursor corresponding to different three-dimensional wood grain printing depth data subsets.
